“I am very thankful to David Marshall and Dan Edelman for all of their hard work and efforts in successfully resolving my whistleblower claim against my former employer, a federal credit union. Throughout the entire process, it was very obvious to me that the KMB team worked together very effectively, and they made a very stressful process for me as positive as possible. During the mediation session with my former employer, I felt that we were as well prepared as possible and I had high hopes of reaching a fair settlement. I was very pleased with the results, particularly knowing that the credit union had engaged a formidable firm to work in their defense which had been a tough negotiator in the past. The KMB team was very professional throughout the process.”

“I was represented by Debra Katz and Avi Kumin of Katz, Marshall & Banks and was very pleased with the legal counsel and services they provided. They are very effective and compassionate advocates who genuinely care for, and will protect and defend, their clients. Their focus on, and expertise in, employee rights and workplace fairness is exceptional. I strongly recommend the firm if you have the need for aggressive yet compassionate representation.”

“When I was looking for a law firm to represent me in a discrimination against working mothers case, the name Katz, Marshall & Banks was the firm that everyone downright insisted I work with, and I soon learned why. Lisa Banks, Debbie Katz, Dan Edelman, and the rest of the team at KMB handled my case with incredible expertise, professionalism and compassion, which resulted in a settlement that was victorious for me on many levels. Before I engaged with KMB, I felt victimized, somewhat helpless and very intimidated. They quickly became a powerful advocate for me, and they championed my case in such a way that left me feeling confident and empowered.”

Executive with a leading public relations firm


“Partner Avi Kumin and his associate Julie Zibulsky were exceptional in the strategic analysis, development, and implementation of my employment case. I was involved in a particularly challenging work environment and employment case and in knowing this, Avi and his team worked rapidly to collect and summarize the facts of my case. Avi then effectively implemented his strategy to come up with a highly successful resolution in a very short period of time. Their speed and efficiency in responding to any additional employment challenges I faced was magnificent as well. I am very happy with the results achieved by Avi and Julie. I would highly recommend Katz, Marshall & Banks to anyone who is engaged in or is considering an employment legal action.”

Senior Director of Operations in the pharmaceutical industry, client in a whistleblower case


“In 2011 through 2012 I found myself to be in situation that read like a case study from graduate school. I had been recruited and hired by an aerospace firm that served an impressive group of federal customers. Unfortunately, it soon became apparent that my boss was engaging in unethical and illegal behaviour which I subsequently reported to the U.S. government as well as through the corporation’s channels and processes. I found myself a whistleblower and facing retaliation from the corporation. At that time I retained KMB. The entire team at KMB were impeccably responsive, knowledgeable and thorough. David Marshall, Dan Edelman and everyone else at the firm provided flawless counsel, kept me in the loop at all times and we achieved a very favorable outcome. KMB has my highest possible praise and endorsement for your legal needs and unforeseen challenges.”

“Avi Kumin’s professionalism, expertise, commitment, and attention to details while handling my case were outstanding. Avi and Alison Asarnow stepped in and negotiated a settlement plan that not only kept me out of court, but also prevented any negative references or information being leaked out to possibly hinder my future growth as a professional. Avi spent one on one time with me explaining the entire legal process which fortunately resulted in the most positive outcome for my individual case. I would highly recommend Avi and the team at Katz, Marshall & Banks.”

Director of Human Resources, client in an employment discrimination case


“When I needed a law firm to help me make the right decisions regarding the actions of my employer, I reached out to friends in the legal community. They pointed to one firm: KMB Legal, saying I would be in great hands. Debra Katz, Dan Edelman, and the rest of the team at KMB understood the complexities of my situation and they treated me like an individual rather than just another case. Not only are they the best attorneys in employment law practice but they are also passionate about helping people. I feel very fortunate to have been their client.”

Executive at a global IT services contractor


“Avi and his team were quick to respond to my concerns; offering various options to satisfy my claim of Age Discrimination. I was very pleased with the time and in-depth detail discussed as we moved forward in the case – and the ultimate successful resolution. He was considerate of my concerns; a willing advocate and made the process understandable and easy. I would highly recommend Avi and his team.”

“I sat at home bewildered in the days after my wrongful termination for pointing out significant and substantial safety violations in a coal mine to my employer, overwhelmed this had happened to me. After speaking with a friend in the underground mining industry he suggested I contact Katz, Marshall and Banks and discuss my situation with them. After being accepted as a client, I went from feeling alone to knowing I had the ‘best of the best’ at my side, working to defend my name. In a very short period of time, Alexis Ronickher, on the verge of winning an order of reinstatement from MSHA, was able to reach a significant settlement with my former employer. My gratitude for KMB’s hard work cannot be expressed in words. They give me back my good name and sent a message to my former employer that underground coal mine safety issues should be corrected, not simply swept under the rug.”

Underground Coal Miner


“David Marshall and Abigail Cook-Mack are two of the finest professionals I have ever met. They showed compassion, resolve and a tenacity that is simply world class. My case was extremely complicated and spanned many years and involved the most senior management in my institution. Taking on the most powerful people on Wall Street in the name of justice and doing the right thing involved enormous risk, but KMB put all of their considerable resources behind me, and in the end I was rewarded with a seven figure settlement from my former firm. My family and I are truly grateful to David, Abby and the KMB team for helping us right a wrong and allowing me and my family to move on with our lives satisfied with an exceptional outcome. Their track record is second to none. A call from KMB to your former or current employer sends instant chills up their spines. They bring decades of experience and a culture of compassion you need to experience to appreciate. KMB specializes and some would consider the firm a boutique. Make no mistake: they are as feared, if not more feared, than the largest law firms in the country. My result and their results speak for themselves.”

Former managing director at a major financial institution


“Debra Katz, Alexis Ronickher, Alison Asarnow and others at the firm represented me in my 5 year sexual harassment battle against the Andre Chreky Salon. Being sexually harassed at work is a totally demeaning experience that takes away your self-esteem. Being a litigant is incredibly hard emotionally. These lawyers were there for me every step of the way. Not only are they incredible lawyers — we achieved a $2.3 million jury verdict after a two week trial — but they are amazing people. I could not have asked for more compassionate, committed lawyers to have in my corner.”

“Lisa Banks focuses on the client and provides expert analysis and legal counsel that is customized to fit the client’s specific situation and needs. Whether it is employment contracts or employee law matters, the Lisa and other firm members are savvy, persistent and successful in obtaining favorable and reasonable outcomes for their clients. I have used them several times and have recommended them often to colleagues who are as equally satisfied with their approach and services.”

Chris McEntee, Executive Director/CEO, American Geophysical Union


“I approached KMB legal when I thought nobody cared about me or the drugs that were going out the door. KMB legal did care about both the patients we serve and me. They educated me on the process and the respective risks. After engaging KMB legal, it was like a great burden was lifted; the worry and insecurity of it all went away. David Marshall and Daniel Edelman were outstanding in representing me to a successful outcome. Moreover, I felt that we struck a blow for the unsuspecting patient that needed pharmaceuticals for better quality in health. You have choices in who represents you but as for me, KMB was the best and only choice for strong sound legal representation.”

“From the moment Debra Katz began representing me in a wrongful discharge matter, I could sense her passion for justice. Every step of the way, I felt tremendously supported by her law firm. Debra has a solid understanding of the tactics employers use to veil illegal and unethical employment practices, and she confronts them head on. Without a doubt, Debra’s determination and skillful negotiation with opposing counsel helped me reach a successful and impressive out-of-court settlement in my case.”

“My experience as a client of Avi Kumin and Alison Asarnow at Katz, Marshall & Banks law firm was the best legal experience I could have ever imagined. The professionalism, high quality of work, efficiency, effectiveness, patience, quick responses and friendly collaboration were all by far superior. I was incredibly fortunate and grateful to have had the opportunity to work with such a top notch team, where the lawyers advocate for your rights and truly care about helping others and making the world a better place. My human rights were terribly violated, and they successfully advocated for my human rights. Words cannot describe what that feels like.”

“The fraud in skilled nursing facilities is abhorrent, and I finally got fired for complaining to management about it. Thanks to good luck and the Internet I found David Marshall and Alexis Ronickher at Katz, Marshall and Banks. They understood the issues and helped me get a settlement. Katz, Marshall and Banks levels the playing field. I’m very grateful!”

“In 2010 I retained Katz, Marshall & Banks to represent me in a wrongful discharge case involving a not-for-profit organization. I worked very closely with Debra Katz and her colleagues and was very impressed throughout the process with their rapid response time, their high level of professionalism, their creative approach to addressing and resolving issues, and their strong commitment to social justice and human rights. We worked closely together to tailor a strategy and work plan that best suited the case, and I was very pleased with the efforts by Ms. Katz and her team to resolve the issues in question. I strongly recommend working with Katz, Marshall & Banks.”

P.M., former Chief Executive Officer of a not-for-profit organization


“My initial consultation with David Marshall was met with an earnest interest and insightfulness as to the applicable laws that governed my case. While some of the discussion was consisted of various legal terms and case quotes, David took the extra time to put this in layman’s terms. I was very comfortable making decisions based on the education that David provided. David was informative, understanding and most importantly, supportive of me – I didn’t feel alone. I am so thankful that I had David Marshall and the KMB Legal team representing me for a fantastic outcome!”

“I had a great experience with Debbie and her team. They quickly put my Sarbanes-Oxley whistleblower case together and worked hard with the DOL/OSHA and opposing counsel to negotiate a settlement that I was happy with. It was clear that Debbie is one of the country’s leading employment attorneys and her knowledge and experience helped me manage the stress and anxiety that goes along with these types of claims.”

“Lisa Banks and Mike Filoromo did more than represent me during my sexual harassment case. They supported me. They acknowledged how stressful the situation was and validated my feelings by pursuing my former employer for justice. I knew I was in good hands the entire time. I recommend this firm to anyone needing good, strong, intelligent representation.”

“Ms. Katz is a passionate attorney with a lot of experience and was able to resolve my case quickly. KMB has excellent attorneys and their employees were wonderful at all levels. Communication with the firm was excellent. Ms. Katz used her team of experts to build the best case on my behalf. Ms. Katz always made me feel as if I were her only client, and that my challenges were justified.”

A.P., former manager of a trade association


“David Marshall is an exceptional attorney. His deceptively easy-going personality is a perfect match for anxious clients, respectfully guiding to the best solutions with such grace. His knowledge is top-tier, and his integrity — which I consider the highest calling for an attorney — is unassailable. His ability to manage a highly complicated legal project with the right touch at each point is one of his best professional abilities. Legal situations can take a longer time than a client may expect, and each phase is different, calling for varying skills. David and his well-chosen team have them all.”

“It was extremely difficult exposing the problems at Fannie Mae, and navigating the related contentious and complicated environment. I set a very high level of expectations for legal counsel and the unique capabilities counsel would need. Debra Katz and her colleagues at Katz, Marshall & Banks not only met those expectations, but exceeded them in every way.”

“Avi Kumin and the rest of the folks at KMB did their homework, which was pivotal to the successful outcome of my case. Attorneys and support staff were professional and buttoned down and comfortable to work with during a challenging time. They always kept all options at hand. In our town of attorneys, trusted counsel recommended the firm originally and I would strongly do the same.”

“Words fail to express how thankful I am to have been represented by Katz, Marshall & Banks. Throughout what was a very difficult time for me, I always knew that I was in good hands. Debra Katz and her team consistently kept things on track and performed above and beyond expectations. I am eternally grateful for their assistance and will forever be impressed with what they were able to achieve in the face of great adversity.”

“Early in 2004, I was fired from a Browns Ferry nuclear plant in north Alabama for bringing up safety concerns to the NRC. Katz, Marshall & Banks has been thorough in helping me with everything that I have had questions and concerns about. They have stood by my family and I throughout the course of this litigation. If you are looking for a law firm in regard to a whistle blower case action suit I would highly recommend using Katz Marshall and Banks. David Marshall, Matt Stiff, and the staff are unsurpassed in the work that they have done for me in regard to my case. To them you are not just a case number; you are individual person with a problem that should be rectified. In my opinion they have went above and beyond to help my family. They are a great law firm that has exceeded all of my expectations and I would highly recommend them to anyone.”

James A. Speegle Sr., whistleblower in the nuclear industry whose case KMB has been litigating since 2004 and is now on appeal before the 11th Circuit U.S. Court of Appeals


“I retained the services of Ms. Katz to represent me in an employment discrimination case because of her national reputation for being a hard-nosed and one of the best discrimination lawyers in the country. Her handling of my legal claim certainly proved this to be true and I found Ms. Katz to be compassionate, professional, and very easy to work with. Ms. Katz’s tenacity was essential to my reaching a settlement that far exceeded my expectations and my legal matter was handled in an expeditious manner.”

“Avi Kumin and Michael A. Filoromo, III did outstanding job in summarizing facts and organizing legal arguments. They carefully crafted the strategy based on research & analysis of a very complex situation, and with multiple iterative modifications produced an elegantly written and compelling case. The outcome was very satisfactory. As one can imagine, this was an emotional and stressful period, however, due to Avi’s and Michael’s excellent professional work, it was more bearable than it would have been otherwise. I am very pleased with the results and would highly recommend hiring this firm with superb lawyers.”

Chief Science and Technology Officer, pharmaceutical industry


“I found Debra Katz to be highly talented in her ability to grasp a complicated pharmaceutical whistleblower case and as it developed, present a clear, concise story. Debbie was always responsive to me as a client, yet managed the case efficiently; always taking care for expenses without limiting her ability to be effective. She aggressively represented me while analyzing the case honestly to the end of meeting what she saw as my best interest at all times. She never rejected or limited my input, but sought and used all the information she could. Her gift to depose is extraordinary, as was her intuition. I recommend her as highly as possible.”

Pharmaceutical whistleblower


“David Marshall represented me in securing a very good outcome in a high-profile, hard-fought whistleblower case against a powerful government agency. He not only went toe to toe with the agency’s lawyers at every step, but he also had the strategic ability, sense of timing and political know-how that it took to deal with a well-financed opponent that thought it could outsmart us and defeat us. And from our first conversation to the end, I always knew that David was 150% on my side.”

“Debra Katz and Lisa Banks represented me in a whistleblower lawsuit involving contractor fraud at a U.S. Embassy. In handling my case, they were clear in their strategy, uncompromising with regard to the law, and demonstrated a zeal for justice. They were in constant contact with me regarding status updates, and aggressive in filing a lawsuit on my behalf moving my case along in negotiations with opposing counsel. I could not have had finer attorneys handling my case.”

Jim Sauer, defense contractor whistleblower who served as a project manager for a Department of State contract


“David Marshall is a gifted attorney, always focused on the goal of representing his client aggressively and intelligently. David’s interactions with his clients are highly respectful of both the person and the situation, never reducing the reality to the level of a case. David was always thoughtful and responsible in the financial management of my case. I would highly recommend David to anyone in any situation, and am thankful to him and to his partner, Debbie Katz.”



“I can’t thank Lisa Banks and Debra Katz enough for their expertise, thoroughness and dedication in handling and prevailing on my SOX whistleblower complaint. They are by far the most knowledgeable attorneys on laws protecting individuals subject to workplace retaliation. More importantly, they are compassionate attorneys who provide support and make themselves available for you whenever you have a concern. Katz, Marshall Banks recognition as a top employment and whistleblower law firm is well deserved!”

Financial services SOX whistleblower


“I am an FAA aviation safety inspector who blew the whistle prior to the 2009 accident of Colgan Air 3407 in 2009 that claimed 50 lives. After the accident, I again blew the whistle; the FAA retaliated by taking my FAA badge and placing my job in jeopardy. I was most fortunate to retain the services of KMB. KMB well knows its way around the highest levels of federal office, including the Hill. Without the firm’s absolutely top-drawer representation, I believe I would have been fired; instead, I continue with the FAA. I highly recommend KMB to others who may find themselves in harm’s way.”

Christopher Monteleon, FAA Safety Inspector


“For five months, I tried (unsuccessfully) to resolve a whistleblower situation at my Midwest nuclear power plant. Katz, Marshall & Banks, LLP resolved this issue in less than six weeks. Thank you very much for your tenacity and discovering the truth. David Marshall, Dan Edelman, and Debra Katz took a very emotional situation from a big demotion to a promotion. My wife and I will be forever grateful for your professionalism and your execution of this case.”

“As an award winning sales representative for a large pharmaceutical company, blowing the whistle about government fraud was never a decision I took lightly. The immediate retaliation from my employer created a hostile and unbearable work environment. I retained Katz, Marshall & Banks because of the firm’s stellar reputation and proven track record. The Firm’s “take charge” approach made me 100% confident that I was being protected during this stressful situation. KMB attorneys were tremendous from start to finish. They negotiated an outstanding severance package on my behalf and got me out of an untenable situation.”

Sales representative at pharmaceutical company


“Debra Katz represented me in an employment discrimination claim. She exudes competence. She is very knowledgeable, straightforward, and confidence-inspiring. She let me know what to expect and kept me informed at every step of the process. She was also very personable. I have great respect for her integrity and abilities. And, this may sound cheesy, but I believe she is helping create a society that is more just.”



“Ms. Katz represented me after I reported corruption at a federal agency. I frequently recommend this lawyer to government employees who have personnel issues and need representation, particularly whistleblowers. She has strong integrity and commitment to her clients. I have complete confidence in her ability to provide excellent representation.”
