Experienced, Knowledgeable, and Responsive…

I sought legal representation from multiple firms for a complicated clearance revocation, whistleblower, and EEO case. My research revealed that few attorneys in the DC area have successfully handled cases with such complexities. My initial consultation with Mr. Mahoney reassured me that he had the... experience and expertise I needed. No federal civil servant wants to face such matters, especially at the end of their career. But if you do, it’s critically important to have the best legal guidance and support. I’m confident that Mr. Mahoney is the best choice for me.

Impressive!

Talking with John Mahoney was more impressive than I had imagined it could be. My consultation felt as though I had found the perfect fit for my EEO case and none of the previous consultations I had with other firms felt that way. He is a compassionate professional that knows the law. I learned far m...ore from him than I had from 3 other attorneys combined. I knew he was who I needed and was meant to represent me. I am so inspired and grateful.

Hired after our consultation

Mr. Mahoney was very thorough and prompt. During my consultation he gave me some pointers and didn’t waste any time talking with me. I’ve been harassed by management and denied FMLA leave and discriminated against my disability and denied temporary accommodation. I shouldn’t be harassed on a daily ...basis and the agency allows this type of behavior. I can’t wait to be able to work in a peaceful work environment and be treated fairly. I am confident Mr. Mahoney & his team will be able to settle this issue in a timely manner.

Appreciation

I want to thank you so much for your availability, follow-up, and especially the attentive and prompt replies have been invaluable, John Mahoney. He listened carefully as I laid out my situation, provided me an initial assessment of my case, and reassured me that I have a lot of protections in place ...under Federal law and policy. Having never experienced on going, everyday discrimination in the workplace, which has, been affecting my health, well-being. and exacerbated my PTSD.I had no idea how to handle discrimination claim, and the feeling of going into it alone was very intimidating I reached out to a number of law firms, and consulted with an attorney in a different firms who just said, "file an EEO complaint," or talk to your union and they did not seem in the least bit interested in taking on my case. He described the way ahead clearly. I cannot describe the feeling of relief that I have, knowing that I have experienced Federal Labor law Attorney to help me navigate the process. I am no longer all alone in fighting an extremely stressful and emotionally draining situation. I want the discrimination to stop, and the situation to be resolved fairly and quickly, and John Mahoney gives me every confidence that outcome will transpire.

Candid, Knowledgeable Counsel

I've never had any trouble in my federal service until I transferred to an organization with mediocre leadership and arbitrary performance standards. I was rather shocked to receive a Notice of Proposed Removal via mail when I was hospitalized for a medical condition incurred during military service.... I knew I needed an attorney with experience in federal employment law due to the complexity and differences between private sector and government employment. I had searched for representation and tried to tell my side of the story to other law firms only to be met with indifference and told I needed to pay an $8000 retainer to have them even consider taking my case. I was very fortunate to find Mr. Mahoney's firm. I was given a free consultation from Mr. Mahoney himself (rather than an office manager) and he took the time to listen and consider the merits of my case. Like many federal employees, I'm not wealthy and was relieved to hear that the firm's initial retainer fee was around $3000 which was less than half of what other firms wanted and gave me the comfort to know I could at least be able to afford some representation. Mr. Mahoney's firm was able to prevent my Agency from illegally firing me, force the Agency to hold the supervisor accountable for their actions, and minimize their attempts to retaliate against me for exposing a supervisor's malfeasance." Firm Partner Melissa Lolotai exemplifies the term 'Counsel' in the highest and noblest sense of the word. Ms. Lolotai was able to expertly cut through my Agency's falsifications and gross inconsistencies and explain the legalities of every aspect and phase of my case. I was able to take comfort in the fact that I had a highly experienced and sharp attorney to speak on my behalf so I could focus on trying to get healthy and not worrying about being subject to an illegal Notice of Proposed Removal and later was able to shield me from almost all of my Agency's brutal attempts to retaliate against me, to include a Proposed 30 Day Suspension for exposing Agency malfeasance. Ms. Lolotai's arguments were so strong that Agency's Attorney was in the words of the Agency, "unresponsive for requests for information" for well over 3 months and the GS-15 Deciding Official opting to retire and send the decision higher rather than issuing a decision. Ms. Lolotai was extremely caring and compassionate and helped me keep my sanity even as the Agency attempted to gaslight me for several months and retaliate. Ms. Lolotai was able to also keep my Agency's EEO office honest when I filed my EEO complaint and helped me expose my senior leadership's retaliatory animus and deceptions.
