Atty Letha Miller
There were no areas of Atty Miller’s, and this firms service that was anything but outstanding! Atty Miller is professional, knowledgeable and kind. She is more than well versed in Federal issues and processes which helped tremendously in navigating the complex issues. Her experience as a once employee herself of a Federal agency and her vast knowledge made her efficient which saved me money. Her expertise and kindness was calming in a stressful and scary time. I highly recommend Atty Miller and this firm!

EEO Consultation
Mr. Mahoney promptly responded to my request for a consultation on my complaint and provided valuable guidance and insights on the EEO process for federal employees. However, due to timing issues, I did not end up hiring his firm.

I'm in! Consultation was AMAZING!
My consultation with Mr. Mahoney was amazing! I immediately retained his services. He is knowledgeable, detail-oriented, and honest. Some attorneys tell you what you want to hear; he told me what I needed to hear! He explained regulations and case law in expert detail. I'm in!

Thank you
I had almost given up on my EEOC case until I reached out to Attorney Mahoney, and he promptly responded to my consult request at 8 p.m. He thanked me for my service to our country. He said his firm would be honored to represent me. I could not believe it. My discovery was ending in approximately 2 weeks, yet he was still willing to consult on my case. During our consultation, Attorney Mahoney was more than generous with his time. His consultation was well over an hour and a half with no mention of additional fees for going over my case. He was personable, empathetic and had a unique way of making me relax under such stressful circumstances. He presented my options and was forthcoming. He was willing to step into a case that was so poorly handled and unsure if it was even salvageable. I appreciated his honesty and knew this firm was my last hope. All I can say is if you need help with a federal agency case, please do not waste your time or money on any other attorney. You must call this firm. Attorney McEntire and Attorney Mahoney are well versed in federal employment law. Attorney McEntire has remained focused on meeting discovery deadlines and filing motions. I am confident that they are looking out for my best interests and cannot thank them enough for guiding me through this difficult process. Although I do not have a conclusion to my case, I am now confident that I have two attorneys who are looking out for my best interest.

Very confident at initial consultation
Mr. Mahoney is the great federal employment attorney I have ever worked with. At the first meeting, I can tell he is a top expert in federal employment law. He explained all on my case with possibility and answered to all questions I have. He also has a great communication skill and make him to believe. Hope he can take my case and look forward to work him.

Initial Consultation
I contacted Mr. Mahoney office after a bad experience with another attorney, I had a dealine to appeal my case which is fast approaching. I was reluctant and ready to give up. Mr. Mahoney immediately contacted me to setup an initial consultation. On the day of the consultation, there was a mixed up with the appointment, and the secretary said he would call me later that day since he had back to back appointments and couldn't meet with me at my scheduled appointment. I had anxiety attack thinking no one was going to call me. Let me tell you Mr. Mahoney called me about an hour later and listen and discussed my case. He made me feel he already know my case. Mr.Mahoney was helpful and transparent. I was so relieved. I am looking forward to working with Mr.Mahoney and his staff. I will definitely submit an update review when my case is completed

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 more 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.

Initial Consultation Feedback
Attorney Mahoney prepared extremely well for the call and gave me the full confidence it was worth my investment to ask his firm to represent me in filing an EEO complaint. He was honest about my chances of success. He focused on asking specific questions that would support my claim applying his experience in dealing with the administrative judges who would decide my case. We discussed specific Govt individuals’ backgrounds and motives and other key context to give him a full picture of the complexity of my situation. A former colleague and sitting US judge recommended Attorney Mahoney to me. I am pleased with this referral. I have already been assigned a partner who will work with Attorney Mahoney to proceed with my case. I am resting easier knowing I will not carry this burden by myself. I am very pleased with my initial consultation and look forward to a successful outcome.

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.

Someone on my side!
I had my initial consult with Mr. Mahoney and I have to say my stress level significantly decreased after our discussion. Just knowing I have an advocate committed to helping me resolve my challenge is a HUGE relief. He is very knowledgeable and I very much appreciated his ability to break down complicated legal processes in a clear and concise manner. His approach to resolving my issue was very straightforward and easy to understand. I am happy to retain his services and look forward to working with him.

Excellent Rapport
My consultation with Attorney Mahoney was provided great relief and peace of mind with regard to my Federal employment case. He was extremely knowledgeable, and very quickly boiled the case down to layman's terms, which I could understand, making it obvious to me that he was well versed in all aspects of Federal employment law. It was clear to me that he was writing as we spoke, and his experience was evident as he rattled off points of law and regulation. With a very calm and friendly demeanor, Mr. Mahoney and I developed an instant, positive rapport that was very upbeat. He made it clear that he understood my case and that he could relate to me, and that he would do everything he could to bring my case to a just outcome. I have hired Attorney Mahoney's firm and I would advise anyone seeking legal representation for a Federal employment matter to consult with him. The fees are reasonable and I can move on with other things in life, confident that this legal matter is in good, capable hands. The peace of mind is priceless.
