Fantástico abogado con un grupo de trabajo maravilloso.
Estoy muy satisfecha y feliz de haber contratado al Sr. Thomas O’Brien. El Sr. Thomas es un muy eficiente profesional y una excelentísima persona, su trato cordial, sincero y siempre dispuesto a ayudar me hicieron sentir segura. No podría haber tenido mejor abogado que él. Lidiar con estos casos de desabilidad es sumamente estresante, además a mí ya me había sido negado mi pedido de desabilidad y Medicaid, pero en la oficina del Sr. Thomas, todo me lo hicieron sencillo y sacaron mi caso adelante. El haber recibido un trato tan amable y en mi idioma me dejo maravillada. Realmente recomiendo al Sr. Thomas O’Brien a toda persona, y a las personas hispanas le digo que no van a sentirse defraudados. Mi más sincero agradecimiento al Sr. Thomas O’Brien y sus colaboradoras: Tracy Sugg y a Eva Valencia

2019 Rare Disability Approval
As the educated daughter of a Federal Court Clerk to Chief Justice; John C. Godbold, of the U.S. Court of Appeals for the Eleventh Circuit and an experienced litigation client, I write this review. If burnt out attorneys and bitter paralegals are a history you especially prefer to avoid, I urge you to consider three points about my experience with Thomas O’Brien. 1. I am a rare disability classification, which currently has no avenue of clinical testing for SSA disability approval. Furthermore, my physical disability is invisible to the untrained observer and it is more stigmatized than patients with epilepsy. Historically, SSA rejects patients with my diagnosis of severe disability. 2. Thomas O’Brien is a champion for rare disability types. His knowledge for these situations is not strictly derived from client representation. His meticulous focus, upon satisfying SSA criteria, received accolades at the conclusion of my hearing. Both of us arrived, for the appointed time, expecting to argue the issues and no such thing took place. Answering the first question given to me, I finished one sentence and the judge politely skipped to the medical expert for his record of findings. Without further questioning, the ALJ compassionately awarded my disability approval within seconds. Thomas O’Brien’s expert representation won my disability hearing, before it could begin on January 14, 2019. I am still in a joyful state of shock. 3. Equal to O’Brien’s professional value, is that from his Senior Paralegal, Tracy Sugg. Her authenticity sustains in every communication she has with the client. In addition, her compassionate nature never forgets that a client has the right to be innocently clueless ,or scared to death. She replies as if it is her first day in the job and it’s your first day contacting her. Compassionate listening skills from a paralegal means important details (including those to be seemingly unimportant) are given consideration in the transfer of information to your lawyer. These qualities underline the purpose driven skills that Tracy Sugg brings to the mission of your disability case. In my opinion , she obliterates a large number of paralegals into invisible dust. Don’t miss the opportunity of working with this team of caring professionals! I interviewed several firms and nearly gave up believing I would find such law firm. I’m so grateful that I found the attitude I needed to hear, before hiring them. I got every legal expectation I needed and a dreamer’s ALJ Hearing result, for this extremely stigmatized disability.

Extremely Helpful
I went to O'Brien and Feiler Law to help assist me with the Disability process as I am unable to work. I found them by Google searching for lawyers in my local area and they showed up on a big list. I narrowed it down based on reviews and feedback from Google and also this site Avvo. I reached out and had a consultation with Thomas and Tracy which was about an hour. Dealing with enough issues personally the process can seem very stressful on top of that to file a claim with Social Security. Based on the meeting I felt very good about them and got a great vibe that they do really care to help people who really need assistance based on their disability. They are very transparent about what to expect through every step of the entire process from start to finish and what you need to expect and do on your end and what they also do on their end. Throughout the entire process they made it very smooth and were always so easy to do business with. Also Tracy was there every time I would email on any question or needing help with paperwork she would always reply very quick and efficient to assist with any issue I had. I strongly recommend Thomas O'Brien if you need assistance with your disability case as he does fight for you when you need it most.

The lawyer and staff you will want
I picked them on reviews posted and was not sorry at all. Tracy Sugg and Audrey at the practice are hard working. Tracy will provide you with honest information, her professional wisdom and when needed comfort and support. Most admirable is Tracy's follow through! She gave me honest advice and support through my whole case. I strongly recommend this practice and staff.

Outstanding and Highly Recommended
When I first decided to file for SSDI, everyone told me I needed a lawyer. I had never hired a lawyer before so I asked my parents for advice. They set me up with a disability attorney who was a friend of a family friend. I thought I’d be fine. Unfortunately, a few weeks before my scheduled hearing, this lawyer dropped my case. I panicked. I was abandoned at a critical time. Luckily I came across Thomas O’Brien’s profile on He had a lot of client reviews and they were all excellent. Most importantly, one of the first reviews I read was from a client who had been in my situation and had a favorable outcome (first lawyer dropped the case shortly before the hearing and Thomas O’Brien saved the day). So I called Mr. O’Brien’s office. I spoke with Tracy Sugg, his paralegal. I told her my story. She’s the best. Tracy immediately put me at ease with her compassion, knowledge, thoroughness, and clarity. Most importantly, she expressed confidence in my case, which renewed my confidence that I had lost after my previous attorney had dumped me. So we got to work. First Tracy helped me get a continuance for my hearing. Then Tracy and her coworker, Siana, worked with me to gather all of my medical records from my various doctors (no small task!). The medical records form the bulk of any case, so this evidence gathering is extremely important. I am very grateful for the hard work Tracy and Siana did on my behalf. I felt well taken care of every step of the way. Whenever I called Mr. O’Brien, Tracy, or Siana, they would either pick up or return my call promptly (which is something that didn’t always happen with my first attorney’s office). A few weeks before my new hearing date, Mr. O’Brien prepared me for what kinds of questions the judge would ask. Based on the evidence Tracy and Siana had gathered, Mr. O’Brien reiterated that I had a very strong case. He used this evidence to file a brief with the judge. All of the prep paid off. On the day of the hearing, Mr. O’Brien and I walked into that courtroom 100% ready. Mr. O’Brien couldn’t have presented my case to the judge any better. He is very talented. And I couldn’t have received a better outcome: The judge issued a bench decision in my favor. Bottom line: Thomas O’Brien and his support team (Tracy and Siana) are effective, efficient, professional, thorough, knowledgeable, polite, and compassionate. They're everything you want. If you need a disability attorney, I recommend you give their office a call today.

Thank You!
I had an excellent experience with Mr. O’Brien and his staff. After working as a paralegal for over 25 years I was diagnosed with psoriatic arthritis and then Parkinson’s shortly after. Needless to say it was an incredibly stressful time. But Mr. O’Brien and his paralegal Tracy Sugg took care of all the necessary documentation making it much less stressful and I eventually received a fully favorable ruling. Thank you Mr. O’Brien and Tracy for all hard work and kindness. I could not have had a better attorney.

Excellent, professional, courteous, knowledgeable, and honest. THANK YOU! I am forever grateful.
Excellent! I was in a very bad situation, I filed the case myself and was rejected, then hired an attorney specialized in SSDI. I thought he and his team were take care of it for me. Only, I was surprised by the 1st attorney’s paralegal just 2-3 days before the hearing, he fired me and told me that he can not represent me in the hearing. Was not able to speak with the attorney, nor was provided any specific reasons. I called the court and explained my situation, and was granted continuance, in the mean time was told this is only continuance I was going to get and the judge was not very happy. Call my families and friends for suggestion, and finally found Mr. O’Brien’s information and wonderful reviews. Called the number, spoke with Ms. Tracy Suggs right away, after explained my situation and my conditions. By the way, Ms. Suggs was beyond wonderful, what a sweet heart with lots of love and patience. The case was moved forward, Mr. O’Brien and Ms. Suggs was on top of it, kept me informed, and obtained all necessary documents themselves. I practically did nothing but kept up the doctor’s visits, medicines, rests, and sleeps. Went to hearing few months later and was granted FULLY FAVORABLE decision. Can not ask for better team than Mr. O’Brien and Ms. Suggs, they are prompt, professional, courteous, knowledge, and honest. From initial and repeated denials and fired by my previous attorney, I was fortunate to have a wonderful and excellent team of Mr. O’Brien and Ms. Suggs. They walked me through the process and explained what to expect. I know I owe you more than just say THANK YOU, but from bottom of my heart THANK YOU VERY MUCH. I am forever grateful.

Mr. O'Brien and and his office team was the right choice for me or anyone seeking disability. The granting of disability can be a long process and Tom and Tracy in his office where there for me every step of the way until approval. More importantly they where very detailed in preparing every aspect of my case by...... 1) Gathered medical evidence, submitted it to Social Security, and ensured that it was exhibited. 2) Provided rapid responses to phone or email inquiries. 3) Prepared accurate and timely paperwork and responses to Social Security inquiries. 4) Drafted a comprehensive pre-hearing brief that explained your case to the judge, summarized the evidence, and was sent with enough time for the judge to review before the hearing. 5) Offered clear advocacy and direction when conversing with the judge at the hearing. 6) Provided comprehensive pre-hearing counseling explaining the issues, and what to expect. Many Thanks
