Best of the best!.....Awesome staff and Mr. McGuire was just perfect. Was professional, considerate, empathic and kind. He answered questions and treated me with respect. When you go through this process, along the way many people forget that you too once held a professional position in the work industry and you are treated less than. This did not happen once with this Law Firm. I would recommend them to anyone whom is attempting to navigate the Social Security. Let me not forget to mention his awesome Paralegal Steve:)

During this long process in my application for SSDI, my attorney was very responsive and reassuring. During my hearing he was very knowledgeable, helpful, confident and calming when I was so very nervous. I would definitely recommend Peter McGuire! Even the admin assistant at the front desk was very helpful as well. ★★★★★ - Posted June 11, 2018

I hired Peter McGuire for disability case. During the process I became sick and was in the hospital and unable to send out the paperwork but luckily they kept in contact with me and made sure I got everything done. I was approved but they thought I was disabled way longer and so Peter took it to a judge . He appeared with me on my court date and made me feel comfortable as he asked me questions and represented me to the fullest. He did a great job and I thank him for his service for helping me with my case. I’d recommend him to anybody that needs a disability claim help.
