I'll keep you posted. Initial meet n greet and hiring them as my daughter's representation for our cases went very well. Super knowledgeable, patient, gave excellent explanations of what to expect, professional and yet still friendly in a comfortable atmosphere. Exuded a calm confidence that reassures you that you're in good hands without any annoying pretense. I'm willing to bet I'll be just as happy when our business together has concluded but I'll keep you posted.

Through the long process of a denial on my disability, I started working with Peter i
McGuire. Peter and Megan helped me through the process and I was rendered a favorable decision at my hearing.
I was also given back benefits just days after the hearing.
Thanks Peter.

Mr. McGuire represented my son who is a special needs kiddo and functions below his age level. Mr. Mcguire was understanding, patient and explained all we needed to know for our hearing. His paralegal was also kind and patient with me as I had many questions and called her often. Thank you both for taking a lot of pressure off of me. It is greatfully appreciated.

I retained Pete McGuire and staff to assist me with the disability process. He was able to guide me through until it reached the final court hearing date. I was approved. They made a potentially overwhelming process very tolerable. I am so glad I hired him! Highly recommend!
