You were prompt in answering questions, available during off-hours, got me in touch with the right doctors and professionals, and I always felt like you were advocating for the “best deal” for me and my family rather than cutting deals with the insurance company for the easy out. I heard from many people that you were the best at what you do and after my experience with your firm, I have no doubt that what I heard is true. You are worth every penny you earned for us.” – James

You took the time to explain in detail what was going on and if you could tell by my voice that I wasn’t understanding, you said it again with an example. You also gave me suggestions which I listened to. I know you’d say you’re doing your job, but there are different ways to do that job. You did it in a caring way.” – Kathy S.

“Unfortunately, I found myself in a position to need a lawyer due to some very bad drivers, several times. The first was after my husband was nearly killed in a car accident and needed to be air-lifted by Flight for Life. I was a new mom and overwhelmed. Pat Dunphy was my lawyer. He was, supportive, honest, knowledgeable, and a good listener. Every issue that came up during my husband’s very long recovery, he handled with ease. Knowing he was in my corner gave me a sense of relief, calmness, and strength in dealing with my husband’s serious accident. He took so much stress off my shoulders. When my husband and I had to do a deposition, we had absolutely no fears, we knew we were prepared and protected. We both highly recommend his firm, they were a godsend several times for us. I would never go anywhere else!” – Joe and Kathy Serak
“Pat, Thanks for your tenacity and work ethic! You consistently exemplified an understanding of what we deemed important on Rial’s quest for justice. Faith, family, honesty, integrity, and truth. God bless you and yours.” – Anonymous Client
