“Derek Merman is a consummate professional, he communicated with us at every turn and treated us with dignity and respect. Mr. Merman always took the time to listen and explained every step of the way. Mr. Merman and/or his staff was always on hand to answer any questions we had or supply us with information. We always felt like we were a part of the process. Our case was handled with the utmost satisfaction and I recommend Derek Merman to everyone in need of legal services.”


“It is rare to find good attorneys these days, so I considered my self extremely fortunate to have been referred to Derek to help me get through a very rough accident claim. He epitomizes the definition of professionalism. I knew when he said he would take care of it or me, he meant it…because he did at every turn. He has since become my personal friend and an adviser I have come to respect and appreciate. He has represented me and my oldest son on two separate cases. I highly recommend Derek Merman for your legal needs.”

"My name is David Morris, I've known Derek Merman for almost 15 years. We went to law school together, and he's always been one of the smartest, hardest working, and most loyal people that I've known which are great qualities to have in an attorney. I know that if something were to happen to me, I would trust Derek to represent my family."
