This place is where you want to be if you have a orthpedic injury or sports related ortho injury. I have had 2 surgeries over the past 7 years, and Dr. Dan Pereles performed both. He is a great guy, being an athlete himself, he undertands the need to have your body whole nom atter what the age. He does not mess around, he gets to the root of your injury and repairs the best way he knows how. I had a torn cartilage in my knee and a torn rotator cuff in my shoulder. My knee was 100% after 8 weeks, and my shoulder is about 85% after 6 months and after surgery in Feb of this year, I just signed up for my first triathlon this year, 6 months aftr surgery. Dr. Pereles did a great job. I would highly recommend tehir office to any one!! Roy from Olney, MD
