“I had full ACL surgery a year ago here and the entire pre-surgery, surgery, and aftercare was incredible. I had to wait about a month for my surgery following my injury but I knew I wanted the best and was willing to wait. Dr. Trumper was amazing and did such a good job”

“I have been a patient of several physicians at OCR, on the whole, they are competent and caring. Today, I had the privilege of seeing Rocci Trumper (again). He may or may not be able to help me but most importantly he made me feel like I mattered. Thank you, Rocci!”

“I had both of my knees replaced by Dr. Trumper and I couldn't be happier. Did not figure I would see much of him and was surprised how often he saw me on my follow ups. I would go back if I needed any orthopedic surgery. I have and would recommend him."

“If you are an athlete, you will never find anyone better than Dr. Trumper. He is the only doctor that I have ever seen that will focus on getting you back to full health where you can compete again. If you want your knees to recover, and you are willing to work hard to get there, he is your man.”
