Patient Testimonials

Truly a Great Doctor

Dr. Principe has been my third ortho specialist I have been to and I will never go to anyone else ever again. His bed side manner for my two surgeries have been fantastic and has always followed up personally every time I’ve called about a question from recovery. I’ve had doctors at other practices that all they talked about was how happy they were with the surgery came out and the first thing Dr. Principe said to my family after my surgery was how I was doing after my surgery. Truly a great doctor.

Huge Success

I had severe arm trauma from an accident playing sports and I was recommended immediately to Dr. Principe. He did not disappoint. He saw me right away the next day, got me into surgery as soon as he could and the operation was a huge success. I had a faster recovery than I ever could imagine. Dr. Principe was also a pleasure to deal with - courteous and also explained everything I needed to know about the injury, surgery and recovery. I would highly recommend Dr. Principe and his staff at Del Ortho.

Spectacular Doctor

I was super nervous picking an orthopedic specialist since I just moved to the area & I am by far very happy with my choice! Dr. Principe is a spectacular doctor, very honest, & to the point. The office itself is quick, and welcoming. I can’t thank this team enough for being so great!
