    Hello, I’m Dr. Anthony Berni and I’m an orthopedic surgeon.

    For me, orthopedics fits my personality. It kind of combines a technical, mechanical type of a solution to human suffering, if you will. I can use those skills that I have acquired to allow people to return to a better function, a more normal function and more importantly, relieve their suffering, their pain.

    I actually, in 2005, had a ski accident where I broke my lower leg and had to have surgery out in Utah and that was a good experience for me to reconnect with the patient experience. It’s one thing to be on this side of it where you’re the “doer” and it’s another to be on the “do-ee” side of it where you’re having something done to you. It’s comforting to know that you got a real human being on the other end that understands and understands that you’re nervous.

    I think people feel comfortable when you sit down to them and talk to them and you show them a model. I typically show every one of my patients: here’s exactly what we put in, here’s exactly what we do. People have misconceptions too. That’s the other thing that you need to dispel.

    I treat every single person that comes in here like you’re a family member. We’re going to tell you what we’re doing, we’re going to do our very, very best job each and every time. And half the success is me getting in there correctly and half the success is you rehabbing and doing things correctly post-operatively and we’re going to have a good outcome.
