Carrie K.
Dr. Argintar is quick and efficient and attentive at the same time. I was brought in before my insurance paperwork was even done! He had clearly read (or had been briefed on) my file and I think I was in and out of there in less than 20 mins from the time I walked in the door. Highly recommend.
Hannah C.
Dr. Argintar, his assistant and the receptionists were incredibly friendly and on-time. I felt heard and listened to, and would highly recommend this office to anyone looking for a professional and personable doctor and team.
Adam A.
Dr. Argintar was quick and to the point. He was able to identify the injury and recommend what I need to do to begin the healing process. He listened to what I had to say and was able to get me out in a timely manner.
Natalie P.
Dr Argintar was very knowledgeable and helped me understand a bit more of what was causing pain. He was open to listening to me and gave great suggestions on what I should be doing to minimize pain. Will definitely see him again for my follow up.
Pamela W.
I was most impressed by Dr Argintar’s understanding and enthusiastic support of my goal of returning to active participation in my sport, though I am an over-50 athlete. Dr Argintar was prompt, direct and took the time to explain my injury and route to recovery. As his patient, I felt respected and informed.
Sean G.
Dr. Argintar was very personable, explained what was going in with my injury, talked me through treatment options, and proposed a treatment plan that worked with my schedule. Great, quick visit.
