Patient Testimonials

Great provider experience. Very personable and easy to get along with.
– Rick Bradley
Dr Piposar did a great job treating my knee and I am very grateful to him and the surgery staff. My only difficulty in the process was communicating with a scheduler for a first appointment it took days and long holds on the phone to talk with a person. I also was disappointed that I met with a PA rather than with Dr Piposar for the 2 week postoperative visit, only because I would have liked to have talked with the surgeon who did the surgery at this first visit. I would have been fine with a PA meeting with me at the monthly follow up visit. Thank you for your consideration,
– Diane Scully
As a patient of Dr. Piposar I couldn't be happier with the professionalism, respect and care he gave me throughout the process. From the initial meeting to the surgery and the follow up care Dr. Piposar was great. I highly recommend Dr. Piposar
