Patient Testimonials


Thanks to my care at UOS, I can still use my left arm. After a severe farm equipment accident, I was broken from head to pelvis. Dr. Kostas did a great job putting my shoulder back together, and the follow up care was excellent! I would highly recommend him!

William, Shoulder Surgery

Thanks to my care at UOS, I can ride my horse again without pain after having severely fractured my hip 3 months ago.Thank you, Dr. Kostas and Cassandra Piper, PA-C for your great skill in putting me back together. I am so happy to be walking, riding, working, and dancing again.

Donald, Hip Surgery
