What patients say
“I saw Dr. Stepanyan about a knee joint recently. When he introduced himself, he asked how l was doing generally. I mentioned a stitched wound and he cleaned and rebandaged it. He also observed another condition I had and set up a treatment for that. And he treated the knee problem effectively. Great competence and service... so gratifying to encounter a professional who is not just "paint by number."”
