Dr Mitchell did a great Job with my Dads surgery. He is very patient and compassionate and explained everything thoroughly. My Dad really enjoyed all the time he spent with him before and after the surgery. I highly recommend Dr Mitchell.

Dr. Thon has been with me through multiple shoulder injuries over the last 3 of the 4 years my shoulder has been broken or healing. What I appreciate the most is how knowledgeable and down-to-earth Dr. Thon is. He explains everything clearly—options, risks, recovery timelines—without ever talking down to you or using jargon that leaves you more confused. Eric his PA has been just as caring, consistent and thorough, always ready with answers, follow-up care details, and genuine concern. Cassidy his office assistant has been a steady, calming presence through every appointment, surgery and recovery. See this team has watched me heal so beautifully SEVERAL TIMES just to watch me re-injure myself. Going through multiple injuries and needing surgery is never easy, but Dr. Thon and this team made the process feel manageable and supported every step of the way. They treat you like a person, not just a broken human. Their combination of expertise and genuine kindness is rare, and I’m truly grateful for the care I’ve received. I wouldn’t trust my shoulders—or recommend anyone else—to anyone but Dr. Steven Thon. Exceptional from start to finish. I appreciate the care they have given me.
