As an athlete, hurting my shoulder was the biggest bummer this summer. Coming to OCC, the staff understood and empathized with my urgency to heal my shoulder the right way and rehab to be back at my full potential. While I’m still in recovery mode, I am grateful for the compassion from OCC’s team.

David Bicanovsky S.

Great Discussion and treatment. No nonsense and prompt.

Corey G.

Great doctor / patient experience. Received a ton of information on what needs to be done with my shoulder.

Stacey R.

Dr Thon has a professional and caring demeanor. He made me feel like I was his only patient of the day. He didn’t rush our appointment and took his time and listened to me and asked several follow up questions. I had a follow up telehealth appointment and still felt I had his undivided attention.
I highly recommend Dr Thon and his office.

bigorygunman

Rotator cuff with 3 acute tears. When Dr. Thon got in the shoulder, it was worse than expected. Dr Thon got it done and rehabilitation will, naturally, take longer than expected. However, looking forward to getting my active life back. I felt totally comfortable with him and everyone i met speaks so highly of his abilities.

Joceslyn J.

Doctor Thon was amazing, but the front office was not very kind. They were so unprofessional. That is no reflection on Doctor Thon and his staff at the Lowry location. He is the most kind and caring doctor I have ever experienced. His team
has made sure that I am provided with the best care. I give him 10 stars, he and his team has gone above and beyond. Thank you for all that you have done for me.

donna M.

Everyone was so helpful and kind from the front desk to the wonderful Dr Thon. They all knew what they needed to do, and did it. So greatful.

Maurice M.

Freedom Of S.

Knowledgeable, friendly and helpful that is OCC. From the tech who checks you in, to every doctor’s assistant and surgeon - 5 stars. If I could give them more, I would.

Jim C.

Dr. Thon explained everything very well. He answered my questions and listened to my concerns. I did not feel rushed. Great experience.

Joyce K.

I was lucky enough to have Dr. Stephen Thon as the on-call emergency surgeon, for a freak accident that resulted in my fractured femur. He answered questions, and explained in detail the surgery that he needed to do. For post surgery visits, he has also been very good with giving updates on my progress (based on x-rays), and patiently has answered any questions we have had....not hurrying through the appt.
Due to his meticulous surgery, I only have 3 small incision scars.....1" or less, with 2 of them barely visible.
He is very pleasant to talk with, and explains everything so you understand everything that he has done, and the potential long-range results.
One of my PT's, while I was in Rehab, commented that if they needed the type of surgery that he specializes in, they would ask for Dr. Thon. I wholeheartedly agree!
My injury may have been an accident, but having Dr. Thon as my surgeon was meant to be, for a great outcome!

Karen H.

From my first visit with Dr. Thon, I was impressed by his compassion, expertise, attentiveness, and care. I had complete confidence in him performing my surgery, which made it all so much easier. He has great bedside manner and is a doctor you can trust.

Brittany

Dr. Thon is a phenomenal physician! I sought his help for issues with my leg alignment. Although I need to go elsewhere, his insight was valuable and greatly appreciated. He took the time to validate my concerns, he did a full overview of my case, and he brainstormed solutions for me. He is by far, one of the kindest docs I have ever worked with. He is decisive yet empathetic. He would be my first pick for an orthopedic doc. You will be in great hands with him... Thanks Dr. Thon, that meant a lot to me.

Victoria G.

I’ve had issues with both of my knees for years and at 20 years old after 5 surgeries l am finally taking the steps to hopefully avoid having a major surgery every year, to feel heard and understood is a great feeling and I’m very thankful to be in Dr. Thons care.

Beth-ann W.

My 80-year-old mother broke her hip and a bone near her knee. Dr. Thon performed the surgery and was great; he kept me apprised every step of the way, explained things without talking down to me, was patient when answering my questions and was always a phone call away. Four months later, after a routine check up, Dr. Thon still called me and gave an update on her condition. If/when I need an orthopedic surgeon, Dr. Thon is the one!

critterlovers

Dr. Thon and his staff are truly caring and show that by their willingness to hear your story. They listen to your peculiar problems with your injury....and the life issues that surround you that especially effect your recovery. Wouldn’t want to be treated by any other facility, or group of people for my hip injury. Thanks for your caring. Jim Ayers

Mike H.

My visit at Dr. Thon's office went extremely well. We were greeted by Ali Vanek. She has a great way of making you feel welcome and comfortable. She answered questions directly. Once she completed her time with us we knew exactly what to expect with our visit with Dr. Thon. The wait before seeing Dr. Thon was very short. As with Ali he attentively listened to me and then mapped out a plan for the treatment of my Left Quadricep Rupture. I could not have had a better visit. I had an MRI later in the day and by 9:00AM the next day he called me to confirm the results of the MRI. He scheduled my surgery for 3 days later. Surgery went well with follow up by Dr. Thon and I am now healing and getting ready for Physical Therapy.
Thank you Ali and Dr. Thon

Ben C.
