Dr. Flannery is top notch in my book. Pleasant and knowledgeable and explains the issues well.
He's a great Dr, cares about his patience.
Very professional Fully explained x-rays Gave plan, that I could understand
Dr. Flannery performed a shoulder replacement surgery on my right shoulder on June 12, 2025 and it's not even been 2 months since the procedure and I already have far better range of motion and far less pain than I did before the surgery. The best part is that my shoulder keeps improving every day! I can't wait to see the progress after another month or two. If anyone is having issues with their shoulder that requires surgery, I highly recommend Dr. Flannery! I was very hesitant and had a lot of concerns and doubts before the surgery, but it was the best decision I have ever made.
Amazing surgeon! Knee is healing better than ever imagined. He was highly recommended for any orthopedic replacement, and i totally agree. Thank you Dr. Flannery
Feeling really well after only three weeks, his suggestions and recommendations were spot on and very helpful. Thank you.
Thank you for answering all my questions. I appreciate you showing me x-rays after surgery. Your talent and kindness is truly appreciated!
Excellent treatment
Had a lot of chuckles at our last meeting, he has gracefully placed Humpty Dumpty back on the wall with a right hip replacement and a left knee replacement, soon to be a right knee replace as well. Arthritis has been hard but Dr. Flannery has blessed my days going forward with healing and pain free living. My trust lies in you and your team at OSMS. God is good and so has been my experience start to finish with all who I have been healed with in Dr. Flannery’s care🙏
