Dr. Duggan was very understanding on what's going on. To be exact he order for me to get a mri to make sure he would no the exact problem without guessing I felt comfortable and would refer him to others.

I began seeing Dr. Duggan in June 2022, after seeing 3 other Orthopedic doctors @ Scott & White and Advent. Dr. Duggan was the only one who I felt listened to my issues that I had, after having microfracture surgery 8 years prior, through another doctor. He saw what "could be" the issue, suggested orthoscopic surgery to clean it up...he warned me beforehand that it might not fix it, but he would certainly try. After a 6 week recovery and 5 weeks of shots, I can safely say that he has worked wonders! He and his staff are most friendly and approachable and I feel very comfortable and secure as their patient. Dr. Duggan and his office staff will be my orthopedic go to in the future, when it's finally time for my knee replacement. I can not thank them enough for helping me become "normal" again!

I was under Dr. Dugan's care from March 2020 to December 2020 for torn shoulder rotator cuff and he is the best. Very considerate and professional.

Doctor Duggan explained my issues and plans of treatment so that I understand what needs to be done. He had his staff made the necessary referrals to get me on my way to the relief I need. I feel that he cares and I am not just another patient he has to deal with. Everyone in the office is professional, friendly, and courteous.
