Always takes the time and listens to your concerns, very thorough. I am lucky to have him as a doctor he has changed my life for the better. I’m more mobile now.
I recently had my 3rd surgery with Dr Flannery which was knee replacement. Other two were hip replacements. All three surgeries went well. He explains everything very well and is very pleasant to work with in addition to performing surgery well.
Always a great encounter.
