Dr O’Sullivan is always positive and encouraging. He is THE BEST!
Very professional and personable. He explained points about my follow thru with physical therapy, and importance of that. I like him and his demeanor.
Excellent surgeon. He cares about his patients. He listens carefully and is super thorough. Highly recommended. Thank you Micheal, for your amazing care.
Great provider to work with. Always gives time to listen to what is hurting, how to help and what is future needs.
He is very easy to talk to and listens to all my concerns. This was my second visit with him and I am hopefully having my hip surgery in December.
Awesome!
Doctor O’Sullivan did such a great job on my first knee it was a no-brainer to have him replaced the second knee.
Very relatable guy.
Personable and knowledgeable
He takes the time to explain all you need to know about the surgery and what to do after.
