Patient Reviews

Nov 21, 2023

My family has used Dr Brennan's services in the past. We think he's the best. I recently had arthroscopic surgery on a torn meniscus. He informed me of ALL my options before the surgery and I was treated very well. I was seen in a timely manner and my surgery went off without a single problem. He has a great bedside manner and I would definitely go to him again.
