Dr. Brennan is 100% excellent. Takes time to explain the pros and cons of treatment options. He is very understandable in his explanation. I wish more docs were as excellent as Dr. Brennan is. Thank You Marilyn Mercogliano

Dr. Brennan is one of the most skilled orthopedic surgeons. He did an amazing job on my knee. Plus he is one of the nicest kindest doctor you will ever meet

The entire staff at Orthopedic Associates of Long Island was very professional and answered all questions. I would recommend them to anyone looking for an orthopedist.
