I am devastated that Dr. O’Brien is retiring. He is BY FAR the best physician I have ever had in my entire life. His knowledge, listening skills, clear but concise explanations and overall kind demeanor are an outstanding combination of skills. His retirement is a huge loss to the medical community.

Dr O’Brian took the time to explain what I needed to do to help myself. He let me tell him the problem and then explained what I needed to do. Taking the time with the patient is so important.
