"Dr. Berni has been my orthopedic doctor for over eight years. He has treated me for pain in various joints due to osteoarthritis. He patiently listens to my ailments then explores the best options for treatment. Recently I required total knee replacement surgery, and he did a world-class job. At six weeks post-op, I am walking normally and, except for a little lingering discomfort at night, I am pain free!"
