Practice Philosophy

“It’s a privilege to take care of people in this community. I believe an active lifestyle is a healthy lifestyle. My mission is to keep patients active in their work, their sports and their activities.”

“Through my collegial relationship with Dr. Ferdinand Liotta, we started a medical exchange program with orthopedists and other medical personnel in Bariloche, Argentina. For the last 17 years, we have brought education and medical equipment to aid in the care of the people of Argentina.”
