Upon graduation from the University of Toronto School of Dentistry in 1982, Dr. Camastra came to Oshawa and has been practicing dentistry here ever since. “In fact, many of my patients and staff have been with me from the very beginning, which gives me great personal satisfaction.”

“Providing my patients with the best possible dental care is not only my profession, but my passion. Through continuing education, I continually strive to keep up with advances in general and cosmetic dental technology, enabling me and my team to offer my patients the most effective treatment options available. Most recently, I have attended advanced courses in Dental Implants, as well as in LASER Dentistry, so my patients have access to all the benefits of these cutting edge technologies. My commitment as a dentist has always been to help my patients achieve and maintain the smile they desire, thus enhancing their health and quality of life. Through observing my professional satisfaction, my sons were inspired to pursue dental careers as well, and I can’t tell you the great pride and joy I feel to now have them working by my side and my daughter, a chiropractor, working just down the street.

In his free time, Dr. Camastra enjoys traveling, keeping fit and active with running, snowboarding and water sports, as well as spending time with his wife and their family. Check out Al’s office interview video here!
