Dr. Harrison is fully aware that our greatest threat to health is sleep deprivation at all ages and the poor dietary habits of the Standard American Diet- “SAD”!   Becoming a “sleep coach consultant” and dietary advocate is every bit as important as creating beautiful smiles. Our mission is to help you achieve the maximum natural health that “Nature” intended. Despite advances in Dentistry, no prosthetic replacement comes close to the form, function, beauty and value of a picture- perfect natural smile. Your teeth are a vital part of our natural health system and are designed to last longer than a lifetime. We help you become healthy, handsome and happy.       

Solving the mysteries of genetics’ and environment’s impact on facial development and health from birth thru maturity to aging demands continuous learning and relentless pursuit of scientific evidence to support treatment decisions. The cutting edge is not AI (artificial intelligence) nor robotic technology, but experience and reasoned thinking.
