Meet Dr. Leonard T. Fazio


Dr. Leonard T. Fazio's journey in dentistry is both unique and inspiring.

His dedication to finding a healthier approach for both himself and his patients led him to become an expert in mercury-safe dental practices.

Trained by Dr. Hal Huggins, DDS, MS, in mercury-safe amalgam-removal protocols, Dr. Fazio's transformation has not only benefited his own health but has also profoundly impacted the way he practices dentistry. He is passionate about providing mercury-free and mercury-safe treatments, ensuring a healthier dental experience for his patients.
