Traditional Care vs Diamond Care

Elevate Your Health with Diamond Physicians

At Diamond Physicians, we do things differently. We're not a traditional practice that waters down patient care in order to keep revenue up. Every patient we see benefits from first-class medical care, minimal wait times, and no co-pay.



  • “Amazing at looking at the entire picture of a person's health!”

    “Dr. Anthony Lyssy and the entire team at Diamond Physicians are tremendous medical partners to work with. As a complete health dentist, I recommend my patients see him because he understands the importance of how the oral health can greatly impact overall health. Dr. Lyssy is amazing at looking at the entire picture of a person's health and discovering root causes of inflammation. Their philosophy of focusing on preventing disease aligns well with my dentalpractice mission. I wish more practitioners had his progressive mind-set and included dentists as a part a collaborative healthcare team. I would highly recommend Dr. Lyssy as a doctor that goes above and beyond to ensure personalized, comprehensive care for his patients.”
