Traditional Care vs Diamond Care


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.”

    - Sarah T. Poteet, DDS

  • “It's such a great experience to walk into my doctor's office!”

    I have finally found a doctor that listens to my health concerns and is actively working with me to find solutions. It's such a great experience to walk into my doctor's office - Diamond Physicians - and feel like a *person* instead of a cog in a wheel. Thank you Dr. James!

  • “Diamond is truly an exceptional healthcare concept!”

    My husband and two toddlers have been going to Dr. Lyssy since Nov. 2013. I can't imagine life without such professional, convenient, proactive and preventive care as we receive with the entire Diamond team. We no longer wait hours/days to get into our pediatrician or primary care doctors. Dr. Lyssy is always available to see our kids when they're sick and the office wait time is always ZERO. The level of professional and knowledgeable care he has provided on my health as well has been unprecedented. You arrive to be offered with your choice of organic juice, coffee, or water. Test results are reviewed on a digital screen with as much time as you need to discuss your health. It is truly a luxurious medical experience, with affordable pricing. I would strongly recommend Diamond Luxury Healthcare to anyone.
