Patient Reviews

  • "Everyone in the office was warm and welcoming. Dr. Diamond took the time to get to know me as a new patient and answered all of my questions. I believe I am in good hands"
      from Maureen 5.0 Stars - (2025-12-16)
  • "Dr Diamond and the PAs that are there are fantastic !!!!!!! I never have to wait, I get the results instantly. Always a great experience. 5 stars I do have one negative comment the billing department is horrible!!!!!!! I always make my copayment when I have my appointment and I continue to get bills stating that I owe them the copayment. They have put me in collection and I still continue to get bills, even after I sent a copy of the payment receipt to them. You need to hire more competent people to do that job!!! 0 stars"
