      from Dominick 5.0 Stars - (2025-03-25)
  • "I am extremely happy with Dr Montana and his physician assistants. I am happy with New York and Blood. It is one of the most organized doctor’s office I have ever been to. Hardly any wait time and everyone is so friendly and helpful. My only negative comment would be that this is the second time I had my internist’s ordered bloodwork drawn, and the A1C was omitted. I don’t know if it is something in the computer because the woman scans it, I also give the paperwork to the woman drawing my blood, but it is omitted."
      from Andrea 5.0 Stars - (2025-03-19)
