Patient Reviews
May 24, 2026
I could have 'mailed' in my visit. He was in and out in a flash. My questions answered with 'let's wait for the test results'. Suggested an antacid and left. My email with a question went unanswered for a week, then a prescription arrived with no explanation - seems his nurse had responded. She ignored my question as to why a week to provide a 'non-responsive' replay. I have canceled my follow-up. The follow-up was a month away but it seems other patients cancel their appointments too, since I have gotten at least 5 offers of an earlier appointment due to 'new' availability.
