I had seen Dr. Postma in the past approximately 8 years prior so I had to become a new patient and wait 4 months to be seen for a 3 week episode of nose bleeds. That's a shame on Corewell.

- 5 out of 5 starsReviewed on 7/13/2025
It was apparent that he had looked at my history before meeting with me. It made our conversation more fruitful. I felt he heard my concerns and made the best choice considering the circumstances for moving forward. I hadn't met with Dr. Postma before, but I felt he was clear in his explanation of what my choices were, and I felt he was experienced and knowledgeable and cared about my finding an answer to my concern.

The Dr. was professional and helpful. He explained my questions. I had no problem with him whatsoever. He was even accommodating to my phone which I had to use to start a Zoom call (though I was not on it) for my colleagues at 1:45 p.m. He was very patient.
