"I really like Dr. Brennan and NP Collins. However, 2023 has been a series of canceled appointments and horrible missteps in the beaurocracy between the lab, getting information to the medical practitioners... This office is grossly understaffed"

"I was very impressed with the the way he spent time with me and explained in detail about the issue and examination including the test..."
