As stated earlier, Dr. Brennan took the time to go over my medical history, tests and prescriptions. He highly recommended I see a Rheumatologist again about my other autoimmune disorders. He explained the blood tests he ordered were to find the correct diagnosis of diabetes. He ordered a ultrasound of my thyroid to determine if the nodules were causing my difficulties with swallowing food, a endoscopy didn't see anything to cause them. Dr. Brennan was very upbeat and inspired confidence that he would do what's necessary to regain my health.

So a lot of care explain things in a way that you understand and gives you hope for future for the better
