I wish all docs could be as informative and concerned as Dr. O'Donnell. He is timely but never makes you feel rushed. He is one of the best docs I see.

I see Dr. O'Donnell only for my thyroid/hashimoto. He is amazing with all my questions and explaining the answers to me as I am newly diagnosed. He takes his time with the ultrasound to make sure he gets the best results. He doesn't rush through the appointment just to get the next appointment in, he explains, he listens and he answers any and all of my concerns. Dr. O'Donnell is exceptional, knowledgeable, courteous and compassionate.
