Dr. O'Donnell is always pleasant and easy to talk to.
Dr. O'Donnell is an exceptional endocrinologist - and I have had many over the past 10 years. He is very attentive and really listens to what I have to share without judgment.
I am so happy I was able to see Dr. O'Donnell. He truly feels like a godsend. I've only ever had two doctors in my 37 years of life who have actually listened and validated my health concerns. Dr. O'Donnell is one of those doctors. I can't say enough nice things about him and his professionalism.
I've been seeing Dr O'Donnell for almost 10 years now for thyroid nodules and for two cases of amiodarone induced hyperthyroidism (amiodarone prescribed by electrophysiologists for PVCs and AFib). Dr O'Donnell has always been very thorough in his thyroid examinations and treatments plans, and has been very patient with me and my many questions. My visits with him have been great learning experiences.Dr O'Donnell is a TOP DOCTOR and ENDOCRINOLOGIST and also a great person !

Dr. O'Donnell was awesome. Coming to an appointment to discuss something that's been emotional/uncomfortable- he was very disarming and easy to talk to. You could tell he wants to help his patients. I am excited to continue to work with him.
The provider was listen me carefully and treat me gentle.

The doctor and his assistant doctor took their time and did everything they needed to do to see what was best for what I was there for and went through everything with me and listened to all my concerns and explained everything to me very well to me about my condition and took their time and didn't rush through the visit
Excellent
Doctor was very attentive and listened to what I had to say.
Absolutely LOVED this provider. A Resident saw my first. He was wonderful and explained everything. Dr O'Donnell came in after the Resident. He explained everything in great detail. He offered several options. He laughed and made myself and my husband comfortable.
Great experience
Excellent.
