Biography

I am a board-certified endocrinologist at The Ohio State University Wexner Medical Center. I specialize in treating complex endocrine disorders, including diabetes, thyroid disease, and metabolic bone conditions.

My patients can rely on me for comprehensive, compassionate care and clear communication. I collaborate with a multidisciplinary team to develop personalized treatment plans that support long-term health and quality of life.

In addition to my clinical responsibilities, I serve as an associate professor of Internal Medicine at The Ohio State University College of Medicine, where I am passionate about education and advancing endocrine care.

    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.
