OlamideOlamide Ajagbe, MD

I am an assistant professor, pediatric hospitalist, and associate program director for the pediatrics residency program at Upstate Medical University and Upstate Golisano Children’s Hospital in Syracuse, NY.

I’m originally from Lagos, Nigeria and I went to medical school at the Obafemi Awolowo University in Ile-Ife, Osun State in Nigeria. I did my pediatric residency training and chief residency at Nassau University Medical Center in Long Island, NY. I moved to Syracuse after completing chief residency.

My academic interests include graduate medical education, communication in healthcare, diversity and inclusion in medical education and healthcare equity.

I would describe myself as a homebody and I really enjoy reading, history, podcasts, gardening and cooking. I also enjoy traveling and discovering new places. I like to joke that if I hadn’t gone to medical school, my alternate careers would have been teaching history or working as an interior designer.

I’m married and I have 3 children and a dog named Mocha.
