Biography

I am a board-certified physician assistant at The Ohio State University Wexner Medical Center. I treat chronic conditions including type 1 and type 2 diabetes, Graves' disease, Hashimoto’s disease, hyperthyroidism and hypothyroidism.

I always provide personalized, high-quality care with compassion, empathy and active listening. When people come to see me, they can expect an evidence-based approach with treatment plans tailored to their individual needs and values. I prioritize shared decision-making with my patients and empower them to take active roles in their care. I aim to be a trusted collaborator on each person’s wellness journey.

I’m proud to work with such an exceptional multidisciplinary team to deliver the best care possible for our patients. I also appreciate the emphasis on medical education here at Ohio State.
