“As a Pediatric Endocrinologist, I partner with my patients in the pursuit of overall health and wellness. I always look forward to building life-long relationships with my patients so that when they grow out of pediatric services they have a strong foundation to continue to successfully manage their health as adults.

Outside of the medical office, I enjoy staying active through playing basketball, exercising at the gym, hiking, and traveling. I also enjoy trying new restaurants and spending time with family and friends.

I look forward to meeting you in our Specialty office.
