Our Doctors
Experienced pediatric specialists. Care designed for younger patients. WellTeenMD was founded by two board-certified pediatric gastroenterologists who have spent their careers caring for children, adolescents, young adults, and their families.
We created WellTeenMD because weight management during adolescence and young adulthood requires a different kind of care. Younger patients are still growing and developing, with nutritional and medical needs that are different from those of adults. But the differences aren’t only physical.
Weight can be an especially sensitive issue during these years. Body image, self-esteem, relationships with food, peer experiences, and growing independence can all influence how a young person experiences their weight and approaches treatment. Conversations about weight need to be handled thoughtfully, respectfully, and without judgment.
We believe young people should feel like active participants in their care — not that treatment is something being done to them. Most importantly, our patients aren’t receiving a prescription from a provider they’ll never meet. They have physicians who know them, understand their medical history, follow their progress, and remain involved throughout treatment.

These parents haven’t only benefited from the many resources and advice I’ve provided over the years — they’ve also reported feeling more confident as parents.
