About Me


I’m a pediatrician who evaluates and treats children with developmental and behavioral disorders. This includes children with delays in specific areas, attention deficit hyperactivity disorder (ADHD), genetic disorders, learning disorders and autism spectrum disorder (ASD).

In my practice, I collaborate with families. When children are young, that usually means working with parents to understand what they want for their child and developing a plan to help reach those goals. As children get older, I include them in the planning and implementation of their care.

I’ve wanted to be a pediatrician forever! I developed an interest in developmental and behavioral pediatrics in medical school. I liked the idea of helping children grow and change, even if they have some delays.

During my free time, I like to read and hike. I also like visiting historical sites and learning about history. I’m learning to practice meditation.
