About

Video Visit Instructions
I started my career as a hospitalist with Lurie Children’s for 14 years and would take care of premature infants, hospitalized children and manage newborns that needed assistance during deliveries. I then went on to work for a private pediatrician for 8 years before joining the group at Swedish Hospital. I am currently a Certified Breastfeeding Specialist and working toward an IBCLC (Certified Lactation Consultant) by the end of the year.

I like to support families, keep them as healthy as possible, and help children reach their highest potential as an independent adult. I am a mother of 2 children and have personal insight into how important support is during all stages of child development. I enjoy taking care of kids of all age groups and find the various stages as unique as the kids themselves.

We have never seen this doctor before but due to the need for a follow up were able to get an appointment with her. She was wonderful, kind, and really took the time to ask questions and make my son feel better. I would absolutely recommend her.

I had to have a date change for the well child check up. We waited in the office for an hour. The doctor came in telling us she is not supposed to see a new patient on a Saturday. No apology about the delay. She totally rushed through. Not allowed any question.
