I really like our pediatrician, located in Fridley, which isn't too far from the Crystal area, especially given all the freeways between the two suburbs.
It's Fridley Childrens and Teens Medical Center, located right next to Unity Hospital in the Unity Profesional Building on Osborne Road in Fridley. We usually see Dr. Jill Funk. I think she's fabulous! There are several peds. there, all of whom have been wonderful with our two young boys. Phone number ###-###-####. They even have a walk-in time on weekends and holidays, which is perfect for those inconvenient fevers and ear infections that seem to pop up after business hours!
Good luck! Hope this might help you in finding a new pediatrician!
