L.A.
First, welcome to the area! :)
For Pediatrician, we use Pediatric Partners (www.doc4kidz) and they're located at I-435 and Quivira. All the docs and NPs there are great, we see Dr. Mellick.
For Family Practice, I use Shawnee Mission Primary Care (shawneemission.org/primarycare) and they're located at I-35 and 75th St. Again, lots of great docs and NPs, good mix of men and women, and they treat a broad age range. I only mention the age thing because when i first moved here i picked a female doctor near my house and even though her bio said she treated all age ranges, she almost exclusively treated geriatrics.
