Welcome to Colorado. I grew up here but lived in Dallas and Austin for 13 years so I can relate to making the move.
My son's pediatrician is wonderful. His name is Jason Kalan and he works at Childfirst Pediatrics ###-###-####, press 2 to reach a human right away). He absolutely loves kids. His partner (they back each other up) does also. The staff in the office, the nurses and the PAs are all terrific. They aren't exactly in your area but they're very close and worth the extra five minutes. The office is on Yosemite just north of County Line. Exact address: 7336 S. Yosemite St., Ste. 200, Englewood, CO, 80112.
You can interview Dr. Kalan at no charge to see if you like him. You might also want to meet Dr. Kaplan to see if you and your kids click more with him. Both will meet with you for a few minutes. Oh, I almost forgot Megan, the P.A. She is amazing. My son loves her. Good luck!
