Meet Our Providers

Dr. Lorri Phipps


I consider it a privilege to care for your child and do so as if he or she were my very own. I have always dreamed of owning my own pediatric practice and in 2017 that dream came true. It’s a practice that operates like one I’d want to take my child to as a parent. One where you can reach a doctor at any time day or night when your child is ill, where the doctor will even come to you because she knows what it’s like to worry about a sick child.

As the President and CEO of Mainstreet Pediatrics, my Big Promise to you is this:
To provide relationship-based primary health care to your children, from a mindset of true caring, in our office, through telemedicine, or in your home, when your family NEEDS it, 24/7/365!
At Mainstreet Pediatrics, our mission is to put the care back in healthcare.

She was appointed Assistant Professor at the University of Colorado School of Medicine (2010 – 2015), and later, the College of Nursing (2015 – 2016) where she was the Program Director of the Pediatric Nurse Practitioner Program just prior to opening Mainstreet Pediatrics. During this time, Lorri also joined the faculty at the University of Arizona (part-time) as an Assistant Professor (2011 – 2018) where she developed and chaired several clinical courses in both the graduate and undergraduate nursing programs.
