Dr. Jennifer Markley

My focus as a pediatrician is looking at the whole child, considering the physical, mental, and social health issues that might affect a child’s growth and development. Moreover, my role is to educate, counsel, and be an advocate and friend to my patients and their parents. As a mother of two children, I understand a parent’s needs and anxieties.

My goal is to be a resource to parents as they raise their children to be happy and healthy. I look forward to being a part of your family.

Dr. Richard Booth

I have always challenged myself professionally, compressing a pediatric residency and a pediatric hematology/oncology fellowship into four years instead of five. In 1976, I returned to Fort Collins and established my solo pediatric practice. My board certifications are from the American Board of Pediatrics and the Pediatric Sub-Board of Hematology/Oncology.
