Alyssa Cockerline, PA-C

I graduated with a Masters of Medical Science in Physician Assistant Studies from the University of Missouri – Kansas City, and prior to that, with a Bachelors of Health Sciences from the University of Missouri – Columbia (Mizzou). Although I was born and raised in Missouri, I moved to Colorado immediately after completion of PA school, and I now call Colorado home.

I am passionate about treating each child as the individual person that they are. I strive to meet each child’s individual needs through compassion, understanding, and shared decision making. I truly believe that knowledge is power, therefore I try to educate every single patient, and their family, to the best of my ability.

Working as a Pediatric PA has been my dream for a very long time. Here at Castle Rock Pediatrics, I have found my home. Serving this community is not a “job,” but what gets me up in the morning. In my free time I love to practice yoga, hike, camp, garden and trying new things!
