Margaret Piper, PhD
My name is Dr. Margaret (“Maggie”) Piper and I was born and raised in Miami, FL. I grew up playing competitive soccer and went on to play collegiately at Texas Tech University in Lubbock, TX. After my freshman year, I left the collegiate sports world and went onto build my identity and passions in other areas of life–including psychology.
My experiences as a Division I student-athlete and navigating a world driven by diet culture and the thin ideal largely shaped my desire to dive into the counseling world with a focus on eating disorders.
I have lived in Colorado for three years with my partner and our dogs (Dexter and Mabel—you will see them throughout the website and sometimes as guest appearances in the background of a telehealth session). Hiking, winter sports, cooking for friends, DIY projects, exploring Denver’s coffee shops and music venues, reading, and trying to keep plant children thriving, are what keep me energized and fulfilled.

I am currently licensed to practice in California and Colorado.
I have experience and training in Art therapy, Cognitive Behavioral Therapy (CBT), Dialectical Behavioral Therapy (DBT), Acceptance and Commitment Therapy (ACT), and more. Together, we will use these theories in session to look at your personal goals, uncover which pieces work for you, and leave the rest on the shelf.I always treat body image and eating disorders from a Heath At Every Size lens- accepting all bodies and providing education on how body size is not a functional determination of health or disorder.
I am currently training as a Certified ADHD Professional (ADHD-CCSP).On a normal day, I practice my humanness— trying to make room for self-care, walking with my aging pup, exploring new places with my partner, changing my hair color, or making messes with art and home projects.
