Kristin Thom LCSW, Admissions Coordinator

Born and raised in Wisconsin , Kristin moved to Colorado after spending over 20 years in the Chicago area. She earned her Bachelor’s Degree in Political Science from the University of Wisconsin- Milwaukee and her Masters Degree in Social Work from Aurora University.

Kristin is a Licensed Clinical Social Worker with an extensive background in mental health including crisis intervention, assessments, verbal de-escalation training, inpatient clinical experience, and private practice.

Kelsie Foster MA, Art Therapist

Kelsie came to Colorado from the Finger Lakes region of New York. It was back in upstate New York where she earned her bachelor’s degree in New Media Design. Kelsie then received her master’s degree in Mental Health Counseling with a concentration in Transpersonal Art Therapy from Naropa University in Boulder, CO.

Kelsie utilizes empathy, mindfulness, and expressive arts while working with clients. At Fire Mountain, Kelsie guides the teenagers in creating art focused on the process rather than the product. With art therapy, the purpose is not always to make beautiful creations, but more so to heighten self-understanding, bring out personal meaning, and give an opportunity to release catharsis in a healthy manner. 

She has experience running art-based Dialectical-Behavior Therapy groups with teenagers and adults, applying art therapeutic approaches with all ages of the grief and loss population, and working as an art therapist with teenagers in residential treatment. To have a work-life balance, Kelsie makes time to get outdoors on the trails, create art, attend live bluegrass music, and spend time with her loved ones, including her dog, Barley.

Tug Levy, Education Director

Tug has always loved connecting with people and understands that helping people connect their lives with meaning and purpose is his true passion. Tug holds a master’s degree in education, and as a professional educator, he taught mostly science, in addition to social studies, health and wellness, and math. He also coached middle school and high school soccer. He believes in an experiential, integrative approach to education. Most of his teaching experience was with students who were from lower socio-economic backgrounds and many who were newly immigrated to the US. Tug has always been drawn to working with “at-risk” youth.

Tug left public education in 2010 and worked for 5 years as a professional mentor in a private, residential treatment program for young men between 18 and 25 years of age, who were struggling to succeed as young adults, often suffering from mood disorder as well as substance and/or screen abuse issues. More recently, Tug spent two years managing Boulder’s Runaway, Homeless Youth program. In these different yet related roles, Tug has gained much knowledge and experience working with people of all walks of life and valuable expertise in working with a variety of significant, often debilitating, personal issues such as anxiety and depression, low self-esteem and motivation issues and addictions. Tug has lived in and around Boulder since 1990, and currently lives at 9000 feet in the mountains west of Boulder. Tug is a volunteer youth hockey coach and serves as president of the all-volunteer Nederland Youth Hockey Association. He enjoys being outdoors recreating, appreciating nature, being a dad, good food, and sports, especially hockey.

All these experiences brought Rebekah to Estes Park for the first time in 2015, where she taught outdoor education at a local camp. After some time away from Estes, she returned to work at Fire Mountain and is now a local resident.  

In her free time, she enjoys hiking, running, camping, traveling to all the National Parks, spending time with friends and family, and doing it all with her trusty sidekick Bear.

She utilizes this experience with Fire Mountain’s own indoor herb garden.
