Kylin A. Jewell

Kylin has 10 years of experience serving Southern Arizona in the Behavioral Health field with work for agencies like PSA Art Awakenings and Intermountain Centers for Human Development. Kylin has been with Catalina Behavioral Health since February of 2024. She has a background in study of Art Therapy from the School of the Art Institute of Chicago.

She completed a minor in Psychology and Bachelor’s of Arts from the University of Arizona with an emphasis in two-dimensional design in 2010. Additionally, Kylin has her 200hr YTT and will incorporate this into her groups if clients are open to engaging in yoga and meditation practices.

In her work with clients, she incorporates relational, person-centered, existential, and mindfulness approaches. By allowing sessions to be client-led and sometimes art-informed, Kylin encourages those she works with to notice themselves and guides them to their own solutions.

For Kylin, operating from a person-centered and existential theory means paying critical attention to the stories clients feel inclined to share and the personal meaning that these stories hold for them. What is important and recurring for the client informs what happens in subsequent sessions. Kylin brings a sense of play into sessions, when appropriate, hoping that she can share her joy and trust in art practice with all who cross her path.
