Are you feeling stuck in patterns that no longer serve you? Maybe anxiety or OCD is keeping you from living your life in the way that you would most enjoy. Or perhaps you are challenged by losses or life transitions which are difficult to face alone. Having a safe place to express your thoughts and feelings can make a difference.

I became a therapist after seeing the benefits of counseling and art therapy on both personal and professional levels. I’m a licensed professional counselor since 2011 and a board certified art therapist since 2022. I hold a Master’s degree in Transpersonal Counseling Psychology with a concentration in Art Therapy. In addition to my degree, also have significant training in a variety of evidence based treatments, including ERP, CPT, Motivational Interviewing, CAMS and ACT.

My experiences with hospice patients and caregivers, seniors, people in addiction recovery, people in crisis, people struggling with anxiety, trauma, life transitions, cultural and social justice concerns, have inspired me to offer therapy in private practice. In my spare time, I love to cook, sing, hike, and make art.

Many of my clients come to me feeling lost or disconnected from themselves.

It's a profound honor and passion to help my clients learn to trust their own thoughts and feelings, take up more space in their world, and truly feel at home in themselves.
