conditions that both challenge her and offer the gift of a uniquely beautiful perspective on life. She also identifies as a trauma survivor, disabled, neurodivergent, a therapy client/consumer and as a member of the LGBTQ+ community. Some clients have chosen to work with her because they value this lived experience in their therapy process.
