Her clinical focus includes working with individuals diagnosed with ADHD—particularly those with a late or previously misdiagnosed condition—and she has a strong interest in supporting women with ADHD. She also has training and experience in trauma-informed care and strives to create a safe, empathetic space where clients feel supported in their healing and growth.

Trinity is passionate about counseling because it allows her to hold space for those who need it most, offering empathy and support while helping clients achieve personal growth and meaningful change.
