Hi, I'm Heather! As a counselor, I aim to bring lived experience and evidenced-based approaches together - deviating from "therapy speak" to help you find solutions in your own words. I can help you reinvent your personal narrative after experiencing trauma or grief, build a foundation to cope with depression or anxiety, or coach you through life transitions or identity exploration. I want to support you in becoming the best version of yourself in a way that is authentic to your needs, wants, and strengths.

I earned my master’s degree in mental health counseling from Cambridge College. My work is grounded in building strong therapeutic relationships rooted in openness, trust, and respect. I have experience supporting individuals across the LGBTQ+ spectrum, as well as parents and adolescents seeking affirming care.

My goal is to walk alongside you as you identify, name, and work through the challenges you are facing. I am happy to connect with prospective clients and invite you to schedule a free 15-minute phone consultation to begin discussing your needs, goals, and strengths.
