I am a therapist because the world can be a hard place to be if you are having a difficult time in it. I am committed to making therapy a productive experience and will help you to understand yourself better.  My clinical interests include addiction and the effect that it can have on you and your loved ones, intimate partner violence, the impact of invalidating caregivers, violence and institutional oppression, mood disorders, depression, anxiety, and life transitions. I have extensive experience working with LGBTQ people and have a particular interest in supporting LGBTQ folks in addiction recovery.
