I believe we show up best when we have strong, empowered relationships with ourselves and with others. I lean towards a casual, relational and assertive style. I will challenge you while holding a warm and encouraging space for you to explore and process. I truly enjoy working with folks from all walks of life, but especially with couples, groups, and families who may be seen as "non traditional.” I work with folks grappling with newfound ADHD or Autism, those processing family of origin, roommates who want to work through conflict better, trans folks navigating complex family dynamics, and so much more!
As a couples & sex therapist, I work with a variety of concerns such as improving direct communication, rebuilding intimacy, navigating mismatched sexual desire, repair from infidelity, exploring kink & BDSM dynamics with care, opening up one's relationship to polyamory/other consensual non-monogamy configurations, and pelvic and sexual pain.
I'm genuinely excited to be by your side, hold you in all of your complexity, and help you navigate, process, and better understand yourself, your partner, your role in relationship to others, and to help you tap into something deeper and more fulfilling. Email me with any questions or to schedule!
