About Me

Interested in everything... and nothing else.

— Umberto Eco

Background

I’m a licensed marriage and family therapist, educator, and doctoral researcher with University of Ottawa and Harvard Law School’s Petrie-Flom Center for Health Law Policy, Biotechnology and Bioethics. I was born and raised—mostly— here in Portland, Oregon where I am currently based. I come from a family of creatives and public figures who showed me what it means to be dedicated to craft while holding an ethic of care and service.

Though my my first career was in the arts as an audio-engineer, I am proud to have been in healthcare across disciplines since 2006 beginning as a licensed massage therapist. Even in that role, however, I often found myself serving as a listening ear for people navigating personal challenges. Shifting to psychology felt like a natural next step, and those who know me weren’t surprised.

Friends and colleagues describe me as insatiably curious and deeply passionate about drawing on my personal experiences—navigating complex relationships and continuously exploring what it means to be human. Regardless of whether I am working in my private practice, writing, consulting, or conducting research, I aim to bring about beneficial systemic change. These values are reflected in my work as a therapist and researcher.

My background has given me a deep understanding of the pressures involved in supporting people from all walks of life, especially in the medical care community and those in the public-eye.

Outside the office and research lab, you can find me cooking, connecting with loved ones, enjoying the outdoors, planning travel, sci-fi geeking, and working on being a less insufferable music nerd.

  • I hold a Master’s in Marriage, Couple, and Family Therapy from Lewis and Clark’s Graduate School of Counseling, a program centering systemically oriented, culturally competent clinical training. This approach accounts for the cultural, social, and spiritual issues that shape the whole person.

    In addition to my work as a therapist, I am an active researcher and bioethicist with a second Master of Arts in Bioethics and Science Policy at Duke University. I am currently continuing my research through doctoral study at the University of Ottawa in experimental psychology and psychedelic therapies with Dr. Monnica Williams at her Laboratory for Culture and Mental Health Disparities; and as an associate researcher with Harvard Law School’s Petrie-Flom Center for Health Law Policy, Biotechnology and Bioethics POPLAR project. My research examines topics at the intersection of bioethics, psychedelic-assisted therapy research, and culturally responsive and trauma-informed clinical practice. Alongside my clinical work, I am passionate about advocating for policy reform, offering robust ethics education, and creating psychoeducational materials for clinicians and partners in mental healthcare.

  • I am grounded by systems thinking and I incorporate attachment theory, existential-humanistic, and narrative approaches; this combination places value on relationship and experience as foundational to healing. I am also in process of earning EMDR and Internal Family Systems Therapy certifications.

    Whether you’re seeking therapy for the first time or returning, we will begin by meeting you where you’re at. I am dedicated to approaching each session with curiosity, warmth, compassion, and a willingness to challenge you (gently) when needed while maintaining respect for your unique lived experience.

    As a therapist, I feel honored to regularly witness the transformation that occurs when people retune to themselves through the therapeutic process and I look forward to supporting you.
