(they/them)

We are all worthy of dignity, safety, and belonging. 

My name is Sionainn Marissa (you can call me Sionainn OR Marissa) and I am a Licensed Mental Health Counselor in the state of Washington (LMHC), an AASECT Certified Sex Therapist (CST), and a Nationally Certified Counselor (NCC). I am a non-binary, neuroqueer, kinky, and queer, Animist, Pagan, practitioner of magic, who lives with chronic pain and disability. Given these lived experiences, I have felt the impact of intersectional marginalization. As a white person, I do my best to be aware of my own privilege and biases as part of dominant euro-centric descendant culture. I endeavor to do my best to do anti-oppression work that is trauma aware as I believe every person deserves to enjoy their life free from shame and oppression. I strive for cultural humility, and to be an accomplice in the continued fight against white supremacy wherever I can.

I became a sex therapist because I enjoy working with clients who desire more satisfying, fulfilling, and shame-free sex lives. I find it particularly rewarding to help folx who are sexually marginalized included but not limited to kinky folx, disabled and/or chronically ill folx, fat folx, those who are exploring their gender and/or sexual orientation.

As an Autistic person I have deeply rooted special interests, and as someone with ADHD I gather new interests whenever something pulls my attention. I am an artist, performer, avid gardener, nerd and occultist. I am a dog Mom and a plant parent, and have a particular love of carnivorous, poisonous, entheogenic plants, and fungi.

I do my best work with folx who wish to work through their sexual difficulties and disappointments, those who have experienced trauma or have been negatively affected by relational abuse or toxicity, and those who are working to move past shame that has been reinforced by outside sources such as family, religion, or other societal or cultural pressures are welcome. 

As of February 2024 I am officially trained in EMDR.
