Finn Asterión (Marcks), MSW


Finn Marcks (he/they) is a queer, trans, nonbinary therapist who believes in providing a safe and affirming, healing environment for people who are hurting. Finn’s main passion is working with transgender/gender non-confirming/gender-expansive clients and those healing from trauma. As a lifelong artist himself, Finn believes creativity can play a role in a person’s healing process. He often uses art, music, writing, and other interests to engage clients in therapeutic practices. 

Finn’s therapeutic lens is shaped by both his lived experiences and his work in LGBTQIA+ education and advocacy, as well as youth residential mental health. Finn uses an integrated, trauma-informed approach that pulls primarily from the Person-Centered Approach and Motivational Interviewing. 

They also utilize tools from CBT, DBT, Polyvagal Theory, and Narrative Therapy. Finn has found these methods most effective when working with clients through traumatic experiences and PTSD, along with issues around sexuality and gender identity. 


From their work in community mental health and youth residential mental health, Finn has extensive experience supporting older teen and young adult clients through the difficult transition into adulthood. Finn works with people who are struggling with Complex Posttraumatic Stress Disorder, Anxiety, Depression, Suicidal Ideation, Domestic Violence, families that struggle with LGBTQIA+ acceptance, and aspects of Neurodiversity. Additionally, Finn has provided education and training within mental health and higher education settings about transgender inclusivity and the specific challenges associated with being LGBTQIA+.


Finn completed his Associate of Arts from Grand Rapids Community College (2015), and both his Bachelor of Arts in Women, Gender and Sexuality Studies, Psychology and LGBTQ Studies (2018) and his Masters of Social Work from Grand Valley State University (2023). Finn has served on the Board of Directors for the GR Trans Foundation since 2018.
