I find myself naturally working with queer and male-identifying individuals who are seeking to reclaim the pieces of themselves that anxiety, depression, trauma, and dependency have robbed. I am here to help you find closure for the life events you likely did not consent to, transforming "unfinished stories" into a foundation for your future. I provide a sex-positive, trans-affirming space that welcomes all genders and sexual orientations. I honor all romantic dynamics, ranging from monogamy to polyamory.
I’m a trauma-informed clinician curious about how your past shapes your present. Together, we use our therapeutic work as a laboratory for change, helping your life take on new meaning. With dual LSW/LCADC licensure in PA and NJ, I support clients across the spectrum of mental health and recovery. Let’s turn your vulnerabilities into your greatest agency.
I believe our relationship is just as real as the others. We’ll explore your history and the defenses that helped you survive. As trust grows, we’ll uncover avoided feelings where deeper work begins. My hope is for you to speak about yourself with less judgment and more freedom, feeling more fully than ever before. I’m excited to connect with you!

I practice from a relational, psychodynamic, and humanistic perspective, with deep investment in the therapeutic relationship as a catalyst for change. I'm curious about how past and present relationships have influenced your entry into therapy, and the impact this may have on your future wellness. I'm DBT-informed and can offer grounding and coping skills when needed, upon your request.
