Feeling confused, depressed, lost, overwhelmed, or frustrated? If you are tired of unhelpful patterns or find yourself asking, “Is this all there is?”... Welcome! Many individuals seek therapy when feeling burnt out and asking themselves existential questions. As a trauma-informed, LGBTQ+ affirming clinician, I focus on delivering compassionate, culturally responsive care. My approach uses various evidence-based practices, including CBT, DBT, ACT, motivational interviewing, psychodynamic, and mindfulness techniques. I will join you as an empathic witness and partner in developing goals to create meaningful change in your life.
I offer individual and group therapy to adults, adolescents, and children experiencing depression, anxiety, PTSD and trauma, ADHD, grief, OCD, emotional regulation issues, relationship problems, and substance misuse. I have experience helping clients with stress management, coping skills, communication, self-worth, identity issues, boundaries, and more.
My goal is to support clients on their journey of self-discovery. Change and transformation can be hard, yet staying stuck and disconnected brings its own suffering. I believe it's never too late to change; after all, it is essential to our growth. When life feels like it is falling apart, it is an opportunity to begin again. You don’t have to do it alone.
