Marissa Mateer

Clinical Social Work/Therapist, LCSW
Accepting clients Last Updated 6 days ago

I specialize in working with late teens (16+) and adults navigating the transition into independence, identity, and adulthood. This stage of life can feel overwhelming—whether you're managing anxiety, adjusting to college or post-grad life, struggling with relationships, or feeling stuck in uncertainty about your next steps. Many of my clients are high-functioning but internally overwhelmed—balancing expectations, pressure, and major life changes while trying to figure out who they are and what they want. I provide a supportive space to slow things down, build insight, and develop practical tools to aid you in your journey. I strongly believe that we must take time to nurture our emotional and mental well being just as we do with our physical being.
