College and early adulthood can feel exciting and overwhelming at the same time. I work with college students and young adults who are navigating academic pressure, shifting friendships, family expectations, dating, and big life decisions.

Whether you’re struggling with burnout, identity questions, or just trying to figure out your next step, therapy can be a place to slow down and actually breathe.
