After 10 years as a school social worker in St. Louis, I know what it looks like when people are overwhelmed, and what it actually takes to move through it. Today I work with adults navigating similar territory: the pressure that builds quietly, the transitions that feel harder than expected, the moments in relationships that leave you stuck. My focus is on making therapy practical, grounded, and worth your time.
