I work with people who feel like life is happening to them—those carrying anxiety, depression, or overwhelming stress, still feeling the weight of past experiences or painful relationships, or noticing that old coping patterns like substance use no longer do what they used to. Most of the people I see arrive with a growing sense that something isn't working, and a willingness to try something different. My approach is collaborative, warm, and focused on understanding what's getting in the way and building a path forward together.
