Brett Gorby

With years of experience helping people in very difficult circumstances, I have learned that everyone can heal if they want to in that moment. I work with couples, adults and teens that are having difficulty processing their anger, depression, anxiety and trauma. I have a unique approach to helping my clients reach their personal goals through work and self-honesty. There is never any judgment nor expectations other than to help my client be the best version of themselves.
