Starting a private practice gives therapists, counselors, and mental health clinicians the opportunity to shape care around their values, specialty, and ideal client experience. It also brings new responsibilities, from licensing and business setup to therapy practice marketing, documentation, billing, and long-term growth.

This guide walks through the essential decisions and practical steps to help you launch with confidence.
