🧠 Understanding the Different Mental Health Licenses
Comparing mental health licenses is essential when selecting the right provider. In the U.S., mental health professionals hold different licenses, and many clients struggle to understand their distinctions. Whether you need medication management, therapy, or psychological testing, knowing the differences between psychiatrists, psychologists, therapists, and psychiatric nurse practitioners can help you make an informed decision.
Before diving into the details of each license, it’s important to remember that finding the right provider depends on more than just their credentials.
