Precision's process

We begin our process with a thorough and comprehensive initial assessment completed by a prescriber or a therapist.

We take the time to understand each patient's unique history, needs, and goals. We then work in a collaborative fashion with the patient to craft an individualized treatment plan. During the course of a patient's care, our team of specialists continues to assess progress, obtain further information, and adjust treatment recommendations. We empower our patients by involving them in their care and providing education, ensuring they have the necessary information and resources needed as they make decisions about their psychiatric care.
