Alliance Psychiatric Group

About Our Practice

An alliance of clinicians, centered on you

Alliance Psychiatric Group is an organization of experienced psychiatric clinicians with a clear vision: meeting the psychiatric needs of the individual, the family, and the community.

Our Mission

Quality psychiatric care for our community

We are a full-service outpatient practice committed to providing high-quality psychiatric care for children, adolescents, adults, and older adults. Our services include psychiatric evaluations, medication management, addiction treatment, and telehealth care.

Our patient-focused model starts with your needs and builds care through collaboration, so treatment is shaped around you rather than the other way around.

Serving Southern California

We are honored to serve the Southern California community from our office in Lake Forest, in the heart of Orange County. Patients visit us from Irvine, Mission Viejo, Laguna Hills, and surrounding communities — and secure telehealth visits extend our care across California.

How We Practice

The principles behind our care

Patient-centered care

Treatment starts with listening. Our providers take time to understand your history, circumstances, and goals before recommending any plan.

Evidence-based practice

Care decisions are grounded in current clinical evidence — including a commitment to the lowest effective medication doses, used judiciously alongside therapy.

Collaborative treatment

We coordinate with therapists, primary care physicians, families, and other members of your care team so your treatment works as a whole.

Whole-person perspective

Mental health is connected to physical health, lifestyle, and life context. Our providers consider all of it, not just a symptom checklist.

Our Founders

Leadership with decades of clinical experience

Alliance Psychiatric Group was founded by clinicians who remain active in patient care today.
