About Us

EOSIS provides evidence-based treatment services, tailored to the needs of
the individual, delivered by experienced and certified clinicians across a
network of centers. Together, we bring ever-evolving therapeutic innovation
and leadership, a commitment to quality care, and offering wisdom,
collaboration and excellence in everything we do.

Mission

We are dedicated to meaningfully supporting patients, families, and communities in their recovery from addiction and related mental health disorders.

Vision

By living our mission and values, we set the benchmark for excellence, become the first choice for referral partners, and lead the way in addiction recovery and behavioral health care.

Values

Our culture is grounded in a diverse, patient-centered approach, and based on our core values of respect, accountability, teamwork, integrity, and hope.

Why EOSIS?

In Greek mythology, EOS is the goddess of the dawn. Yet her actions were driven by a curse from Aphrodite — forces beyond her control. This struggle reflects the experience of many of our patients, who feel trapped in destructive patterns that harm themselves and their loved ones. EOSIS represents the promise of a new dawn and is a symbol of hope and renewal.

As a leader in drug and alcohol treatment, EOSIS is guided by philosophies that help us care for the whole person:

Personalized care uniquely tailored to individual needs

Evidence-based therapeutic approaches

Full continuum of high-quality patient care

Sustained healing focused on the whole person
