Oasis Treatment Centers

Oasis Treatment Centers offers detox, residential, outpatient, and sober living care in sunny Costa Mesa for individuals struggling with a range of behavioral health challenges, including any substance use disorders, depression, anxiety, trauma, and other co-occurring mental health conditions.
Oasis welcomes adults for treatment, regardless of whether they live in California. They host 12 clients at a time.
Oasis uses evidence-based therapies, such as cognitive-behavioral therapy (CBT), dialectical behavior therapy (DBT), and mindfulness practices, with medication-assisted treatment and awareness of the interaction of the mind, body, and spirit. They use eye movement desensitization and reprocessing to help individuals heal from traumatic events. Their treatment addresses primary and co-occurring conditions at the same time to provide whole-person care.
Oasis' treatment of marijuana addiction sets them apart from most other treatment centers.
The focus of Oasis' therapy is group therapy, but clients also meet weekly 1-on-1 with a counselor.
Oasis Treatment Centers operates 24/7 and can admit clients day or night. They often do admit clients late at night.
Detox and residential treatment last 30 days. Their day, intensive outpatient program (IOP), standard outpatient therapy, and sober living can last 3 months to a year, depending on the client's needs.
Day treatment lasts 6 to 8 hours each day.
The IOP program can meet during the day or from 6 to 9 p.m., based on which times is better for the clients. It meets 9-12 hours a week.
Their sober living options serve clients who completed residential or outpatient care. Clients receive a house with 5 housemates. Oasis transports clients from the sober living houses to their center for group therapy meetings.
The expert team of clinicians and counselors develop customized treatment plans that empower patients with practical tools for long-term recovery. Their leadership team includes case managers, a licensed marriage and family therapist, an associate marriage and family therapist, and a speech-language pathologist. A specialty of this team is treating clients with post-traumatic stress disorder (PTSD). Oasis employs a 2:1 client to clinical team ratio.
Clients can meet onsite for continuing support in their recovery, and Oasis serves them a free lunch.
