ARCA’s Staff understands the importance of initiating treatment as soon as possible. We have 24 hour informational lines and often times can offer same day intake.

Founded in Science

ARCA utilizes anti-craving medications during the recovery process along with medications to alleviate discomfort during the detoxification process. Ask about Suboxone use for alcoholism and opioid and opiate addiction.

TeleMed Available

ARCA provides confidential and private treatment for our patients with the use of TeleMed. Each location is equipped with a secure system to speak with our team of Doctors.

Clear Communication

We pride ourselves on being transparent about the addiction recovery process. Ask us any question that you have about the process from detox to therapy to treatment in your home environment. We are here to help.
