OUR CULTURE

For every person who seeks treatment at The Grove, we hold a vision for their freedom from addiction and sustained long-term recovery. To lessen the risk of relapse, we integrate the latest advances in addition and behavioral science and evidence-based methodologies of care in all aspects of our care.

We are one of the few addiction treatment centers nationwide who have embraced the proven science of Medication Assisted Treatment to treat defeat opioid, substance, and alcohol use disorders.

We view each person who seeks treatment as a singular, one of a kind individual with a unique history defined by genetics, heredity, nature and life experiences. Thus, rather than “one size fits all” “cookies cutter” treatment modules, our clinicians create customized, individualize, best practice treatment plan for each patient, acutely sensitive to his/her unique needs.

Our goal is for each patients to condole and defeat your addiction, reclaim your sobriety, flourish in recovery, and thrive in your future.
