We started our detox center as a response to the lack of compassion and consistency we saw in addiction treatment. Too often, clients were treated like numbers rather than people, and we knew there had to be a better way. Our mission from day one was to raise the standard of care — combining medical safety with genuine human connection.
Since then, our center has grown into a trusted place for healing, setting a higher benchmark in detox and residential treatment. Today, we continue to build on that foundation, providing a safe, supportive, and professional environment where every client has the opportunity to begin recovery with dignity and hope.
At Renu Healthcare, we are dedicated to helping individuals from all walks of life find lasting recovery from addiction. Our mission is to deliver personalized, holistic care that empowers clients to live a fulfilling, substance-free life.
Renu Healthcare’s addiction treatment center in California is located in the heart of Costa Mesa. Our facilities are brand new built from the ground up and meticulously maintained. We are situated just a ten-minute bike ride from the beach and just a short brisk walk away from our beautiful park. Renu Healthcare provides an oasis of tranquility and comfort for our guests while they embark on their journey to sobriety and health.
