""My husband checked into Sierra in May 2020. He was there about 90 days. They took amazing care of him from start to finish. I was made aware of his treatment, plan and post care daily. Paul was his case manager and I couldn’t have asked from someone else. He was able to get on a level with my husband that assisted his positive outcome. If him or I had any questions on where he was going or the next steps someone would call me back and we would have an answer that same day. Fast forward to a few months ago, I was introduced to a family post care support group and this group of people are so helpful honest and truest care about me. Kelly S runs these groups but take her own approach to know that I am going through a recovery of my own and makes me feel that she actually cares about our loved ones. They are just their clients. We have formed a bond that I wouldn’t imagine could have or would have been started by a “client based” center. This is my family now and I am so happy we found Sierra. I mean the location speaks for itself as knowing how my husband would like to rehab during one of the lowest points of his life.""

""Sierra by the Sea is hands down the best treatment center on the west coast. Not only did the program and faculty give me structure in my life it also saved it. From day 1 everyone I encountered from the medical staff to the kitchen cooks are remarkably professional and they care for each and everyone who walks through those doors. The experience changed my life and saved my marriage. Now I’m 14 months sober and forever grateful to SbtS and I know my family is too. ""

""For me, addiction is not just an individual struggle. It is a family struggle. It impacts everyone around me. Sierra by the Sea helped me to realize this undeniable fact, and continues to help me address it to this day. I can say in all honesty the staff was invested in my recovery from the day I walked in door and continues to be months after I discharged. The alumni meetings and the support counseling available to our families are outstanding. It is a tremendous help to build a network of individuals you can reach out to in times of need. They will be there for you, and in turn, you will want to be there for them. It is truly a rehabilitation facility trying to do things the right way. I cannot recommend it highly enough.""
