Johnnie Aicher
Assistant Director of Operations
Johnnie Aicher
Johnnie is the Assistant Director of Operations at Beginnings Treatment Centers. Johnnie grew up in Southern California and has undergone great struggles in his life since early childhood.  Johnnie’s untreated addiction robbed him of many years of his life.  Today with his sobriety he loves giving back to people and he finally feels that he doesn’t have to wear a mask anymore.  Johnnie knows that by leading a sober life he can put the tough guy stuff away and just finally be himself.  Sobriety keeps him from being complacent and he continues to strive for better things. Johnnie’s greatest gifts are his patience and tolerance.  He loves to work with troubled young people because he can relate to their struggles.  During Johnnies years of using he has seen a lot of death and lost a lot of friends to this disease.  He knows that for an addict continued using will only lead to jail, institution or death.  

Johnnie’s goal when working with clients is to break the revolving door of recovery.  His goal is to not see clients constantly yo-yoing in and out of treatment and sober living.  One of his strengths is that he doesn’t judge others as there is not a lot that people have done that will shock him.  Johnnie believes that he went down such a bad path in life and was placed here in order for people to learn from his story.  His greatest hope is that his experiences will enable other people to learn and make different choices without having to experience everything he went through.  Johnnie is well aware that money cannot make you happy as he grew up with a privileged life.  Johnnie says his greatest blessings today are his sobriety, his freedom, and the people that he considers his family today. Johnnie is very proud to say that his mother has 31 years sober and is his best friend today.

Addiction tore Johnnie and his family apart for many years and now with sobriety he has been able to get his family back.  Everything Johnnie searched for as a child he has now and he would never have it if he and his mother weren’t both sober.  He made bad choices most of his life trying to be part of something or trying to be someone he wasn’t in order to fit in.  The path that Johnnie took ended up taking his freedom away from him.

Today Johnnie says he loves who he is.  He doesn’t act on impulse anymore.  Sobriety has enabled Johnnie to hear the word no and be ok with it.  He says he has learned in life that it no longer a me thing but a we thing. With recovery, he now feels able to get through any traumatic times and daily trials and tribulations. For so long Johnnie said he used to just sit on his problems and make bad choices but now he is able to think things through and live in the solution and not the problem. While everyone who meets Johnnie can see his intelligence and innate abilities it is obvious he could work in so many different fields.  His heart and passion is with helping those in early recovery just as so many reached out to help him in the past.  Johnnie knows the importance of family involvement in recovery and is diligent about staying in touch with families and helping to ease the transition into sober living and then back home again.  For Johnnie this isn’t a business - this is about saving lives.

Beginnings Treatment Centers in Orange County, California is Johnnie’s home and he goes above and beyond to make everyone feel loved and welcome.  Just like a good parent though, Johnnie knows the importance of saying no and setting limits. But he is able to do it in a loving way and teach our clients to learn to set limits for themselves, and to ask for help when needed.
