Dave Eichhorn, LADC, CSAC, ICADC
Clinical Interventionist and Case Manager

Dave began working in the field of addiction in 1991. Prior to becoming a professional in this field, Dave worked through his own struggles with addiction and twenty-eight years ago found a successful way back to living a life drug and alcohol free. It was during in-patient treatment that he began to embrace the life of sobriety through a successful recovery program that he began to understand addiction as a disease and that he wasn’t a bad person.

After completing in-patient treatment he was compelled to maintain this healthy lifestyle that continued to lead him down the right path, so he changed his Major in college and became a clinician that would allow him to obtain the knowledge to help other alcoholics and addicts find their path back.

Dave has worked with every population and has enjoyed every moment of change that has occurred for those that have embraced recovery. He began his career in the treatment world as a clinician and has worked in some of the top treatment centers in the country. In 2002 he made the switch from being the program supervisor at Hazelden to become a clinical Interventionist. Dave was fortunate to be trained by one of the top Interventionists in the country at the time and nearly 2000 interventions later has had the privilege to help the majority of addicts and alcoholics receive the help that they so desperately needed. 

Every Intervention is different and being able to assess the situation in the best possible way to produce the most positive outcome is what he prides himself on. Dave believes that Intervention is not an event; it is a process by which the whole family needs to change to understand what their role has been and then be able to recognize the need to begin doing something different to produce a different result. Through the training and education that Dave provides to and with the family, they are able to go into the intervention with the best plan for themselves and the addict/alcoholic. Intervention is not punitive, it is the most loving and caring action that one can do for their loved one. If the addict/alcoholic could have done this by themselves, it would have happened already. What Dave points out to families is that addiction is the only disease known to man that will keep telling you, you don’t have it. There in lies the need to step up as a family and go through the process of intervention. It is scary for most families to step out of there comfort zone, however when Dave leads the family into this experience, he provides the family with a level of confidence allowing them to walk through it in a safe and healthy way. 

Dave has had the privilege to be nationally and internationally certified as a clinician. He is committed to helping one family at a time by moving them out of the problem and into the solution. The goal is simple; by helping to promote change within the family, moving them into recovery so that they do not have to keep supporting the addiction – not for one more second of one more day. Once the addict/alcoholic begins to realize that things are going to be different it will be the turning point for them to see the need to get some help for themselves.

Dave lives in the suburbs of Twin Cities of Minnesota with his wife, their teen granddaughter, and their rescued Miniature Australian Shepard.  When Dave is not traveling nationally and internationally to perform Interventions; he enjoys spending time with his family, playing golf, listening to 80s music, going to the movies and exploring new restaurants in the Twin Cities.
