  Patricia Moomey is a Certified Addictions Treatment Specialist (C.A.T.S.). Her extensive experience in drug and alcohol intervention and rehabilitation give her a unique insight in this field.
Ms. Moomey received training for alcoholism and substance abuse peer helping skills with John Bradshaw in 1984, graduated from Los Angeles Mission College in 1990 and in October 1990 became certified as an interventionist with The Johnson Institute. In July of 1996, she became a grief recovery specialist by The Grief Institute.
Education about addiction is important to Ms. Moomey. As an educator, she has been a speaker for several organizations including:
-Santa Monica College career class on Crisis Intervention

Drug and alcohol intervention is an integral part of Ms. Moomey's practice. A Gallup study of 800 adults in Chemical Dependency Treatment shows that 70% said they stopped after a friend or relative intervened. It is OK to love an addict/alcoholic, but it is NOT OK to allow self-destructive behavior to continue. By helping people reach out to their loved ones, Ms. Moomey hopes to accomplish her goal:
To save lives and restore families.
When do you call an Addictions Specialist?
-Before the addict/alcoholic "hits bottom".
-When you need education and choices around addiction.
-When you are confused about allowing or enabling self-destructive behavior.
-When someone needs help but refuses to accept it.
-When you need to know how and when to set boundaries.
The reasons people fail to call an addictions specialist are many. Maybe they think it's "not that bad" yet, or they fear what others might say or what they might have to do. Still others really don't know who to turn to. For a free consultation and questionnaire to determine if intervention could be considered, please contact Pat Moomey, C.A.T.S. today.
