Matthew Nonoshita, CADC-II, RAS-II, CATC – Program Director

During his journey of personal recovery which started in 2010, Matt Nonoshita has worked alongside leading professionals to cultivate his knowledge and experience, while assisting countless others on their own paths to sobriety.   As a member of the California Consortium of Drug and Alcohol Educators and the California Certification Board of Alcohol & Drug Counselors, Matt has continued to strive toward professional growth, acquiring his Certified Alcohol and Drug Counselor-II, Registered Addiction Specialist-II, and Certified Addiction Treatment Counselor credentials.  Due to the increasing prevalence of the nation’s addiction and opioid crisis, Matt works tirelessly to understand the underlying issues of individuals in recovery through knowledge and understanding of Dual Diagnosis treatment. To that end, Matt works to foster a balanced approach to recovery through experiential and recreational therapy including the creation of a Surf Therapy program which combines his passions for the outdoors as well as spiritual growth.  Matt’s extensive experience has solidified the knowledge that the damage created by alcoholism and addiction are not exclusive to the individual, but drastically affect the family and friends of those who suffer. Consequently, his approach to recovery includes educating families on healthy boundaries, crisis management, and codependency. Matt’s dedication to his personal recovery manifests in his family relationships, with his children, his fellowship, and his friends.  He believes in the therapeutic and rehabilitative value of music, of consistently extending a hand to those who struggle, and of the spiritual balance he finds in the amazing geographical context specific to Southern California.
