David Wiss, MS, RDN, CPT, grew up in Los Angeles, graduating from the University of Southern California with a Bachelor’s Degree in Social Science. He earned a Master’s Degree in Nutrition and Dietetics at California State University, Northridge, and completed training to become a Registered Dietitian Nutritionist (RDN).

His Master’s Thesis “Nutrition and Substance Abuse” was a multisite and multidisciplinary investigation into the special needs of addicts and alcoholics within the Veterans Affairs Healthcare System. Mr. Wiss is also a Certified Personal Trainer through the National Academy of Sports Medicine. Additionally, he is a voting member on the executive committee of the Behavioral Health Nutrition Dietetic Practice Group, and is the Research and Grants Committee Chair for the Los Angeles District of the California Dietetic Association.

Prompted by his extensive research and inspiring case studies, Mr. Wiss discovered that nutrition is a poorly understood and frequently ignored component of treatment during rehabilitation from substance abuse. In 2012, Mr. Wiss founded Nutrition in Recovery and developed a detailed curriculum that provides specialized nutrition services to treatment centers.

Nutrition in Recovery is a mobile private practice located in Los Angeles, California. Treatment services are available for both treatment centers and individuals from Malibu through Santa Monica to the South Bay, as well as east through Beverly Hills, and from West Hollywood to Downtown LA.
