Kathy Sheffield, R.D., LMFT

Nutritionist & Eating Behavioralist

Kathy Sheffield is a clinical dietitian and a psychotherapist who specializes in bariatric surgery. She attended University of California at Irvine and California Polytechnic State University, San Luis Obispo, and received a bachelor’s degree in Nutrition, and a Master’s Degree in Nutrition from San Jose State. She has a Master’s degree in Psychology  from Saybrook Graduate School in San Francisco, and has been  licensed as a Marriage and Family Therapist since 2008, with 20 years training prior in family systems theory.  In 25 years as a clinical nutritionist, she worked in inpatient clinical nutrition, weight management, oncology, and wellness, and has been an adjunct faculty member at Sierra College for 20 years.  As an eating behaviorist  working with individuals before and after surgery, Kathy considers not only nutrition, but the many other factors that affect eating, such as patterns and habits that become automatic, emotional eating,  and the impact of personal relationships and life challenges on  eating behavior and motivation.  In this way, coaching is individualized to the person and their life.

At North Valley Surgical, Kathy sees patients for preoperative psychological evaluations, nutrition consultation and teaching, as well as regularly in our aftercare program in the months and years after surgery.  She facilitates our support group and online support group.  Patients in our practice can expect  supportive care with the behavioral, emotional, and nutritional aspects before, during, and  after weight loss, and in the years following.
