Donald Erwin, Ph.D., who is the Clinical Director of Monmouth Psychological Associates' Eating Disorder Program, received his Bachelor Degree in Psychology from Harvard University in 1970, and then spent a year in research at the Massachusetts General Hospital in Boston. Dr. Erwin went on to Brandeis University to get his Master's and Doctorate degrees, and did his doctoral research at Oxford University as a Sachar International Fellow. After getting his Ph.D., he was involved in a post-doctoral training program, Lifespan Developmental Psychology, at the Duke Medical Center in Durham, North Carolina. Dr. Erwin has been working with eating disorders for 35 years, and has been active in a variety of professional and consumer-oriented organizations. He founded the NJ Chapter of the American Anorexia/Bulimia Association in 1990 after serving on the Board of the national organization for a number of years. He has been President of the Mental Health Association of Monmouth County and the Monmouth-Ocean County Psychological Association. He is a frequent speaker at conferences and workshops in New Jersey, and often is asked to do Eating Disorders prevention and awareness programs in schools. He was also on the faculty of Hahneman Medical School and is a Clinical Supervisor in the Applied Psychology Program at Rutgers University. While Dr. Erwin agrees that he has been fortunate to have some very good opportunities for academic training, he would maintain that he has learned the most from his patients over his years of practice. He feels that his primary focus in the treatment of an eating disorder is in helping his patients understand what is behind their troubled relationships with food and their bodies. He is open and direct in his counseling techniques, and sees his work to be collaboration with his patients to remove the eating disorder from their lives. Dr. Erwin lives close to his practice, and likes to spend his time off with his family taking hiking and camping trips.

Elizabeth Ebner, M.S., R.D., a clinical nutritionist at Monmouth Psychological Associates, received her Bachelor degree from Rutgers University with a double major in Biochemistry and Nutritional Science. Liz completed her Masters degree program at Texas A&M University in Nutritional Biochemistry, and began an intensive year-long dietetic internship at Texas A&M affiliates, which she completed in 1992. Her Master's Thesis was a study devoted to weight management in obese and non-obese females, and was published in the Journal of the American Dietetic Association in March 1992. Liz has been working with clients in the Eating Disorders Program at Monmouth Psychological Associates for almost eight years. Prior to coming to this program, she worked for two years for Diabetes Treatment Centers of America. She currently is active in the American Dietetic Association, and offers her nutritional services through their national network. Liz also speaks to a variety of schools and health care professionals in both New Jersey and Pennsylvania regarding eating disorders awareness. The most significant factor in Liz's success with her eating disordered patients is that she herself had Anorexia Nervosa. During her adolescence, she sought professional treatment that only had a marginally positive effect. It was not until she was in her early twenties, when she devoted herself to the study of nutrition, that she truly recovered. She strongly believes that part of her continued recovery process is setting a healthy example for her patients. Liz enjoys many indoor and outdoor exercises, especially when they involve her two children; and believe it or not, she also loves to cook!
