Although he has worked with clients trying to lose weight for several years, this is his first experience as a group leader. He has been hired by a local physicians' practice to run this group at the hospital's wellness center. All group participants have been referred by their providers and have been diagnosed with obesity and related health disorders such as hypertension or diabetes.
