Our Team and Their Roles

  • Health Psychologist: Health psychology is a specialty area that focuses on how biological, social and psychological factors influence health and illness. Our health psychologist has expertise in the field of weight management, and focuses on behavior change interventions both before and after bariatric surgery. They ensure that patients are knowledgeable about and capable of making the lifestyle changes necessary to achieve and maintain their weight loss through bariatric surgery. They act as a resource for patients by helping them make the range of changes that foster long-term weight loss success and overall life satisfaction.
  • Registered Dietitian: A registered dietitian (RD) is the most credible source of nutrition information - a food and nutrition expert. A dietitian evaluates a person’s nutritional intake and relationship with food, then assists patients in establishing a healthy approach to eating and a lifestyle that supports weight loss as well as weight loss maintenance. The dietitian monitors nutrition, supplements and the potential for eating problems.
  • Nurse Practitioner/Physician Assistant: The nurse practitioner (NP) and physician assistant (PA) are health care professionals who have completed advanced education and training in the diagnosis and management of common medical conditions. They provide some of the same care provided by physicians and maintain close working relationships with physicians. The NP and PA help patients bridge the gap between the clinic and hospital, address their concerns before and after surgery and help to find a balance in their health and wellness.
  • Surgeon: The surgeon oversees patient care and performs the surgery. Your surgeon will discuss the risks and benefits of each procedure and answers any questions. UW Health bariatric surgeons are specially trained in minimally invasive surgery and are certified by the American Board of Surgery.
  • Program/Medical Assistant: The program/medical assistants (MAs) help the clinic and program run smoothly. They answer questions, facilitate communication, schedule appointments and help with additional tests and procedures. The MAs also help patients work with insurance plans and assist in coordinating the surgery date and follow-up care.
  • Program/Clinic Manager: The program/clinic manager manages the clinic operations and resources, oversees program development and workflow and is responsible for clinic staff and overall patient experience.
