Meet Our LAP-BAND® Surgery Doctors and Team


LAP-BAND® surgeons serving Colorado, Wyoming, and Nebraska

The LAP-BAND® doctors and compassionate bariatric LAP-BAND team at Bariatric Center of the Rockies work toward the same goal: helping patients lose weight and improve their lives. This dedicated group comes from Poudre Valley Hospital (PVH) and Northern Colorado Surgical Associates (NCSA).

Bariatric Surgeons
Our four LAP-BAND® surgery doctors are board-certified in bariatrics. They are Robert R. Quaid, M.D., F.A.C.S. James M. Dickinson, M.D., F.A.C.S., Stefan M. Pettine, M.D., F.A.C.S. and Michael D. Roller, M.D., F.A.C.S.

Bariatric Program Manager
Lynelle Diede, MSN, RN, is our bariatric program manager. Lynelle has been involved in the care of bariatric patients since 1998. She ensures the program is compliant with all Center of Excellence criteria with a special focus on the maintaining the program's high level of quality and customer service. Additionally, Lynelle oversees the Bariatric Patient Navigator Program, and can assist patients and physicians with any questions they may have.

Certified Bariatric Nurse
Becki Mudgett, R.N., C.B.N., with NCSA, works alongside our LAP-BAND surgery doctors and helps prepare patients for the physical and emotional changes that come with LAP-BAND surgery.

Bariatric Patient Navigator
Michelle Carpenter, R.N., C.B.N., helps guide patients through all the steps on their weight-loss journey, including initial inquiry, pre-surgery weight loss when needed/required and connecting patients to resources after surgery.

PVH Dietary Services
Our dietitians, specially trained in bariatrics nutrition, meet with patients prior to surgery to explain their diet and lifestyle changes. If necessary, additional appointments can be scheduled as well. They will provide each patient individualized education and tools to guide them after surgery.

PVH Surgical Services
PVH has specialized equipment to care for bariatric patients and ensure patient safety throughout their stay. This includes the operating room as well as the inpatient areas throughout the hospital. Treating bariatric patients and their families with dignity and respect is a top priority for all PVH staff. This compassionate team is here to deliver a positive experience for everyone involved.

A patient's mental and emotional well-being is crucial for successful weight loss. Working in concert with our LAP-BAND surgery doctors, Betty Vanek, Ph.D. and Patrick Demarco, Ph.D. evaluate our adult patients to ensure they are psychologically prepared for surgery and emotionally ready to handle the permanent lifestyle changes after surgery. Brian Mesinger, Ph.D. works exclusively with our adolescent patients.

Beverly E. Donnelley, M.D. specializing in obstetrics and gynecology, is available to help with any gynecological and pregnancy prevention issues both before and after surgery.
