OUR TEAM

Roller Weight Loss & Advanced Surgery employs a multidisciplinary, team approach to provide specialized bariatric medical care. Our program coordinator assists each patient with all phases of the program. Dr. Kristin Roller leads the medical side of the team and evaluates each patient thoroughly from a medical perspective prior to weight loss surgery (bariatric surgery). Our dedicated bariatric dietitian provides both pre and post-op nutritional counseling to help patients maximize their weight loss potential. Our clinical psychologist performs an extensive pre-operative psychological evaluation and counsels patients on behavioral and life-style issues related to weight loss surgery. Post-operatively, the psychologist continues to follow patients, providing guidance and support.

Our program seeks to ensure that patients are making informed decisions, are qualified candidates for surgery and are committed to making the lifestyle changes necessary for long-term weight loss success.
