Group Class

A weekly, evening class with a group of 10-12 individuals all beginning their weight loss journey. Classes are run by a trained psychologist and supported by the dietitian and physician. This is a 6-month intensive program.

Pre-Surgical Program

For individuals who need to lose weight prior to an upcoming surgery in order to lower their surgical risk and improve outcomes. The program will typically last  3-6 months and may incorporate physical therapists to help improve physical strength prior to surgery.

One on One Meetings

A one on one program can be very effective for losing weight to improve appearance and physical performance. These patients may need to lose just 10-20lbs. Programs are tailored to each patient and can fit any weight loss needs.

Gastric Balloon

An alternative to gastric bypass might be the temporary placement of a stomach balloon to curb appetite. We use only FDA approved procedures including Obalon and Orbera Balloon systems. Longterm, everyone will need training in diet, lifestyle, and forming daily habits.
