Steps for Bariatric Surgery

Get Started on Your Weight Loss Journey!

Make an appointment to meet Dr. Tillquist and learn if you’re a candidate for weight-loss surgery. If you are, find out which surgery is best for you. Note: Dr. Tillquist accepts all forms of insurance.

After your initial consultation, you will begin a 3-6 month diet, exercise, and behavior modification program. The goal is to see if a modification program helps you lose the weight prior to surgery. You must complete the program to move forward with bariatric surgery.

Prior to surgery, every patient is required to complete the FREE pre-op class.
