Our Team

Multidisciplinary Team Approach with Individualized Support and Care

At Bayhealth, we recognize that optimal outcomes from weight loss surgery rely on support not just during surgery, but before and after a surgical procedure. Patients are more likely to be successful with long term weight loss efforts when they receive one-on-one attention. This type of unparalleled support follows patients from the very start of their journey through surgery and beyond.
