Meet Our Bariatric Team

Multi-disciplinary Team Approach

Attempting to maximize patients chances of having a successful surgical outcome starts with education and knowledge. Although much is gained through personal research, studies show that the pre-operative education and evaluations from a multi-disciplinary team approach of professionals working with the same goal lead to a higher likelihood of successful surgical outcomes.

This team consists of more than the just the surgeon who performs the operation. It includes the many dedicated consultants who evaluate to ensure a safe surgery. Also involved are a team of nurses who routinely take care of bariatric patients post-operatively and bariatric coordinators of the office and of the hospital who act as immediate contact people for support and questions.

The entire philosophy and mutual goal of the multi-disciplinary team is to carefully screen all patients before the surgery to identify any potential problems and correct as appropriate to ensure safety and success during and after the operation.
