About Us

CoreLife History

In 2012 CoreLife created its healthcare model based upon a personal experience, which uncovered a fragmented, uncoordinated, and one-dimensional array of treatment options for obese and chronically ill patients. This led to the development of a community-based, multifaceted model that combines and coordinates the core disciplines necessary to optimally treat obesity, chronic disease states, and their underlying problems and challenges. The synergy of these disciplines are delivered with a focus on health improvement and sustainability.

Today, CoreLife services more than 850,000 annual patient visits and is the trusted partners for PCPs, surgeons, and specialists who identify patients looking to better manage their disease states with the goal of improving overall health, optimizing a surgical outcome, or preventing/impeding/reversing a diagnosis.
