Our Story

ChronWell was formed in 2017 by the team that built the largest Gastroenterology information technology platform in the US with the vision to change Workers Compensation by spending the right amount of time on the simple things that can help injured workers and patients take giant leaps forward.

The company eventually developed a unique and dynamic platform that tracked the progress of an injury from the initial point in which a worker was injured through return to work.  This lead to a revolutionary Early Intervention program that has helped reduce costs, track injuries and assist in appropriate reporting. As the platform evolved, the team realized our solutions could be used on a larger scale to help

healthcare providers manage expensive chronic conditions beyond the medical practice, capitalizing on new care management opportunities approved by Medicare.  Traditional practices did not have the team or information systems to manage patients remotely and they relied on our experience partnering with large medical practices to implement innovative programs to reach beyond the practice.  The new COVID-19 Pandemic accelerated our development timeline and forced impaired practices to activate new revenue lines to manage patients remotely, leading to a different way to think about patient care.  This story is still being written today

Our Vision

To improve healthcare by extending the reach of all providers beyond their practice, to improve outcomes and reduce cost through innovation and digital transformation.
