HealthLINC was very pleased to welcome Frank Regester to the Board of Directors in February of 2016.

Since the mid-1990’s, Frank Regester has been a pillar of the Bloomington Health IT Community.  In 1997, after building a Novell and Microsoft Network training and development business with his former employer, he was recruited by Unity Physician Group to be their Director of Information Services. There he oversaw the implementation of several complex health information systems.  He stayed with Unity after their merger with Franciscan Alliance, until joining The Peoples State Bank as their VP, IT Director in 2014.  We are happy to have him back in some small part.

Frank was one of the founders of HealthLINC, being on the initial committee that created the Bloomington E-Health Collaborative.  His deep knowledge of computer systems and networking brought to our medical community invaluable expertise.  With his involvement, we were successful in choosing and building a solution to securely share medical results.

By nature, Frank is very collaborative.  Due to his leadership, several large practices enjoyed successful implementations of very complicated EMRs, including a new enterprise PACS management and archiving solution for Southern Indiana Radiological Associates.

Frank is a native son of Bloomington, as his ancestors settled here in the late 1800’s, moving from Jay County Indiana.  He and his wife Joyce have two children and one grandchild.  They are involved with charitable organizations such as Homeward Bound Indiana and Habitat for Humanity among others.
