Your Edge in Healthcare

Howell Health Hub

Livingston County, MI

Building Overview


Since the 1950’s, some incredible stories and historical events have been written at 645 W. Grand River, Howell, Michigan, the former corporate headquarters for Hanover Insurance. Now, where the original building stood, a new story is being written. As a new era of transformation unfolds, an exciting destination is taking shape that will be a hub for medical and healthcare leaders servicing the greater Livingston County area. 


The Howell Health Hub (“H3”) has recently embarked on a transformative multi-million-dollar investment, making it a premier Medical Office use building in Livingston County. Upon completion in late 2023, H3 will feature a completely new exterior façade, new multi-story atrium with patient drop-off/pick-up, new monument signage opportunities, and complete modernization of the interior mechanical systems (HVAC) conducive to Medical and Surgical Use. Once complete, The H3 will possess Class A curb appeal to match what will be unparalleled interior tenant improvements. 

The reimagined atrium will span two stories on the south side of the building, with immediate elevator access, covered patient drop-off/pick-up, ADA access, all glass natural light throughout, and custom light fixtures and artwork. There is an abundance of on-site parking immediately surrounding the building, for easy access for patients and visitors. Located on the western edge of Downtown Howell, The H3 marks the centerpiece of the greater Livingston County community.
