Prime Source Services and Caretech Group have formed an alliance, the companies announced.

The purchasing companies work with more than 300 senior care facilities in eight states.

Caretech Group works on providing data-driven software tools in nursing homes and to improve the provider’s financial health, while Prime Source is a procurement management group. A sister company of Prime Source Services is Prime Source GPO.

Michael Greenfield, the Prime Source CEO, will join Caretech as its director of business development. He will also retain control of Prime Source GPO as it is spun off independently.

“In essence, everybody stands to gain from this powerful strategic alliance,” Greenfield said.
