Coleman Hines began as a woman-owned business in April, 2000. In February, 2012, they were acquired by M&C Energy Group to become the U.S. headquarters for the European-based company. In April, 2012, Schneider Electric acquired M&C Energy Group, the parent company of Coleman Hines. As part of that acquisition, the company joined Summit Energy (a previous acquisition by Schneider Electric) and integrated into the Louisville, KY based team. The previous Coleman Hines office continues to operate out of the Phoenix, Arizona office, as Schneider Electric.
