Berkshire Partners-backed 3Phase Elevator, an independent elevator and escalator services provider, completed the acquisition of Specialized Elevator Services Holdings, an elevator service company, from CIVC Partners, a private equity firm. Financial terms were not disclosed. “We set out three years ago to become the premier elevator service provider for customers, and to be the employer of choice for union mechanics in the major California markets. Merging with 3Phase provides us with a transformational opportunity to take our commitment to customers and employees at a national level as the only independent IUEC service provider with true national scale," Donovan McKeever, Specialized Elevator Services President.
