SPRINGFIELD — The Vann Group, a strategic consulting and transactional advisory services firm, announced that its client, Serv-U Locksmiths of Western Massachusetts, has been acquired by Island Master Locksmiths (IML).

The company, originally founded in 1954, has been a trusted physical-security provider across Western Mass. and Northern Conn. Steven Horowitz, former owner of Serv-U, will stay on in a consulting role during the transition.

“I’ve poured my heart into this business for decades and am proud of everything our team has accomplished,” he said. “I have complete confidence that IML will honor our history while taking the business to new heights. I’m excited to support this next chapter.”

IML Security was acquired by Northwoods Partners, a family office investment group, in April 2023. Since then, the company has experienced rapid growth and continues to expand its footprint from Maine to Virginia.

“This acquisition represents an exciting step in our growth strategy,” said Sean O’Hayre, president of IML Security. “Serv-U has built a remarkable legacy based on trust, technical excellence, and outstanding service. We’re thrilled to carry that legacy forward while introducing additional resources and innovation to the region.”
