New Mountain Capital, a growth-oriented investment firm, has made a majority investment in Citrin Cooperman, a full-service advisory, tax, and assurance firm.

Since receiving its investment from New Mountain, Citrin has expanded by partnering and integrating accounting and consulting firms that synergistically fit with the firm’s culture and business model of advising middle-market firms and HNWs. The partnership will allow the firm to continue to seek out and acquire technology and advisory services. The investment represents New Mountain Capital’s commitment to financial services and risk and compliance sectors.

“We have known the leadership of Citrin Cooperman for ten years, and we are excited to provide strategic and financial resources to the partners of Citrin Cooperman as they accelerate their organic and inorganic expansion,” said Andre Moura, managing director at New Mountain Capital. “Citrin Cooperman is an outstanding firm, and we are pleased with all the progress that has already been made in the first six months since our investment.”
