Haefele Flanagan (HFCO) has acquired Durham, North Carolina based Mig Murphy Sistrom, CPA, PC, a firm focused exclusively on nonprofit accounting and advisory services.

The acquisition strengthens Haefele Flanagan’s nonprofit practice and expands our capabilities in outsourced accounting, CFO advisory services, and nonprofit-specific compliance and financial leadership. Mig Murphy Sistrom, CPA, PC will join Haefele Flanagan, bringing deep expertise in mission-driven organizations, grant compliance, nonprofit financial operations, and expanding our geographic footprint in the Southeast.

“This acquisition accelerates our long-term strategy to lead with advisory services by establishing us as a primary player in the nonprofit CAS and CFO advisory space,” said Jim Haefele, CPA, ABV, CVA, CFF, MAFF, leading partner at Haefele Flanagan. “It expands our platform beyond compliance into higher-impact, mission-driven financial management and positions us for sustainable, specialized growth in the nonprofit sector.”

Mig Murphy Sistrom, founder of Mig Murphy Sistrom, CPA, PC, said the decision was driven by shared values, culture, and a long-term commitment to clients and staff. “I am tremendously excited to be a part of the Haefele Flanagan team,” Murphy Sistrom said. “Our clients will benefit from expanded capacity, new efficiencies, and a broader range of services such as strategic planning and support for any related commercial businesses. Our team will benefit from best practices already adopted by HFCO, and from working with a larger team of personable, creative, forward-thinking professionals who share the values that made my own firm special. I very carefully sought to identify a rare firm who would not only provide the economies of scale that accounting firms need in today’s environment, but who offer the kind of culture that our staff and clients appreciate. When I met the HFCO leadership, I was certain I had found that unicorn.”
