Who we serve

Advisory shaped to your profession.

Individuals & Families

Returns and planning built around your life — investments, real estate, retirement, trusts, and estates — and everything in between.

Healthcare Professionals

Physicians, dentists, veterinarians, and group practices face unique entity, compensation, and retirement questions — and from associateship to ownership, we guide them through practice acquisition, equipment planning, and growth. We answer those questions year-round.

Professional Service Firms

Attorneys, consultants, architects, and engineers trust us with books, taxes, and the numbers behind the business.

The firm

Counsel built on trust, kept for decades.

A. G. Mangum & Co. is a Chapel Hill tax advisory firm, comprised of experienced CPAs and EAs, serving individuals, business owners, executives, and health care professionals throughout Chapel Hill, Durham, and the surrounding communities. We believe good tax work is quiet, careful, and constant — not a once-a-year scramble.

Our clients stay because we know their practices as well as their returns: the associate becoming a partner, the dentist buying a first practice, the firm ready for its next stage of growth.

Chapel Hill: Since 1966
Year-round: Planning, not scrambling
Practices: Medical, dental & beyond

Our team

The people behind the practice.

Kirk Mangum

Principal

Kirk joined the firm his father founded in 2003 and has led it since 2016. He holds a B.S.B.A. in Finance, Insurance and Real Estate and an M.S. in Accounting with a tax concentration, both from Appalachian State University. A licensed North Carolina real estate broker, he spent more than eight years practicing commercial real estate before joining the firm — experience that gives him a practical, big-picture view of how tax decisions shape property, investments, and business growth. Deeply involved in the Durham community through his church and several nonprofit boards, he is also an avid outdoorsman who has thru-hiked the 2,100-mile Appalachian Trail and served 28 years with the National Ski Patrol.

Grant Mangum

Founder

Grant founded the firm in 1966 and, for more than 55 years, successfully consulted hundreds of healthcare professionals across North Carolina, South Carolina, and Virginia. The trusted relationships he built — many spanning decades — remain the foundation of the practice today.
