Brett Fellows, CFP®

Founder & President

Welcome! I’ve lived in Charleston since 2005, the same year I launched Oak Capital Advisors.

Prior to moving here, I had ownership in a Boston-based golf operating company for nine years. My experience in the golf industry taught me a lot about the relationship between business and money.

As a CFP® professional I help local entrepreneurs and business owners reduce risk, minimize taxes, and invest smarter so they can confidently retire on their terms.

When I’m not perfecting exit and retirement plans for my clients, you can find me on the water with my wife (Colleen), at Clemson University with my daughters (Grace & Margaret), or walking my golden retriever (Chase). If all else fails, you’ll find me at RiverTowne CountryClub attempting to master my golf game.
