What Makes Us Different?


We have a legal and ethical obligation to put your interests first, and we take this responsibility very seriously.

Independent & Fee-Only

As a fee-only financial planner, our compensation comes exclusively from the fees our clients pay us. That means our only motivation is to protect and grow your assets.

CFP® Professional

CFP® professionals meet rigorous education, training and ethical standards, and are committed to serving our clients' best interests.

Brett Fellows, CFP®

Founder & President

Welcome! My family and I have lived in Charleston, South Carolina 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 successful business owners reduce risk, minimize taxes, and invest smarter so they can achieve financial independence.

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 retrievers (Chase & Bruno). If all else fails, you’ll find me at RiverTowne CountryClub attempting to master my golf game.

Our Awesome Clients

Serving the Charleston area and beyond, we do our best work with small business owners who have accumulated investable assets of at least $500,000. In addition, our clients tend to share the following characteristics:

You own a successful business with annual revenue in the seven figures and eventually plan to exit and retire on your terms.

You're looking for a fiduciary, fee-only financial planner to help you determine how much your business is worth, when you can exit, and who you can sell to.

You are seeking peace of mind when it comes to protecting your business, employees, and personal finances from unexpected setbacks and securing your financial future.

Take the guess-work out of your financial future.
