Kevin Oliver

President & Founder

Kevin started his career in tax while attending the University of North Texas. One evening in the Spring of 2003, he was at Chili’s having dinner with his older brother Mike, a well-respected CPA who owned a practice in Rockwall, TX. Over chips & salsa, Mike offered Kevin a job at his tax practice as a bookkeeper/tax preparer. From there, the rest was history.

After having spent many years in tax, Kevin discovered a passion for entrepreneurs that led him to start a new tax practice. After working with one of the largest BBQ restaurant chains in North Texas as their fractional CFO, an idea sparked that transformed his business from a traditional tax/bookkeeping firm into a tax advisory practice. Being more involved with clients on a CFO-like platform gives him a great deal of joy, which is how Oliver Tax Group was born.

Kevin and his wife Angela live in Rockwall, TX. They have three children, one boy and two girls, who attend Heritage Christian Academy. Music is at the heart of their home, with Kevin actively playing trumpet in the Dallas music scene and his wife who is an all-star piano & clarinet player. He shares his wife’s passion for last minute vacations, Universal Studios, & Harry Potter.
