Andy Heinz


Andy began his career with OverRidge, LLC over 20 years ago as an intern while he was studying at the University of Texas at Arlington. Today, he owns the firm.

Andy’s passion for investing started when he was 18 years old while seeking an investment advisor to help him with a small high school graduation gift he’d received from his grandparents. Andy’s passion for helping people came after his grandfather introduced him to his personal investment advisor, Lee Johnson, in 1995. Lee obviously hired Andy, and let’s just say the rest is history.

Andy was awarded a bachelor of Business Administration with an emphasis in Finance from UTA in 1997. He holds the FINRA Series 7 and 63 licenses as well as a general lines license with the Texas Department of Insurance. He lives in Mansfield with his wife, Michelle, and their two sons, Hayden and Jacob.

Besides his work, Andy has a long list of loves … enjoying God, family and friends, being a husband, being a dad, working in the yard, listening to the Rangers games on the radio (the way his grandmother did), Sunday afternoon naps, reading, traveling, working Sudoku Puzzles, doing early morning workouts, turning on the charcoal grill, trying new restaurants, and eating thick cut bacon.
