Jeanie Wyatt, founder and chairwoman of South Texas Money Management, died of cancer on Tuesday. She was 65.
"Jeanie was an inspiration to all of us, and indeed, to all who met her," STMM co-CEO Teri Grubb said in a company news release. "Her illness took her from us too soon."
Ms. Wyatt named Ms. Grubb and Christina Markell-Balleza co-CEOs earlier this year.
Ms. Grubb added: "Typical of her devotion to our clients, she took it as an opportunity to plan a smooth transition. She built a strong organization and emphasized to us that the best way to honor her legacy is to continue that devotion. We will be working every day to do just that."
Ms. Wyatt founded STMM in December 2000 and served as CEO and chief investment officer. She grew the business from one office and $10 million to six offices in Texas and $3.7 billion in assets under management as of Jan. 31.
In multiple years, Barron's named Ms. Wyatt to its Top 1,200 U.S. Financial Advisors by State list, the Top 100 Women Financial Advisors list and the Top 100 Independent Wealth Advisors list.
Ms. Wyatt served on the board for the Employees Retirement System of Texas in 2016 and served on Texas' State Pension Review Board.
She is survived by her husband William I. Wyatt Jr., her three sons and their families: Angela and Trey Rabke, Joan and Richey Wyatt, and Susan Ludwigson and John Wyatt, plus eight grandchildren.
Memorial service plans will be announced on the firm's website.
