Vice Chairman Mo Anderson is the driving force behind Keller Williams Realty’s culture of family. She established her first real estate office, a Century 21 franchise, in Edmond, Okla. in 1975; soon after, it was the third top-producing office out of 7,500 Century 21 locations in North America. In 1986 Mo sold her company to Merrill Lynch Realty, where she served as a district vice president until December 1989.

In 1991, Anderson became the first Keller Williams Realty franchisee outside of the state of Texas when she persuaded Gary to expand his profit share concept for real estate offices. In 1992, she landed the regional director role for Oklahoma and became the co-owner of two Keller Williams Realty market centers in that state.

In 1995, Keller put forth a call to all his regional directors to help him find a new top executive for the company. In January 1995, Keller’s extensive search came to an end when Anderson became president and CEO of Keller Williams Realty, with Keller stepping up to the position of chairman of the board. With the appointment of Mark Willis as president in 2002 and then CEO in 2005, Anderson now serves as the vice chairman for the company. Today, her focus is on cultivating the unique culture of Keller Williams Realty by traveling across the United States and Canada visiting market centers and teaching classes.

A tireless supporter of community causes, Anderson founded KW Cares in 2003 to assist company associates and their families in need and raised millions for Hurricane Katrina relief. Anderson has been named twice as Oklahoma's Women in Business Advocate of the Year by the U.S. Small Business Administration. She is also listed in Who's Who in American Women and was one of ten women profiled in Body and Soul (Hill Publishing). Most recently she was nominated for REALTOR® Magazine’s 2006 Good Neighbor Award.

Anderson serves or has served on the boards of Edmond Memorial Hospital, the Francis Tuttle Vo-Tech Foundation and the Daily Living Center.
