The Executive Women’s Day Luncheon at the Charles Schwab Challenge announced tennis hall of famer Martina Navratilova as the event’s keynote speaker.

The luncheon is May 21 during the 78th Charles Schwab Challenge PGA TOUR tournament at Colonial Country Club and has become a powerful event for celebrating, empowering and inspiring women.

“I am honored to be invited to join Executive Women’s Day at the Charles Schwab Challenge as the keynote speaker,” Navratilova said in a release. “Life is about challenges and how we face up to them and the attitude we take into everyday life, so hopefully, we’ll be able to motivate people to do more with their life.”

Navratilova entered the International Tennis Hall of Fame in 2000 after winning an unprecedented 59 grand slam titles. A Czech American athlete, her accomplishments include nine singles championships at Wimbledon, three at the Australian Open, two at the French Open and four at the U.S. Open.

A rivalry with fellow tennis great Chris Evert lasted 15 years and 80 matches. Navratilova walked away with a 43-37 advantage.

Navratilova earned the WTA’s “Tour Player of the Year” seven times, was named The Associated Press’ “Female Athlete of the Year” twice and declared one of the “Top Forty Athletes of All-Time” by Sports Illustrated.

After being inducted into the hall of fame, Navratilova participated in the 2004 Olympic Games and WTA events. Her final tour appearance came in 2006, just shy of 50, in the U.S. Open. She became the oldest player to win a Grand Slam title in the mixed doubles championship with Bob Bryan.

Following an illustrious career, Navratilova has worked on the Tennis Channel, providing coverage of Grand Slams, served as the ambassador for the WTA, and is a commentator for the BBC at Wimbledon. She also wrote a book, “Shape Your Self,” a guide to personal fitness and healthy living.

The EWD luncheon also serves the community through charitable giving with the “Help A Sister Up” fundraising campaign.

“Help a Sister Up” is the result of a partnership between the EWD and Fort Worth Colonial Charities Inc. Last year, the partnership raised $75,000 to support the Boys & Girls Clubs of Greater Tarrant County and the Women’s Center of Tarrant County. A three-year commitment from EWD and Fort Worth Colonial Charities will provide more than $500,000 in charitable impact to the two non-profit organizations.

“After seeing how the donations impacted these charities last year, EWD made it a priority to continue the financial support,” Julie Butner, EWD chair, said. “It is an excellent example of empowering women to use their wealth and power to uplift other women and girls in our local community.”

Luncheon tickets are available on the Charles Schwab Challenge website. Different sponsorship levels are available, including Gold, which features a table for eight, valet parking and other added value premiums.
