Annika Sorenstam is one of the greatest women’s golfers of all time. A 10-time major championship winner, Sorenstam is known for an incredible, efficient back and through swing and thriving under pressure. In 2003, at the peak of her career, she teed it up with the men on the PGA Tour , the first woman to do so in 58 years, and not without controversy and pushback.

By the time she retired in 2008, she’d won the US Open three times and is still the only woman to break 60 in a competitive round—something not even Tiger Woods has accomplished. Now, with her Annika Foundation, the 54-year-old Sorenstam looks to foster the next generation of women and girl golfers through a variety of charitable endeavors, including mentorship, financial support and even sponsoring tournaments across the world that highlight the women’s game. It has her on the road constantly, though home is in Orlando, where she lives with her children, Ava and Will, and husband, Mike McGee, who’s managing director of the foundation.

In September, Sorenstam teamed up with luxury eyewear maker Revo to launch a new line of unisex sunglasses bearing her name.
