Born in San Diego in 1990, Mathewson picked up a racquet at 13 through adaptive tennis at the Barnes Tennis Center in Point Loma. She attended the University of Arizona, studied audiology in London, earned a doctorate in audiology in May 2023, and moved to Orlando to train full time at the USTA national campus. She reached No. 7 in the world in singles and No. 4 in doubles, the 2017 US Open doubles final and the 2019 US Open singles semi-finals, and played three Paralympics, from Rio in 2016 to Paris in 2024. At the Parapan American Games she won doubles gold in 2019 and singles and doubles gold in 2023, when she was the US flag-bearer. She won 16 singles and 32 doubles titles and retired in November 2024, after the Masters events.

"I didn't think I would be an athlete. I thought that whole part of my life was done," she said of her childhood. Adaptive tennis at the Barnes Tennis Center in Point Loma changed that, and she called the sport "a huge part of me finding my independence".
Her first Wimbledon singles match was a 6-1, 6-1 defeat by the world No. 1, Diede de Groot. In the doubles final she and Kamiji met de Groot and Aniek van Koot, the top seeds, and won 6-1, 7-5, the Dutch pair making 16 unforced errors to their three.
She called the title "pretty surreal" and took comfort that her name would be painted in gold on the wall at the All England Club. One thing was missing from her fortnight. "I'm really sad I never got to have my strawberries and cream," she said.
At her last US Open she explained why she would stop after Paris: top players spend 20 to 25 weeks a year on the road. "I love competing, I love tennis, it's just the lifestyle I'm ready to hang up." Her idol growing up, she said, had been the American Paralympian Karin Korb, who "was strong and beautiful".
At the Parapan American Games in Chile she was chosen as a US flag-bearer, in part for her work in opening a path for wheelchair tennis and inspiring the next generation. She then won gold in both singles and doubles, four years after doubles gold and singles bronze in Lima.
She announced her retirement on Instagram during the week of the Masters events, her last as a professional, with plans to coach, commentate, mentor players and run tournaments. "Tennis and I aren't breaking up, we're simply forming a new relationship, and I can't wait," she said.
