Early Life and Background
Simona Waltert was born on 13 December 2000 in Chur, a city in the Swiss canton of Graubünden. Growing up in Switzerland provided her with access to a strong tennis culture and a network of European junior competitions. Her home country has produced a long line of successful players, and Waltert developed within that supportive environment from a young age.
She began competing on the ITF Junior Circuit as a teenager and quickly showed promise against some of the top young players in the world. Her junior results laid the foundation for her decision to turn professional, and by her late teens she was ready to step into the demanding world of tour-level tennis.
Path to Tennis
Waltert emerged as a notable junior at the 2017 Wimbledon Championships, where she reached the girls’ singles semifinal before losing to eventual runner-up Ann Li. That same year she was building a strong reputation on the ITF Junior Circuit, and on 22 January 2018 she achieved a career-high combined junior ranking of No. 9.
After her junior success, Waltert transitioned to the professional ranks in 2019, the same year she began working with coach Stéphane Bohli. She made her WTA Tour main-draw debut at the 2019 Ladies Open Lausanne after receiving wildcards for both the singles and doubles draws, signalling her rapid rise within Swiss tennis.

The opportunity allowed her to test her game against more established opponents while continuing to develop her skills on the ITF Circuit. These formative seasons gave her the match experience needed to compete at higher levels in the years that followed.
WTA Tour Breakthrough (2021–2023)
Waltert earned her first WTA Tour doubles title at the 2021 Ladies Open Lausanne, partnering fellow Swiss player Susan Bandecchi. The win was a milestone moment and confirmed her potential as a doubles competitor at the tour level.
The 2022 Ladies Open Lausanne proved to be a turning point in her singles career. As a wildcard, she stunned world No. 7 and top seed Danielle Collins, saving three match points in the deciding tiebreak to secure her first top-10 victory. She followed that with a win over Cristina Bucsa to reach her first WTA Tour quarterfinal, where her run ended against Olga Danilović. Later that season, Waltert added another doubles title at the 2022 Bronx Open alongside partner Anna Blinkova.
Waltert made her Grand Slam debut at the 2023 French Open, defeating Elizabeth Mandlik in the first round before falling to Elisabetta Cocciaretto in the second round.
