Sem Verbeek was born on 12 April 1994 and comes from Amsterdam. As a schoolboy in the Netherlands he emailed nearly every American university with a pre-medical programme, and only the University of the Pacific in Stockton, California, replied. He joined the team as a walk-on in 2012, won a scholarship, and in 2016 was West Coast Conference Player of the Year.
He built a doubles career on the Challenger circuit and reached his first ATP final at Los Cabos in 2021. In 2024 he made his debut at the majors as an alternate, won his first Wimbledon match with Romain Arneodo, and took his first ATP title on grass at Newport with Andre Goransson.
In 2025 he and Goransson reached the Australian Open semi-finals on their debut there, and in July he won the Wimbledon mixed doubles with Katerina Siniakova in their first tournament together, beating the top seeds in the first round. He reached a career-high doubles ranking of No. 29 that May.

The person behind the player.
Stockton, California, 2012
As a high school player he emailed nearly every US university offering pre-med to ask whether they would take him on the tennis team. Pacific was the only one that wrote back, and he joined as a walk-on. He left as the 2016 West Coast Conference Player of the Year, second in the university's career wins list with 125.

Ranked 74th, Verbeek missed the main draw of the 2024 men's doubles and asked on social media for cheap accommodation while he waited as an alternate, because the tournament pays lodging only for the first two pairs on the list. He got in with Romain Arneodo and won his first Wimbledon match.
