Mathias Frodin: The Swedish Father and Constant Supporter
Thea’s father is Mathias Frodin, a native of Köping, Sweden. He moved to the United States shortly after finishing high school and settled in the Los Angeles area, where the family now lives in Woodland Hills. Mathias has been deeply involved in Thea’s tennis journey from the beginning. In earlier interviews, Thea has called him her biggest supporter and motivator, noting that he travels with her to nearly every tournament and helps her stay focused on improvement.
His Swedish roots also explain Thea’s dual citizenship. She holds both American and Swedish passports, a detail that occasionally sparks interest among Scandinavian tennis fans hoping she might one day represent Sweden. Mathias’s steady presence has given Thea the kind of practical, day-to-day backing that young players need when balancing school, travel, and high-level competition.
The Mother’s Multicultural Influence
Thea’s mother was born in France and grew up in Gabon. One Italian tennis report has referred to her as Doris. This French-Gabonese background brings a second strong cultural thread into the household. The blend of Swedish, French, and Central African influences has given Thea a broad perspective from an early age, something she has carried onto the international junior circuit with ease.
The family environment appears warm and grounded. Thea has mentioned half-siblings who are still very young, and she sometimes helps look after them when she is home. That everyday family life sits alongside the more intense demands of professional tennis training.
How Family Support Shaped Her Early Path
Thea started playing tennis at age six in Southern California. Her parents encouraged the sport without forcing it, and the results followed quickly. By her early teens she was already ranked among the top players in her age group in the United States. When the opportunity arose to serve as the tennis body double for the young Serena Williams character in the 2021 film King Richard, her parents supported the unusual experience. Thea later joked that she had to unlearn Serena’s strokes afterward because she had copied them so carefully on set.
Key elements of parental involvement include:
- Consistent travel and on-site support at junior events
- Help balancing online schooling with a heavy tournament schedule
- Encouragement to develop her own style rather than simply imitating idols
- Creating a stable home base in Woodland Hills despite frequent travel

That combination of support, travel logistics, and cultural breadth has helped a California teenager step onto the biggest stages with confidence.
As she continues to climb the rankings, Thea Frodin’s family background remains an important part of understanding the person behind the rising tennis star.
