Val also had a major influence on Mary’s development as a player. He played professionally after college and later became a coach, introducing Mary to tennis while also teaching her older brother.
She grew up in Southbury, Connecticut, alongside her family. Her mother, Kathleen Morrone, also played an important role in her development, eventually putting her career as an interior designer on hold to homeschool Mary and accompany her to tournaments.
What is Mary Stoiana’s current ranking?
Mary Stoiana is ranked No. 122 in the WTA singles rankings as of August 31, 2026. That is also the highest singles ranking of her professional career to date.
Her climb has been one of the most notable parts of her first full season on the professional circuit. She started 2026 at No. 223 and steadily moved upward, reaching No. 122 by the end of August.
The ranking rise has also coincided with her arrival at the Grand Slam level. She qualified for the 2026 US Open main draw after winning three qualifying matches in New York.
At what age did Mary Stoiana start playing tennis?
Mary Stoiana started playing tennis at around 4 years old. Her father, Val, introduced her to the sport while he was also teaching her older brother, and she quickly developed the fundamentals of the game.
She began competing in USTA junior events at age nine and later moved onto the international junior circuit. From 2018 through 2021, she won three ITF junior singles titles and one doubles title.
Her development accelerated during her teenage years. In 2019, she finished seventh at the USTA Girls’ 18 National Clay Court Championships, a result that helped attract the attention of Texas A&M.
Who is Mary Stoiana’s coach?
Mary Stoiana has been coached by Fran Vittar since October 2025. Before turning professional, she spent her college career under Texas A&M head coach Mark Weaver.
Weaver guided her through one of the most successful periods in Aggies women’s tennis history. Under him, she became the first Texas A&M player to reach No. 1 in the ITA singles rankings and the first Aggie to win the ITA National Player of the Year award.

The amount is particularly notable given that she spent the majority of her early professional development playing college tennis rather than competing full-time on the WTA Tour.
Her earnings have increased significantly during 2026 as she has progressed through larger tournaments and established herself inside the Top 150. Her first Grand Slam main-draw qualification at the US Open represents another important step in that progression.
