Teresa was born in Barcelona, Spain, and grew up playing tennis at the historic Real Club de Tenis Barcelona 1899—home of the Masters 500 tournament and a training ground for many of Spain’s top players.

A nationally ranked junior, Teresa represented Spain in numerous European competitions and later coached several of the country’s national teams. Before moving to the United States in 1984, she became the first female tennis instructor at the Real Club de Tenis Barcelona, where she taught for ten years. During that time, future stars such as Arantxa Sánchez Vicario (former World No. 1) and Carlos Costa (now Rafael Nadal’s agent) trained at the club’s academy. As a coach, Teresa emphasizes strong technique—proper grips, clean swings—and disciplined footwork, using the Spanish developmental method she grew up with and continues to teach today.

Since relocating to Fresno, Teresa has taught across several premier facilities, including Fresno Racquet Time (1984–1986), Fig Garden Swim and Racquet Club (1986–1990), private instruction (1990–1995), Copper River Country Club (1995–2000), and Sierra Sport & Racquet Club as an independent contractor from 2000 to the present. With over 40 years of coaching experience, she is certified by the Real Federación Española de Tenis in Spain and has been USPTA-certified in the United States since 1985.

Teresa holds a degree in Liberal Studies from the Universidad Autónoma de Barcelona.
