Sandra Zaniewska

Former professional tennis player. Current coach of WTA world No. 11 Marta Kostyuk. Former High-Level Director at Mouratoglou Tennis Academy.

I write, teach, and speak about the deeper side of tennis development — identity, pressure, trust, decision-making, and the long arc of a player’s growth.

My work

My work sits at the intersection of performance, development, and the human side of tennis.

Besides working as a coach on WTA tour, I create courses, books, and essays for parents, coaches, and players who want to understand the game beyond results and rankings — the decisions, relationships, environments, and emotional patterns that shape a player over time.

Courses

Parent education and long-term development frameworks.

Books

Practical resources for coaches and families navigating the tennis journey.

Writing

Essays on coaching, identity, pressure, and the unseen parts of performance.
