BTT Tennis Academy, an international tennis academy located in Valldoreix, Barcelona, Spain, has for several years had a strong partnership with USTA Player Development. hose players who train at BTT Tennis Academy are accompanied by USTA Player Development National Coaches who collaborate on a day-to-day basis with the BTT Tennis Academy staff, thus ensuring continuity in the players' training goals with the benefit of BTT Coaching input. The BTT methodology, created years ago by its founders-directors Francis Roig, Jordi Vilaró and Álvaro Margets, is applied in the daily training on the court combined with a specific fitness program in morning and afternoon sessions.
