Tennis connects Sergej Prosen, Tomaž Berendijaš and Aleš Filipčič. In 2014 they incorporated Biometrika LLC in an effort to introduce data analytics approaches into tennis training and teen player development.
Sergej is a tennis parent, used to chauffeuring his daughter from practice to practice, tournament to tournament. He experienced first hand the frustration of not being certain if all the work, investment and sacrifice is adding up to a proper start of a professional career or if it’s just precious childhood time that could have been better spent.
Aleš is an associate professor of kinesiology (that’s a fancy name for sports) at the University of Ljubljana and specializes in tennis. As an ITF touring coach he worked with the likes of ATP No. 3 Grigor Dimitrov (15 years old at the time). Ales designed a national Coaches Education System framework and conducted more than 100 coaching courses for Tennis Coach level A, B, C and D license. He is also a published author of several tennis books, DVD’s and scientific and professional papers.
Tomaž holds a Master of Science degree in Sports, Health and Physical Education and Fitness. He works as a Tennis coach at Slovenia’s No. 1 tennis club – ZTK Maribor. And he was also a teen player working his way up the rankings. A true tennis devotee, Tomaz spends most of his time in the role of coach, also lecturing and educating next generation coaches.
