Professional Coaching Qualification

  • European 14/U Player development coach
  • Global Professional Tennis coaches Association – Level B

Having been in a fairly unique position of sponsoring, coaching and travelling with a player for a few years l developed my coaching style based on many different aspects of the game.

Visiting 55 countries and training at many different academies including Paraguay, Argentina, Spain, Sweden, Australia, the Uk, France, Slovakia, Thailand, and Japan to mention a few – l was able to study their different programmes. This, combined with watching hundreds of live matches and training with or watching world class players training up close, helped me to formulate what l believe is an effective way to develop top players from the ground up. l attended various courses and symposiums; the most prominent being the European 14 and under player development conference which is attended by the Head coaches of National federations of the 49 member countries. The leading federations all outlined their development pathways for the next 5 years and I was fortunate enough to be privy to this kind of information.

I have developed players using strict but patient systems and these have proven results.

Players l have worked with include:

  • Mona Barthel 80 – 60 WTA
  • Gail Brodsky 340 – 217 WTA
  • Lisa Marshall 0 – 365 Juniors and 750 WTA

Most recently, l developed players from the age of 6. Between the age of 9-11, these players had gone on to become leading players in Australia in their age groups.

I look forward to working with OTR and hope I will have the opportunity to again develop future top players in Hong Kong.
