Why Work With Me


I’ve been playing tennis since I was 5 years old and I still love competing and getting better at it. What I’m specially passionate about is seeing another motivated player, no matter what age, willing to work hard and get better.


My experience of playing tennis over 25 years gave me the opportunity to learn a lot about the game but also about coaching. I’ve worked with many different coaches which taught me over years that teaching often requires ability to explain the same thing in many different ways.


I’m always ready to come up with exercises that would best fit personal needs for every player, as well as finding multiple ways of learning new elements in order to achieve improvement in short period of time.


Working with players ranging from U10 to 65+, as well as working with active players and amateurs, requires adapting your methods and exercises in order to achieve best results.


Ability to stay positive it’s very important in tennis. “Bad days” in tennis can be very frustrating but as long as you are trying and doing you best on those days, you are moving in the right direction. No matter how many mistakes you make.

Attentive to details

Contact point, grip, swing, footwork, balance and other elements all need to get in line for a good stoke. Working on those elements is very meticulous process that requires constant attention and corrections.

``Mistakes don't mean failure. On the contrary, mistakes are a key feature in improvement``






Stuff I’m Really Good At

Forehand, backhand, volleys, serve, footwork and other elements require constant improving and calibration.

Accepting and getting confident with new stuff is as important as learning it. Let me help you get more consistent and better in elements you would like to work on. Countless repetitions do pay off.


- Let's test your skills -


Whenever you are ready, I'm available to test your skills and push your limits in a tennis match. Aftermatch discussion is great way to learn something new and identify strengths and weaknesses.

Get to know your strengths and weaknesses and create a game plan around them. Let the numbers be your friend in a match, not an enemy.
