New To CustomisingI

Chris Sanchez

“I started off knowing most of the basics of customising however the course was great as it has really helped me develop as a customiser. The way Nikki explains the terminology and puts it into examples is excellent.”

"Welcome to the UNSTRUNG COURSE. I'm excited to share with you my stringing knowledge and experience that I've gained over the past 15 years.

I started playing tennis professionally which was what prompted me to learn to string at the age of 15. Since then I've gone on to both play with some of the best players in the world, like Djokovic, Federer and Del Potro but also string for them as well. I currently string for Novak when ever he's at his training base.

In 2014 I started the company, UNSTRUNG CUSTOMS. Since then we have grown to become one of the biggest and most well known racket customising companies in the world. We string, customise and specialise in racket painting.

This course is my way of giving back and sharing all the information I've been fortunate enough to pick up a long my journey."
