About Us

Big Time Tennis began in 2008 in a garage, with David and Paul Yamane stringing rackets for themselves and a couple of friends. Our business has grown exponentially since then.

We provide professional service to players of all levels, from neighborhood kids and USTA League players to collegiate All-Americans and touring professionals. The same care and attention we give to touring professionals we give to every customer we work for.

This hard work was recognized when David was named the Tennis Industry Magazine Stringer of the Year for 2014.
