They care about tennis and helping your child achieve what they want more than almost any other coach I know. They also know how important having fun on court is and make it a great experience.

Having my children in their programs is something I am proud about, and I know you will be too!

My 7 year started Colossal without being able to hit a ball and after 2 sessions has developed a great understanding of the basics and has been improving significantly after each class.

Danny and his staff provide genuine hands on learning in a fun safe environment where all kids have plenty opportunities to participate in each drill. The class moves very efficiently and kids are always on the move and the staff is always taking the time to provided some extra one on one training when needed.

I HIGHLY recommend Colossal to anyone who wants their child to learn the game. They’ll learn a lot and have a blast at the same time!

I'm a tennis parent of two young boys who love tennis. I am thrilled to recommend Colossal, the remarkable tennis academy where my son trains alongside talented young athletes.

Colossal not only helps young players achieve their tennis dreams but also emphasizes fun, friendship, and valuable life lessons through the sport. Their financial support for local high school tennis teams showcases their commitment to giving back to the community.

With exceptional coaching, a nurturing environment, and a focus on holistic development, Colossal has truly made a positive impact on my son's tennis journey.

I am the parent of a long time Colossal player. My daughter was first introduced to Sion around age 6. She was the spectator of a doubles match he played with her then coach.

When our beloved coach moved to Texas we were encouraged to check out Colossal. We were promised to be in dedicated hands and that promise has for sure stood the test of time!

Sion and Danny are not only dedicated to the game of tennis they are dedicated to ensuring kids grow up having fun on the court. While many of the kids spend endless hours (especially in the summer) hitting balls at Colossal they do so because the competition is as fierce as the level of fun had.

From fixing backhands to hammering down a consistent serve the improvement I have seen in my daughter is spectacular. Her match confidence has been positively impacted by both her technique and the consistent match play with Colossal. Being able to play mix gendered matches daily allows the players to constantly change their strategy and style of play without ever being nervous to show up for a USTA match or a UTR.

Colossal is my daughters home away from home and I am proud to have her be part of an impactful community.
