★★★★★Migdalia MorilloOur son has been going to HAT camps for three years and he loves them. The coaches are great, make it fun and deliver great quality programs. Our son plays competitively and always wants to go back for more training there. Thank you HAT!
★★★★★Ben WHigh Altitude Tennis is the best place in Colorado for competitive juniors to develop their tennis game. It is not for everyone, so if your child is only looking to play for fun put them in a recreational program. HAT is dedicated to developing high level junior players looking to take tennis to college and beyond. With the great coaching not only in tennis, but also in conditioning, mental toughness and nutrition this is the place to send your kid if they are serious about tennis!
★★★★★Nancy COur son has attended High Altitude Tennis for several years and we have been very happy with the whole experience of the academy. Our son has been able to receive comprehensive tennis instruction in a structured, yet fun, and safe environment. The fitness and tennis instructors have provided him with all the help and inspiration that he has needed to achieve his personal goals. This environment is by far the best that we have experienced in the many years that he has been learning the game of tennis.
★★★★★Karen StrodeMy daughter has been attending HAT for a few months and absolutely loves it! The coaches are great and motivate the kids to work hard and do their best. They have taught her how to overcome challenges that she will use on and off of the court. Not only do they support the children but the parents receive support and guidance as well. We are very thankful that we found this program.
★★★★★M ChowdhuryHigh Altitude Tennis is an outstanding competitive junior program. My daughters absolutely love this program and as a parent I am extremely happy with their improvement. The coaches are all very knowledgeable and willing to help whenever needed. I would highly recommend this program for the junior player who is ready to work hard and ready to rise to the next level. Remember this program is not for everyone. This program is geared for the junior who is ready to work hard with a positive attitude. If you are selected for this program, you will be marching towards success.
