About Advanced Tennis Foundation
Advanced Tennis Foundation Mission
The concept of Congruent Tennis was born out of two foundational goals, which we refer to as our Dual Objectives:
- Harmonizing Tennis Instruction – We aim to bridge conflicting schools of tennis instruction by developing a more detailed, higher-resolution understanding of how elite tennis is played.
- Serving the Grassroots Community – Our second goal is to offer a diverse, comprehensive, and harmonious array of instructional materials, specifically designed to support the most overlooked segment of the tennis community: grassroots players, parents, and coaches. We recognize that they form the backbone of tennis development, making them critical to the future growth and improvement of the sport.
At Congruent Tennis, we aspire to be an open and accessible source of cutting-edge tennis insights for all who love the game.
But we’re not just here to share what we know; we’re equally committed to learning from the community. Our vision is to foster an environment where every voice is valued. We believe in a bottom-up approach, as opposed to a top-down, authoritative structure. In the Congruent Tennis Community, ideas are discussed and refined based on their quality and merit, rather than deference to authority.
This collaborative spirit is how we plan to uncover fresh insights and discover new truths about the game. By providing everyone with the opportunity to contribute meaningfully, we hope to create a vibrant, innovative tennis ecosystem.
It's a collective effort, and we can’t do it alone. Join us in shaping the future of tennis by becoming a valued member of the Congruent Tennis Community today!

Chuck Tomlin
Coach
Chuck Tomlin, a Naval Aviator and former instructor at the USN Test Pilot Center, added tennis coaching to his resume in 1992, which already included two Black Belts and D1 football. While studying Industrial Engineering at Auburn, he made varsity football as a true freshman. By 1996, he began challenging traditional tennis technique and tactics. Through interactions with top coaches—Bollettieri, Van Der Meer, Rick Macci, Yandell, and Vic Braden—he developed innovative methods to enhance player performance.
By 2002, Tomlin introduced the Serve Code to establish power serving fundamentals, followed by the Congrent Tennis Model (CTM) , Shot Matching, and a partnership with John Carpenter to unify coaching—creating a Higher Resolution with the Advanced Tennis Foundation, endorsed by Johan Kriek in Modern Tennis Instruction.

John B. Carpenter
Coach
John Carpenter, from East St. Louis, Illinois, grew up collecting baseball cards, comics, and tennis books. At 15 years old, coaches told him to stop jumping on open-stance forehands, leading to a decline in his game. Shifting focus, John aimed to become a master coach, collecting hundreds of books and studying tennis theory from Tilden to Braden.
In 2003, he tested a contrarian method and quickly built a waiting list of students. In 2004, he partnered with internationally renowned coach Oscar Wegner to reform tennis instruction. In 2007, John and Wegner co-founded the Modern Tennis Methodology Coaching Association (MTMCA) . In 2016, John's research led him to a new frontier—partnering with unifying Atlanta coach Chuck Tomlin to continue evolving tennis instruction.
