Our Ethos
“If you know the way, light it for others”
We strive to continually help and support the global community of racquet technicians. To that end, our website is strategically designed to give every racquet technician the tools they need to become the very best he/she can be. Our online stringing courses are rich with in-depth written material however, we feel the best way to learn is by seeing, and therefore, the courses are packed with videos to visually enhance your learning. KAIZEN
No one has written the handbook on racquet service and that means there’s always room to improve, to learn from one another and to grow together. One approach to continuous, incremental improvement is called kaizen. It originated in Japan and the word translates to mean change (kai) for the good (zen).

About Us

He has a background as a teaching professional with both the USPTA & PTR and from 2000 to 2008 he worked as a professional racquet technician on the official stringing teams at various ATP/WTA events including Wimbledon, the U.S. Open, and the Sony Ericsson Open in Miami.
Course Reviews and Comments from Our Happy Clients
IART is dedicated to empowering individuals globally to elevate their expertise as racquet technicians, alongside catering to local players in our local community. Curious to hear what they have to say about us? Explore their testimonials today!
Tim is a great help to the players at our camp. The average tennis player has no idea of the importance of equipment management. In tennis your racquet is your weapon. You cannot expect to perform if your weapon isn’t balanced, weighted correctly, strung properly and suites your game. Tim delivers exceptional service and guidance for managing your equipment as well as enhancing your play through your racquet having the correct specifications. This is important at every level but it’s really important when you are rotating racquets and breaking strings on a regular basis at advanced levels of play. He not only handles things for us locally at the camp in Virginia he also works with our players when they are traveling playing events all over!

Brenda Schultz McCarthyCo-Founder at Brenda Schultz Sports Camp & The T.E.D.S. Foundation
I first met Tim in 2006 when he came and helped train over 40 Professional Tennis Management students at Methodist University about how to handle and string natural gut the proper way. It was clear at that time that his vast experience and knowledge made him one of the leading stringing experts in the field. It was after that initial meeting that I started attending the IART symposium (formerly GSS). This event truly helped mold my career path allowing me to learn essential stringing and customization skills, understand product development and even more importantly network with some of the most influential stringers in the world. If you are interested in learning how to string, opening a stringing business or even becoming an elite tour stringer there is no better place to learn and network with key people in the stringing world than the IART platform.

The IART has been a major influence to the stringing community over the years. I’ve seen attendees from the symposiums go on to string at multiple Grand Slams. IART is a great place to learn, share and network with IdmKuyhaa stringers all over the world.

I am very happy that I joined and would highly recommend joining IART. The membership fee is a small price to pay for a service that provides past, current and new information plus advice regarding our industry. My goal is to always listen and learn more about new (and old) techniques and products. Thank you Tim for all your time, effort and wisdom so far.

The International Alliance of Racquet Technicians (IART) is a global organization dedicated specifically to the racquet service side of the tennis industry. Our primary focus is to unite racquet technicians from around the world who have a true passion, love, and dedication for the craft of racquet service.
Our string characteristics data base provides you with a quick reference for determining what string to use for your clients. Numeric figures from actual bench tests are provided for elongation (higher numbers=softer string) and tensile strength (how durable is it). Easy sort functions allow you to sort 6 different string types; Nylon, Multifilament, Natural Gut, Polyester, Kevlar & PEEK. You can also sort specific manufacturer strings (what’s the softest Wilson string we tested), or select “All” to sort the entire list (what’s the softest string we tested among ALL manufacturers).
Our stringers directory is one of the most unique member features offered anywhere within the industry. If your interest is tournament stringing or you would like to make yourself available for special events you have the option to submit your profile to be listed in this data base. We will then promote this list to tournament directors and special events coordinators.
List your business profile here and we’ll make it available to the public via the main navigation link “Tennis Shops in Your Area”. Listing your business profile here will give you International visibility to attract new clients. Think of this as a 21st century yellow pages
Locating that “hard to find” B/G set can be a real challenge. As an IART member, you can list your available B/G sets here and sell them to the public. Only members can list their B/G sets but the list is accessible to the public.
We offer a very unique format of stringing machine reviews that provide data to help you make the right choice the first time when buying a stringing machine or a piece of diagnostic equipment. Example: Mounting systems are rated to clearly show how well a specific machine holds the racquet in place during the stringing process.
