Thoroughly enjoyed the course. Good for my confidence.

I recently finished the Advanced Racquet Stringing course offered by IART. I found the course very good. Actually, having attended IART Symposiums in the past this was almost like attending one. The upside to taking this course is you can get every lesson offered instead of having to pick and choose classes. All the modules are carefully presented and flow nicely from beginning to end. I’ve been stringing for many years, and I suppose you could say that I’m very set in my ways. But this course kept my attention, and I couldn’t wait to get to the next module after finishing the previous one. You never stop learning!
I used information I learned this past week dealing with a customer and I was able to explain the issue in a way which made me stand out as a professional. I have a customer that will be coming back with more business! Did I say, “Value Added”? Thank you IART. To anyone that signs up for this course you will find great instructions, tips, and ideas that will make you a better stringer. From beginning to end you will absorb valuable knowledge regarding machines and tools, string, stringing tips, patterns, tools, plus merchandising and customer relations. The videos are a wonderful addition to further the written lessons, and I strongly recommend to anyone taking the course to take the time to view them all. Not only do they add to the written lessons, but you will probably learn additional things just from watching. The test questions were prepared from each module and thought provoking. Study the module and read the test questions (maybe twice) and think before you answer. Actually, the questions are there to make you think and that’s all part of the learning process.

Thank you, Tim, for your efforts to help make us all better in our stringing business.

Knowing your “base” is a great way to start advancing in anything, and this course does exactly that. You lay a base of knowledge that pushes your curiosity to learn more. After the Basic Stringing 101 course, you are perfectly set up to move forward in your profession.

Love the closer views on stringing tips. More useful tips on various weaving methods and ideas on racquet maintenance. Loved the business ideas too.

Excellent course! A true soup-to-nuts magnum opus on all things stringing and stringing related topics. It really brought all the aspects of string, stringing, rackets and racket customization together in a modularized format that was easy to follow and comprehend.

Well done!

Exceptional service is the hallmark of a great business, and exceptional service is impossible without exceptional knowledge. The information in this course will provide you with the expertise you need to advance your business to the next level and beyond. I always try to learn new things, and this course showed me a few things I had forgotten, and instilled some new knowledge I’ll definitely use to help my business. Taking this course was like being at an IART symposium where the knowledge comes from decades of experience and allows you to be confident you know what you are talking about in some sections while showing you the right things about those where you are weak. Well worth the time and money for anyone wanting to advance in their craft.

Major thanks to Tim and all the IART Ambassadors for their dedication to the craft of racquet service!

“My name is Luiz Machado. I’m a recreational tennis player, and after many years without playing, I started playing again a few months ago. I already had an old racquet and went to a local store to change the strings. I was surprised and a little confused by the number of string and racquet options available. Then, I realized how outdated I am. I started researching and watching tutorials about racquets and strings. I found a lot of information, but there wasn’t a place that taught solid fundamentals. On a YouTube channel, I discovered IART’s Basic Tennis Stringing 101 course and it was what I needed. The course is very well designed, with essential information for anyone who wants to learn how to correctly string a tennis racquet. All the necessary basics for the student to begin the activity with confidence and security are explained in theory and demonstrated in very educational videos. Instructors demonstrate extraordinary knowledge and skill. The learning pace is very smooth and gradual, with no doubts left at the end of the sections. It’s a course I’m happy to have completed, and I recommend it to anyone looking for theoretical and practical knowledge about stringing tennis rackets. Thank you very much.”

Hi Tim,

I just finished Basic Stringing 101. I’ve been stringing for quite a while, but I can tell you I learned a lot taking this course. There are so many suggestions and different ways to accomplish and complete a racquet that really helps. I will definitely keep going back to review the videos. Thanks for all you do for us stringers.

Continued success,

Mr. Tim

Thanks for the in-depth training course! I found it to be excellent. A very nice refresher course, even for those of us with years of experience! You managed to jog my memory a lot. This would be a great course for all shops to train or retrain all technicians properly. The insight you gave was priceless, especially for me, coming after my stroke with some memory loss.  Again, thank you !!! It was very well done and easy to understand with all the why and why not of everything.

I took the Basic Racquet Stringing 101 Course offered by IART. In my opinion this is the best course that has ever been offered. During my many years of racquet stringing I have seen many “how to string a tennis racquet” videos, written articles, etc .. many not so good and some not good at all. I’m amazed at the time and effort that was dedicated to this project. The structure and content is presented in a way to keep the novice stringer and even those who have been stringing a long time anxious to keep learning and looking forward to the next section.

I highly suggest that anyone interested in learning the correct procedures of racquet service to take this course. Experienced stringers like me will be pleasantly surprised to pick up new ideas and procedures while following the studies. (You’re never too old to learn!)

To Tim and the other contributors, a big Thank You for your valued time and dedication to the stringing community.

The IART  has everything you need to successfully train and help you to become better at all parts of racquet stringing. It’s not just about stringing though. They cover all areas of racquet service with videos, interaction with other technicians, and information to keep you updated. A big plus is you have access to ask questions in their Q&A section to get answers from others who have vast amounts of experience. No matter where you are as far as your personal experience you can learn something new every day from the IART community.

The International Alliance of Racquet Technicians (IART) is an excellent resource for all stringers! If you’re learning the ropes and preparing to become certified, you can access all the stringing tips and videos shared by other IART veteran stringers. Maybe you’re a seasoned tournament stringer and operate your own stringing business. In that case, the monthly newsletters are a great way to stay in touch with the latest industry trends and valuable technical information. As one of IART’s Global Ambassadors, I always enjoy reading the articles that my colleagues post! But besides providing an excellent resource for all dedicated racquet stringers, IART has a unique interactive component. IART’s creator, Tim Strawn, has worked relentlessly since 2002, as it has evolved over the years. I look forward to the new website launch coming out soon!

By subscribing to IART, not only are you a member, you’re part of a community of passionate stringers who care about the art of racquet service.

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.

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!

My name is Mark Campanile and I am proud to be an Ambassador for the IART for many reasons. First and foremost, I have a great deal of respect for the founder of the site, Tim Strawn, because of his passion for the art of stringing, the game of tennis and his love of teaching and sharing his vast knowledge. Secondly, the IART site has a wealth of information on a variety of matters that pertain to racquet sports, racquet stringing and racquet & string technologies. It would be difficult to find a better site if you have an interest in learning more about the world of racquet sports, racquet stringing, racquets, strings, stringing machines and other professionals in the business. Check it out. It will be worth your time and investment!

Back in 2012 I attended my first IART Symposium and was energized by the range and depth of experience and knowledge from a group of experienced stringers, no more than 60 in number, from across the world, I have now been to a further 4 more symposiums run by the IART and having met Tim at that first symposium I joined the IART.
The ethos of the IART says it all ‘We exist to continually help and support the global community of racquet technicians. Our goal is to offer a comprehensive website for those in the service side of the racquet sports industry. To that end, our website is designed to help make every racquet technician become the best he/she can be.’
In my opinion the IART is succeeding in its ambition to meet its ethos. Without the IART I would never have come to know so many stringers that I now am privileged to call friends from around the world. Nor would I have had the opportunity to expand my knowledge from these friends and the many other stringers in the organization.
Finally, Tim has done a remarkable job in getting the IART to where it is now, and for those reading this testimonial that are not current members I would say, if you want to learn from the best then join the IART now!

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 stringers all over the world.

I just joined IART recently. Tim Strawn gave me a phone call right after I signed up and immediately made me feel like I joined a network of professional stringers that care about their members.
I have been able to speak with Tim twice after his initial welcome phone call and I was able to pick his brain about a few items. He is a veteran in our industry and he is very gracious and kind to share his great knowledge and wisdom that he acquired over the last few decades in the business of stringing and servicing racquets.
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.

Back in the early months of 2007, I was minding my own business as a teaching pro and racquet technician here in Central Florida when I came across a website called Grand Slam Stringers. There was a lot of content on stringing techniques, tournaments, etc, so I thought, “What the heck”, and signed up.
A little while later, I saw a post on a topic I was familiar with and shared my opinion. A short time afterwards, I got a call from this guy named Tim Strawn (who ran the thing) looking for more information on the subject and welcoming me to the group. It was a pretty nice touch, and Tim was quite enthusiastic about his project.
During our chat,I discovered Tim’s “ulterior motive”, as he brought up the subject of this little stringer’s symposium he was having in Texas later that year. I must admit I was reluctant at first: I’d been stringing for almost 30 years by then; what more could I possibly need or want to study about it, especially since it would require me to take off FIVE DAYS of work to do so?
However, Tim’s passion on the subject won me over, and I booked a flight to Texas, rented a car, and drove to New Braunfels (aka “the boondocks”), and took part in the first GSS Symposium. I met Tim soon after arriving, along with several of the seminar leaders, some of whom I had met, a few I knew by reputation, and many others I had no knowledge of at all. I found their dedication to their craft, and desire to teach quite enlightening, as I learned many things during those few days about knots, patterns, racquet design, business planning and tournament stringing that have helped me immeasurably since.
I’m sure I’ve left out a few things, but you get the gist: this was a GREAT learning environment, and everyone Tim recruited to help was top-notch. We even got a nice little “goody bag” with some string and grip samples, which became larger every year and wound up almost paying for the cost of the Symposium itself. I also met my friend Ron Castillo at that Symposium, and share with him the honor of being the only ones to attend all 10 GSS/IART Symposiums over the years.
I made many other friends through IART, some of whom I have shared many a late night over a stringing machine at tournaments, some that I have joined for many a drink, and one of which, Larry Hackney (“The Legend”), is dearly missed but never forgotten.
Being associated with IART has been a re-entry for me into the world of tournament stringing, as the contacts and relationships I developed allowed me the opportunity to work quite a few big-time (and big money) events such as the Eddie Herr International junior event, the World Team Tennis at the Greenbrier Resort and most recently, the Miami Open. Never underestimate the value of networking with groups like this.
Tim started a grommet strip selling section for IART members and I’ve sold over 100 sets of old grommet strips that were collecting dust in my shop. I’ve probably paid 20 years’ worth of IART dues from this service alone. The ability for consumers to locate a business on the IART site, along with exposure to tournament directors looking for stringers, proves invaluable to anyone in either profession.
I could go on, but I think I’ve made my point: the IART site is a great opportunity for anyone in the tennis business to learn and get the word out about themselves and their business. At $49 per year, it’s a steal, and I thank Tim for all he does for us on a daily basis.

In 2009 I attended an IART Symposium where I had a great experience. The symposium provided learning opportunities and a way to meet other racquet stringers. I recently joined IART where I saw an opportunity to get another perspective on stringing and also be able to connect with other experienced racquet stringers. A few years ago, I became much more involved in pro tour racquet stringing. Since, many IART members are currently or have been tournament stringers in the past, there is an opportunity to learn and share one’s experiences. Additionally, IART provides a great way to stay current in the tennis industry and more specifically with stringing techniques and product knowledge.
