What About Me?
A lifetime dedicated to racquet technology and innovation
For more than five decades, I have been immersed in the world of tennis racquet and string design, manufacturing, and performance optimization. As the owner of Racquet Quest, LLC, I’ve combined deep technical expertise with hands-on innovation to set new benchmarks in racquet customization, diagnostics, and stringing.
My journey has been defined by a relentless pursuit of precision and performance—whether with professionals, college, junior tournament players, in the lab, or in front of an audience, sharing knowledge with peers.
Advanced diagnostic technology
At Racquet Quest, technology and science drive results. I’ve integrated some of the most advanced diagnostic equipment available, alongside proprietary systems I’ve developed, to provide unmatched insights into racquet and string performance:
- True Tension Stringing Machines – pioneering distortion-free stringing
- Babolat Racket Station & Wilson Baiardo Stringing Machines – industry-leading accuracy
- Babolat RDC (Racquet Diagnostic Center) – comprehensive racquet analysis
- Questron proprietary string testing equipment – measuring ultimate tensile strength, stress/strain, knot strength, and more
- Three-string comparative graphing tools – side-by-side performance visualization
- Flex, In-Plane, and String Bed Stiffness devices – quantifying structural dynamics
- Custom portable SBS device – portable precision testing
By combining these tools, I’ve been able to capture and refine the delicate balance between tension, elasticity, and structural integrity, pushing racquet performance beyond traditional standards.
Innovation in design and customization
Innovation has always been central to my work. Some of the highlights include:
- Development of the Perfect Pallet grip system with a custom three-piece anti-vibration design
- Expertise in Special MakeUp (SMU/Pro Stock) racquets for elite players
- Custom racquet extensions and modifications tailored to individual needs
- Proprietary software solutions for collecting and analyzing racquet and string performance data
These advancements have helped players—from juniors to professionals—experience greater consistency, comfort, and control on court.
Experience on the global stage
- My expertise extends well beyond the workshop:
- 50 years in racquet and string design and manufacturing
- Professional event stringing services for several years at major tournaments
- Seminar presenter for 12+ years, sharing expertise with players, coaches, and technicians
- Delivered the acclaimed session “Understanding String” at the 1994 Super Show in Atlanta, hosted by the United States Racquet Stringers Association
This combination of hands-on service and educational leadership has helped shape best practices across the racquet service community.
Media and knowledge sharing
I believe that expertise should be shared widely. To that end, I’ve created multiple platforms to bring racquet knowledge to players and enthusiasts worldwide:
- RacquetQuest.tennis – a hub for insights and resources on racquet technology
- Racquet Quest Podcast, Podcastini, and Podcast Midi – covering everything from string science to on-court trends
Through these channels, I aim to make the science of racquets accessible to every level of the game.
⸻
Tennis continues to evolve, and so does racquet technology. At Racquet Quest, I remain committed to research, testing, and innovation that give players an edge while deepening their understanding of how equipment shapes performance.
Whether stringing for professionals, customizing for serious competitors, or educating the next generation of racquet technicians, the mission remains the same: deliver precision, performance, and passion through technology.
Questron Cycle Update
Every string that enters the World Headquarters of Racquet Quest goes through the Questron cycle. We have posted images of the product of the cycle, but not the entire process that the Questron goes through to create these posts.
The following video is the entire process from start to post. We look forward to your comments!
If you have a string, or strings, that you would like to know more about, please let us know. We may have already put them through the Questron Cycle.
I mistakenly said “Z” axis when I meant “X” axis, if you caught it.
Comfort is the new Soft!
Over the years descriptive terms for tennis strings have endured many mythical, and even wrong, definitions.
One of the terms we continue to hear is “Synthetic Gut”. First of all, in terms of tennis string if the material is not from a once living animal it is “synthetic!” The term “synthetic gut” was responsible for relegating “nylon™” to the very lowest of low end tennis string, however, even today Nylon™ makes up a substantial percent of the tennis string material!
Now comes “Comfort” trying to relegate “Soft” to the scrap heap!
What difference does it make? A lot. Seasoned players know what works for them and they don’t care what anyone calls it. On the other hand those just beginning or wanting to improve their game do care.
With our in-house testing device, Questron, we test every string that goes into a racquet, and every string that comes into the World Headquarters . The graphs have been posted on this site a few times but just in case you missed them here is a graph:
This graph represents two (2) polyester strings and one (1) natural string because it was handy.
In the simplest terms the quicker (shorter deflection) the string reaches 50 pounds the “stiffer” or less “soft” it is. Neither of the polyester stings are “soft” compared to the natural string, however, one polyester string is “softer” than the other polyester string but not by much.
We have tested many strings that are now available in a “soft” version and the “standard” (not soft) version.
Whatever string version you choose use it because it works for you whether is it marketed as Comfort or Soft!
