Introduction: The Clues Are Everywhere
Success in elite sport is not an accident. It is the byproduct of structure, clarity, environment, and long-term vision. Having spent the past 20 years working at the highest levels of sport and business - which have included junior/pro tennis to the NBA to leading the Gatorade Sports Science Institute, an executive at a Fortune 50 company and most recently at the largest wellness resort and healthcare company in the US I’ve learned one truth: success leaves clues.
This article is a historical perspective, but also a blueprint. It's a reflection on what works, what doesn’t, and what sports federations, associations, businesses around the world can learn from a pivotal era in U.S. tennis development—one I had the privilege of living from the inside.
The renaissance of US tennis is something that can and should be studied across sports. It is one of the best examples of a turn-around from a historical powerhouse, who lost its way (from a results perspective) and was able to turn things around to become the most dominant tennis playing country at the professional level. Many factors contribute to a turn-around of this magnitude, but some obvious and clear components can be learned and utilized for any organization or federation looking to be the best in the world.  

At the lowest point in 2008 US Men had 6 players in the Top 100 and US women had 4 players in the Top 100. As of Wimbledon 2025, US Men had 14 men in the Top 100 and the US women had 16.

But before diving into the institutional details, I want to share how I got here.


My Foundation: From Court to Clinic to Campus
I was fortunate to be a high-level junior player, competing in multiple Junior Grand Slams, including the U.S. Open and Australian Open. One of my favorite memories was playing doubles with Andy Roddick at the Junior U.S. Open. To this day, I thank him for taking the court with me. That story deserves its own article. Andy was a hot shot junior player from the US; he was younger than I was and was a year away from having his major breakthrough. He was travelling at the time with his coach Stanford Boster. I was playing Mardy Fish in the US grasscourts in Philadelphia a few weeks before the US Open. I was a lefty who volleyed well and new how to play doubles - after the match Stan came up to me and asked if I wanted to play doubles with the other player he was coaching – Andy Roddick. We said we would play the Canadian Open and the US Open together. Once we got to the US Open the USTA was putting pressure on Andy to play with another US player. I totally understood, but to Andy’s credit, he said we had made a commitment to play with each other and he wanted to honor that. To this day, I always remember how he stuck with this decision, which at the time was not easy.

After juniors, I played college tennis at Auburn University where I became an NCAA Champion in doubles, All-American, and was named National Doubles Player of the Year. I was dealing with a lot of shoulder issues and that is what got me into the career that I eventually was lucky enough to have. Yet, those very injuries propelled me into my life's mission. I became obsessed with understanding performance, recovery, injury prevention, and how to train smarter. I earned my PhD from the University of Alabama and was trained in sweat and blood labs as a clinical researcher. This training was strict and focused on the details. Dr. Jeff Chandler, a respected scholar and long-time Editor-in-Chief of the NSCA Strength and Conditioning Journal, gave me my first opportunity to be a professor and researcher. I thank him for this major step on my journey.

It was with Dr. Chandler that I gave my first professional presentation in tennis sports science  at the Professional Tennis Registry Conference in Hilton Head. That moment solidified a vision: I was going to spend my life helping individuals improve performance, health and wellness using science-backed concepts. Dr. Chandler helped connect me with the USTA initially and Dr. Paul Roetert was the individual that hired me at the USTA in 2008.


A Defining Moment: USTA Player Development, Circa 2008
In 2008, I joined the United States Tennis Association at a critical inflection point. The USTA had recently relocated its training center from Key Biscayne to Boca Raton, Florida. The organization had bold ambitions but was facing harsh realities. American tennis was at its lowest point in modern history. The number of U.S. players ranked in the ATP and WTA Top 100 was at an all-time low.

This prompted major leadership decisions.

Many people contributed to the decisions, but one person who rarely gets enough credit is Gordon Smith. Gordon was a tennis player (collegiate star at University of Georgia) who had a first career as a prominent attorney in Atlanta and was a major volunteer for the USTA. He then transitioned from his legal career to become the Executive Director of the USTA. Without his leadership and willingness to make some significant and difficult decisions, the plight of American tennis may have been very different. Patrick McEnroe was brought in as the new General Manager of Player Development. One of his first strategic hires was José Higueras - former coach of Roger Federer, Michael Chang, and Jim Courier—to lead the coaching vision. José left coaching Federer to join the USTA. That’s how committed he was to reshaping American tennis.

It was a pivotal and controversial moment. The USTA was no longer just a supplemental entity. It was becoming an academy—training players on-site, year-round, with a singular goal: produce the next generation of great American champions.
 
The Core Idea: Excellence as a Non-Negotiable Standard
What made this era so transformational wasn’t just the shift in logistics—it was the shift in mindset.

The mission was clear: everything we did - every hire, every program, every camp - had one purpose: help players succeed at the highest level of professional tennis.
This laser-focus on excellence gave clarity. We didn’t try to be everything to everyone. Some people who didn’t buy into the high standards were upset, some people who were not at the level felt it was too hard. We weren’t running summer camps. We were focused on building professionals who could compete and ultimately beat the best in the world. And that clarity influenced every layer of the program.

It also led to inevitable friction.

Some people didn’t like the intensity or the singular focus. Some had to leave. Others stepped up. And those who stayed understood the commitment it would take — not just from the players, but from the staff, coaches, parents, and support system around them.
​Creating a Cohesive Philosophy: Downloading José Higueras
One of the most important projects I worked on during this time was helping José Higueras translate his vision into a codified philosophy. José is a brilliant coach. But like many great minds, his knowledge wasn’t written down - it was lived, practiced, and spoken. One my jobs was to “download his brain,” turn his coaching ethos into a teachable framework, and create consistency across a national system.

What emerged was a set of principles, not a playbook. We didn’t want to script creativity out of coaching. But we did need alignment—shared language, shared standards, shared expectations. It became known as the "Philosophy".

And the key principle was this: treat every player like they’re going to be a world-class professional until they prove otherwise.
This philosophy emphasized:
  • Competitive environments
  • Daily excellence
  • High physical and mental standards
  • Clarity in communication to parents and coaches
  • Responsibility and accountability on the part of the athlete


The Listening Tour: Earning Trust Across the Nation
One of the smartest decisions made early on was to engage directly with the tennis community across the country. Patrick McEnroe, José Higueras, Martin Blackman, and I went on a national listening tour.

We visited USTA sections, academies, and coaching networks. The feedback was blunt, passionate, and - long overdue.

Coaches felt isolated. Parents were confused. There was no cohesive national strategy. But what we discovered in every city was encouraging: dedicated coaches who deeply cared. A passion and dedication to getting American tennis back on top.
These sessions weren’t just data collection—they were relationship-building moments. And they seeded something critical: trust. It was awesome to have the legends of the game involved like Robert Lansdorp, Nick Bollettieri, Rick Macci, Chuck Kriese, but it was also great to have so many of the coaches who have developed great players over many decades like the Smiths in Indiana, Ernie Peterson in Atlanta, Vesa Ponkka and JTCC in the DMV, Margie Zesinger and Juan Herrera at IMG Academy, John Wilkerson in Texas, Trent Tucker in Tulsa, Dave Licker in Texas, John Hubbell in California, Walter Sahag among so many others. I am sorry as I know I have left out so many fantastic coaches.  Hundred of coaches came to share, to learn to criticize and to provide perspective. All was valued and needed. It made the country better.
 
We began to unify a fractured coaching landscape by being honest, transparent, and inclusive. That laid the groundwork for one of the most impactful innovations: the Regional Training Center (RTC) model.


The Pipeline Solution: Regional Training Centers
The RTC model, led by Martin Blackman and supported by leaders like Kent Kinnear and Geoff Russell, became the cornerstone of player identification and development, but more importantly coach identification and development.
Each of the 17 USTA sections was supported by an RTC that hosted camps, player evaluations, and coach and parent education. The goals were:
  • Expose young talent to national standards
  • Provide actionable feedback (e.g., video analysis, physical assessments)
  • Connect national staff with local coaches
  • Elevate coaching relationships
  • Educate parents on the top of the funnel and what it takes to become the next great American Champion
The camps weren’t just about players. They were about coaches.
Private coaches were invited to participate. They were treated as faculty. They felt part of the mission. This was a major shift - and one of the reasons the system eventually gained traction. This was never intended to be a national run program, it was designed to integrate with the coaches in the sections and have it be a collaborative approach to developing Champions. We were saying: "You're the most important part of this."


National Camps: Precision and Purpose
Our national camps became another key building block of the development system. These were run with military-like precision - lesson plans down to the minute, video sessions, fitness evaluations, and structured on-court training.
Many tennis coaches are instinctive and free-flowing by nature. So early on, some resisted the structure. But it was necessary. We had to show what “elite” actually looked like - hour by hour, drill by drill. Early on every court was doing the same drill at the same time. It was a highly regimented model. Looking down the courts in Boca Raton at 9am on a Thursday of a camp you could see 8 courts of X drills being done. It was one heck of a site to see. Over time this regimented model was loosened after the staff and coaching teams were fully educated and aligned on the philosophy and the systematic approach could allow for a little more creativity. However, this process was so needed, and just like great NBA coaches, NFL coaches and business CEOs need a philosophy and system, this was the new US tennis system.

Key characteristics of the camps:
  • Movement-focused sessions, not just technical instruction
  • Strength and conditioning integration
  • Hand feeding and close coach-player proximity
  • Culture of hard work, intensity, and team accountability
  • Not a talent showcase - an effort and attitude lab
  • Searching for the players that loved the game, where great competitors and had the capacity to do what was required to be a top professional
From 2009 to the early 2015, nearly every major American pro came through these camps—Coco Gauff, Taylor Fritz, Madison Keys, Sloane Stephens, Reilly Opelka, Frances Tiafoe, Jennifer Brady, Tommy Paul, and many, many more.

The camps didn’t make them great. But the camps brought the best players together and helped many players understand the level and provided opportunities to train with the best, win and lose against the best and these cohort effects are so important in greatness. We see it all sports and great periods in history. The cluster effect of having a group of players who can push each other makes the best better. 

​The Coaches: The Unsung Heroes
We often talk about players. But what truly made this era special was the coaching ecosystem.

At the national level we had world-class minds in one room every day. Former Top 10 players. Davis Cup captains. Grand Slam champions. Challenger warriors, junior development experts.

The daily conversations were electric—strategy, technique, footwork, spin, pace, mental toughness, travel, life and even backgammon. Every topic was on the table. Every opinion was debated. But the common thread was this: everyone was there to make players. The passion was real. There was no clock. No 9am to 5pm. The best discussions were at a junior tournament at 10pm in the hotel lobby after a tough loss, or waiting at an airport after a 4 week trip to Europe grinding on the clay against bigger, stronger and older athletes and finding ways to win. Passion was the secret ingredient.

My greatest memories were sitting in these coaching meetings and debating about strategy, tennis footwork, scheduling and just about anything else to help us all get better. Imagine being a room talking tennis debating with the following:
  • Jay Berger – Former ATP Top 10, insightful and passionate leader
  • Ola Malmqvist  - Former collegiate great and 40 year career coach with some of the best in the world.
  • Tom Gullikson – U.S. Davis Cup captain, veteran strategist
  • Andy Brandi – Junior development legend
  • Craig Boynton – Top pro tour coach and road warrior
  • Stan Boster – Developmental genius on the junior-pro bridge and a road warrior
  • Diego Moyano – Claycourt specialist with Challenger grit
  • David Nainkin – Steady, elite builder on the West Coast who has touched nearly every great Californian player over the past two decades
  • Kathy Rinaldi -  legendary person and presence. She makes everyone better. Every player and coach that works with Captain Kathy gets better. Including me.
  • Lori McNeal – the best athlete in the group. Had so many great conversations on women’s tennis.
  • Jamea jackson – first as a player turned into a great coach. The passion is real
  • Leo Azevedo – claycourt specialist who brought a different perspective
  • Brad Stine – legendary tour coach and always happy to debate any topic   
  • Kent Kinnear – The listener and relationship expert
  • Patrick McEnroe – Kept the focus on the real thing. Brought much needed NY attitude
  • Jose Higueras – Always asked what do you think, but always knew what he thought and wanted
  • Martin Blackman – understood the bigger purpose of developing people and players
  • Dustin Taylor, Andres Pedroso, Mark Merklein, Mike Sell, David Roditi, David Dilucia and so many more great coaches who attended or participated for short periods of time.
  • David Ramos, Geoff Russell, Paul Lubbers, Jose Cabellero all were hug pieces of the puzzle from a coach education, parent education and systems perspective. The coaches needed glue to keep it all together and these individuals provided the glue.
  • An entire team of physical trainers, physios and sport science staff including Satoshi Ochi, Brett Waltz, Rodney Marshall (among others) to help provide so much support to players, coaches and parents.
This was not a passive environment. It was intense. But that’s what high-performance should be. It was a privilege to be part of it.
The US is so large that the private sector coaches were and always will be the driver of long-term success of the countries tennis aspirations at the professional level. The collaboration with national staff will always be the greatest opportunity and also the biggest challenge at the same time. The ecosystem that was developed allowed for more contact, greater alignment and more opportunities to help coaches in the private sector and more importantly learn from the coaches in the private sector. True high performance is really hard, as it requires support across the tennis ecosystem.


Creating a National Identity
All of this - philosophy, camps, coaches, communication - contributed to something larger:

This created a national identity for American player development.


We moved from fragmentation to unity.

We moved from hoping players would emerge… to helping to build them.
​
And although no system is perfect, this was the first time in decades that U.S. tennis had a clear pipeline, a defined philosophy, and a unified purpose. It certainly was not perfect, but it was clearly defined, and it provided a stake in the ground. The timing required this stake in the ground and although many factors contribute to pro tennis success, the data and numbers clearly show that what was implemented correlated clearly with the resurrection of tennis success in the US. 

Establishing the First Data-Driven Player Pathway Framework
One of the foundational projects I was asked to lead was developing and overseeing the first comprehensive Player Pathway Study. This research initiative was designed to bring objective clarity to the developmental process.

The study analyzed multiple decades of longitudinal data on junior, collegiate, and professional players to uncover key trends in age, ranking benchmarks, tournament progression, and common timelines for success on the ATP and WTA Tours. It was the first time this type of evidence-based research had been used within the USTA to inform strategic decisions.

Over the next decade, the findings became central to USTA Player Development strategy. The data influenced:
  • Player scheduling and training plans
  • Grant and funding decisions
  • Evaluation criteria for developmental progress
  • Coach and parent education initiatives

This project helped shift the organization from anecdotal decision-making to a more data-driven culture, aligning national strategy with performance realities and creating more individualized and predictive development models.

​
Lessons for Federations Around the World
Having since worked with other sports (basketball, baseball, golf and soccer), professional leagues, and global performance institutions, I’ve seen many federations face the same challenges. The lessons are universal.
  1. Clarity of Mission: Decide what success looks like and build everything around it.
  2. Central Philosophy: Develop a shared language and teaching framework.
  3. Coach Empowerment: Treat coaches as partners, not replaceable assets.
  4. Regional Development: Create scalable, local hubs for national impact.
  5. Standardized Feedback: Use objective tools (testing, video) to educate players and parents.
  6. Culture Over Curriculum: The environment shapes the athlete - make it elite.
  7. Expectations: Raise them, expect them and focus on them everyday


Final Words: The Clues Are Yours Now
My journey through the USTA, and beyond into the NBA and Gatorade Sports Science Institute, has always come back to one truth:

If you want to build greatness, you have to design it.


It doesn’t happen by accident.

Success leaves clues. The blueprint is available - for any organization or sports federation willing to commit to structure, clarity, and excellence.

The next generation of athletes is waiting.
 
All the best,
