About Us

We are a company based in the United States. International Soccer Concepts was founded by Ricardo Guerra, a professional with vast experience with the game.

Ricardo Guerra

Ricardo was the exercise physiologist for Olympique de Marseille during the 2015–2016 season, during which they reached the final of the Coupe de France.  Among other leagues in Europe, he has worked in Portugal and Spain.  In addition, he has tested several teams in South America and Africa and has served as the exercise physiologist for the Egyptian and Qatari national soccer teams.

Ricardo has been a lifelong student of the science, sociology, and psychology of the game, holding not only a master’s degree in exercise physiology from Liverpool John Moores University, a pioneer in researching the science of soccer, but also two coaching licenses, the UEFA B license—one of the two highest soccer-coaching licenses in the world—and the International Coaching License from the English FA. He has also studied various pedagogical methods in order to determine the most effective ways to improve young players’ skills. Ricardo has written extensively about the game, and his articles have appeared in national newspapers and magazines in more than five different languages.

Our Philosophy

Our philosophy has been influenced by many different thinkers. In our classes, we synthesize the Dutch, Brazilian, Argentinian, French, and Spanish soccer traditions, and the Coerver Method is fundamental to our teaching philosophy.

We are a lean, compact, and robust family-owned company. We believe that our tight-knit nature—and everything that flows from it—is our biggest strength, allowing us to maintain the high quality of our services.

Whereas bigger franchises and corporations tend to follow a one-size-fits-all approach, our size allows us to offer high-level, specialized boutique services. We offer a limited number of events yearly, ensuring that every one of them will live up to our high standards. Furthermore, while it is unlikely that larger companies will be able to staff their venues with elite coaches and players, at our programs and camps, we employ coaches who possess the highest licenses in the world and bring some of the greatest soccer players past and present to coach or demonstrate various technical and tactical aspects of the game.

Our family-owned spirit also leads us to give back to the community. At each of our camps, we offer a number of spaces for participants who cannot afford the cost of admission. On top of that, we also donate a certain percentage of our profits to charity.

The Board

The purpose of the board is to systematically review our services. All services offered by our company are continuously checked, critiqued, and perfected whenever the board determines there’s a need.
