How Dr.Karl Lee Founded Adaptive Tennis US

Upon graduation from Tufts Dental School in 1982, I thought that I would be a dentist for the rest of my life.  I realized later that life brings many turns to the long road of living.  I asked one of my patients who was wearing a shirt that said “Gerry Hattricks” what was the meaning of the term. I found out that it was a hockey group organized to allow disabled veterans a chance to play hockey.  Naturally being such an avid tennis player and fan, I wondered if there was such a group for tennis. He replied that he did not know of any in the area, so I decided that I had to create an organization that would help the veterans learn the game that I loved. 

As the Wounded Warrior Tennis group continued to operate, I realized that there many more people who would benefit from our services, people who had a developmental disability, those who suffered from traumatic accidents, people of different cultures, those who did not have use of one or more of their sensory tools.  The platform of tennis can be a tool for allowing others to discover the potential within themselves, to build self confidence and motivation. Hence the eventual emergence of Adaptive Tennis US

Why Support Us?

The contributions donated to Adaptive Tennis US help to support and sustain the tennis training programs by purchasing court time, equipment and tennis instruction, which engage the participants in a positive social environment, reaffirming their sense of confidence and self worth.

Why Do We Exist?

Mental health issues are prevalent amongst those who feel isolated, which can lead to severe depression and suicide. Adaptive Tennis US strives to utilize the game of tennis to help those who feel disenfranchised to gain a sense of belonging, and to develop the confidence within themselves to better reintegrate within society.  

What We Do

Our organization teaches the game of tennis from the incipient novice to the advanced player, treating each participant as an individual with specific adaptive requirements. We use a program that involves a warm up segment, stroke mechanics, and game play; all involving positive reinforcement. 

How We Make A Difference

As our participants engage in the game of tennis and become more capable, they learn that no challenge is insurmountable, and will find ways that work for them. Hence, the lessons learned on the court, translate well into the greater aspect of public life, where everyday challenges may seem daunting.

How Our Work Is Different From Other, Similar Charities

Our organization is led by a certified uspta tennis pro (2006) who is also a certified personal trainer through the National Strength and Conditioning Association (2018). Furthermore, he is a certified tennis performance specialist (ITPA) teaching tennis from a biomechanics basis (2018). Dr. Lee has obtained a certification as a Corrective Exercise Specialist, through National Association of Sports Medicine (2020)

What We Have Accomplished

We have worked closely with the Warrior In Transition Brigade, as a part of their physical / activity program to reintegrate the transitioning military personnel into civilian life. Many of these veteran soldiers have benefited from our program with a renewed sense of confidence and belonging. 

How You Can Be Sure That We Will Use Your Donations Wisely

The donations received from the public will serve to engage adaptive individuals who may suffer physically, emotionally, cognitively, socially or developmentally. We do not discriminate in the acceptance of our players and all are welcomed.  On the AdaptiveTennisUS.com website we publish the coverage of our players and show their accomplishments.
