Testimonials

Stephen Koon was part of the IMG-Bollettieri Tennis Academy for several years and was a very important part of working with potential players that have talent to play for colleges on scholarship or to be a professional on either the WTA or ATP tour.

Stephen’s work ethic is very simple: give 100% and then more to whomever you work with. His morals and character are of the highest degree and this is a major plus for him because our young athletes are in need of guidance.

Not only did he travel with our players but he was also very prompt in sending daily reports or calling in to discuss any matters at hand. It is not that often that I write this strong of a recommendation, but Stephen Koon is exceptional and I personally endorse him

I wish I met him earlier in my career. Stephen made me see tennis from a different way. He brought a lot to my tennis and made me feel very different. I deal with pressure, see opponents weakness better, manage my emotions better and these things help me stay in matches and enjoy the matches. We are a good match Cos we both like to work hard

If you come to Impact be prepared to work hard. They are very honest coaches, they will tell you what you need to work on what you need to improve on and they will give it to you straight. So come with an open mind and come to improve and work hard and there’s no question you will improve and be a better player when you leave from here

“Stephen is one of the sincerest and hardworking coachihave worked with He promotes dedication and discipline in the player that he works with.”

I have known Steve for a long time, since I was a junior. I really appreciate him, he has given me a lot of good advice over the years

I met Steve when I was 15 years old in IMG academy he took me on the ITF circuit including clay in South America. After he left IMG we stayed in touch and later I did a preseason with him at IMPACT Tennis Academy Thailand in 2017.

In 2018 I won my first ATP title
During my junior time I was just coming back from injury so I was having a tough time, but Steve helped by teaching about perspective, how to keep improving, believe in myself and stay professional.

I was young, so my mentality i was up and down but Steve supported me a lot. Even though he was tough I realize now how important it was to have that influence as a junior.

I have great memories with him. He’s not just a coach, but a friend even until today and I look forward to being a uncle to his daughter

Stephen is intense and funny, you need that. He is a great coach

Stephen likes to train you very hard and that’s great for the kids and why we like him. He pushes you to your limits and really helps you.

“ตลอดเวลาที่เล่นเทนนิสมา ผมได้มีโอกาสเรียนรู้จากโค้ชทั้งคนไทยและต่างชาติมากมาย แต่สตีฟเป็นโค้ชที่ไม่เหมือนใคร สิ่งที่สตีฟพูด เค้าไม่เคยตำหนิใครเพียงเพราะว่าโมโห ไม่ชอบ หรือไม่อยากสอนนักกีฬา เค้าเป็นโค้ชต่างชาติที่ทุ่มเทกับการสอนมากคนนึง สตีฟเป็นโค้ชที่แตกต่าง แต่ความต่างนั้นทำให้ผมเห็นเทนนิสในมุมมองที่ผมไม่เคยเห็น สิ่งที่เค้าสอนดีต่อเด็กที่มีวินัย มีความขยันและรับฟังความรู้ใหม่ๆ เค้าไม่ใช่โค้ชที่พูดอ้อมค้อม หรือโค้ชคอยให้ท้ายนักกีฬาในทุกๆเรื่อง เค้าเป็นคนตรง ที่เมื่อเห็นจุดบกพร่องนั้นจะพูดออกมา แต่การพูดออกมาของเค้าจะไม่พาดพิงเกินเลยมากกว่าในสนามเทนนิส ทุกครั้งที่ออกมาจากสนาม ผมสามารถมั่นใจได้ว่าไม่มีอะไรทำให้เราไม่ชอบกัน และไม่อยากฝึกซ้อมต่อด้วยกัน ผมชอบในความตรงไปตรงมานั้นของเค้า เพราะนั่นทำให้ทุกฝ่ายไม่เสียเวลาอันมีค่า สามารถแก้ปัญหาและมุ่งหน้าไปต่อได้”
