Welcome! I'm Marcin Kosakowski, a coach with over 35 years of playing experience and more than 17 years of teaching experience. As an RSPA Certified Tennis Professional, I have had the privilege of coaching at the Westchester Tennis Center, the prestigious Mountain Gate Country Club, the Ritz Carlton Marina del Rey, and on the ATP Tour, as well as leading junior teams in the Westside Fall Junior League.                                                                      

Tennis has been part of my life from an early age - I grew up in a tennis family, competed nationally as a junior, and played collegiately at the University of California, Santa Barbara (#1 Doubles/#2 Singles) also held the #1 ranking in Souther California doubles and earned an ATP ranking, experiences that continue to shape my coaching approach today. 

I offer private, semi-private, group, and hitting sessions for player of all ages and skill levels. Whether you are a beginner learning fundamentals or an advanced player looking to fine-tune your tactics/strategy, I will create a personalised lesson plan to help you improve and enjoy the sport even more.  

Jenna is a former NCAA Division 1 student- athlete and two-year captain of the UC Irvine Women's Tennis Team (#1 Singles). Having played tennis since the age of five, she brings a lifetime of experience and passion to the sport.

Renard started playing tennis at the age of 11. As a nationally ranked player in the juniors he then went on to play collegiate tennis (scholarship) for Hampton University. He and his team won the NCAA division 2 title making Hampton the number one ranked collegiate team in the nation. After college I played around the world on the satellite and challengers professional circuit. After the world tour I went on to represent and play for one of Europe's strongest professional club teams in Germany for 10 years. Having retired from professional tennis I began a new chapter teaching others the sport I love.' I taught lessons in Germany and after several years moved back to the United States. I have been teaching tennis full time to all ages and skill level from beginners to nationally ranked players for over 30 years. I enjoy teaching all levels. I especially enjoy teaching beginners the fundamentals and a solid foundation they will have for the rest of their lives. Fluent in German.   

Coaching for me is about helping you reach your tennis goals. I believe in improving your performance as a tennis athlete first, with winning being the result of achieving your goals.

Our program challenges our students to strive for improvement in areas, rather than a “winning at all costs” philosophy. We also believe in working together with our students in a cooperative manner in which decisions are collaborative and the training structure is flexible.

You, the student, should feel that the lesson is uniquely tailored to you and taught by a trained professional who enjoys teaching and being on the court with you.
