Brent Mazza,

Director of Tennis

Hey! My name is Brent Mazza, and I am the Owner and Director of Tennis at HAT.  

Tennis is my true passion in life. I am originally from Southern California, but I went to college at Boston University, where I earned my

bachelor's degree in Business Administration. Prior to my time at HAT, I gained invaluable tennis industry experience working for the International Tennis Hall of Fame in Newport, Rhode Island, the Boston Lobsters' World Team Tennis Franchise, and for the Champions Tour. 

I started at HAT as our very first intern in 2010. Over the years, I progressed to assistant pro, head pro, and now director and owner. I am USPTA, PTR, USTA High Performance, and HAT Method Certified and have helped develop champions at every level. I have had the privilege to coach/consult with numerous Pro & ITF circuit players, and I have also had the honor of being selected by the USTA to coach several state, sectional, and national teams and events. 

My students call me "Mazza" and say that they enjoy my humor, but they know that I am also always honest and tell them the truth. They know that they can trust me. 


John Lutaaya,

Beginner Program Head Coach

Hi! My name is John Lutaaya, I come from Kampala, Uganda. Tennis has opened many doors for me and I am ready to do the best I can to help others with this gift of tennis. I graduated from Linfield University in Oregon in 2021, and I'm excited to return to coach HAT Summer Camp.

Tennis is my number one sport, I love to compete and I love to have fun. I strive to share my tennis experience in ways that makes this game simple and enjoyable. I have worked with players from different cultures and regions in Kenya, Uganda, Rwanda, Italy, Netherlands, India, Japan, and USA. This gives me a better understanding of different individuals which makes me flexible and allows me to deal with each individual effectively.

In 2009 I started off my coaching life with the little kids program at Sadili in Kenya. Since then I have engaged in coaching and I have had the opportunity to work with players at all ages. I have also worked
alongside coaches with higher experience from Zimbabwe, Tanzania, Burundi, Brazil, USA, and England.

Besides tennis, I have a passion for reggae. People call me Ladady, the true reggae daddy, and I enjoy promoting reggae culture.
