Tennis Instructor TJ Underwood

T.J. began his tennis career as an Assistant Coach/Instructor at Thorbeckes in 2005.  After 3 years, he became the Director of the Thorbeckes Tennis Program as well as a Certified Teaching Professional of the United States Professional Tennis Association (USPTA). He loves the challenge of connecting with every single student he works with to find unique/specific ways to get the absolute best out of them. “There’s no better feeling than seeing someone you’ve coached have their hard work pay off,” T.J. said.

He also loves to see the players use tennis to gain confidence and become more outgoing off the court as their tennis skills improve – something that T.J. experienced himself. Ask any of his students (which range from 7 to over 70 years) and they will tell you he has an unparalleled commitment to help them succeed and have made a huge impact on their lives. This is why T.J. finds that all of the friendships he has built with the students over the years is his most meaningful accomplishment of his career.
