East Elmhurst youngster Madison Gonzalez and tennis legend Serena Willams share an embrace at the end of an Elmcor youth group tennis clinic at the National Tennis Center on Thursday. Some of the 23 Elmcor youth group campers had never stepped foot on a tennis court before they traveled to the Billie Jean King National Tennis Center for a tennis clinic last Thursday. Serena Williams made sure their first time gripping a racket was a memory they will cherish forever.
