Engineers Country Club is proud to offer 5 Har-Tru tennis courts. Har-Tru is the world’s leading clay court surface, made from billion-year-old Pre-Cambrian metabasalt found in the Blue Ridge Mountains of Virginia. It is a natural green stone that is extremely hard and angular — two very important qualities when it comes to tennis court construction. We offer a variety of programs for you and your whole family, ranging from lessons to tournaments. Tour our facilities to learn more about our tennis programs.
