It was the first time since 2015 that TGS had been represented in the Under-14, Under-16 and Under-19 age groups.
Both the Under-14s and Under-16 were crowned county champions, with the Under-19s coming second in their section.
It was a long and challenging day, with 21 rounds being played and all three competitions went down to the final round of matches.
Julie Cross, the TGS coach, said: “I am immensely proud of all the students. They showed how important teamwork is and how hard work and commitment to training pays off.
“Thank you to all the parents who turned out in significant numbers to support the players and staff. Your encouragement was greatly appreciated and contributed in no small part to the success of all the teams.”
