Ellenborough Table Tennis Club celebrated a double at the English Schools Individual Table Tennis Championships in Doncaster.
Amelia Chan, 11, was crowned English Primary Schools Girls Champion and Denise Payet, 12, retained her Under-13 title.
Walker Primary School pupil Chan beat Molly Hancock - the reigning English National Champion - in the quarter-finals, beating English number one Katie Holt in the semi-final.
English number two Danielle Kelly was dispatched in the final, with Chan dropping only two sets against opponents who represented England in the British Primary Schools' International three weeks earlier.
Number one seed Payet, a pupil at Enfield County School, beat Sussex's Kate Cheer in straight sets and will now compete for the English Schools Team at the Home Countries International Event in the Isle of Man next month.
Payet has also been selected by the English Table Tennis Association to play in the Spanish Open in Platja d'Aro, Girona from May 7-11 and will also represent England in the Cadet Six Nations at the end of the month.
Reflecting on the young duo's success, Ellenborough TTC chairman Keith Williams, said: "Denise is setting the standard for other girls in the area to aspire to and everyone at the club, and Walker Primary School, are delighted with Amelia’s first national title.
"Both girls benefit from the professional coaching they receive from Gergely Urban and Tibi Kadar at the club, but by winning through the whole competition day without coaches in their corner, the girls demonstrated exactly what we instil in all our athletes: self-confidence, self-reliance, a keen tactical awareness and strong mental resilience.
"I’m optimistic that if Amelia increases the number of hours she practices an opportunity will soon arise for her to train with the England Youth Development Squad," added Williams.
