Quest Martial Arts Instructors Take Top Honors at New England Tang Soo Do Championships

THOMPSON, Conn. — June 10, 2026 — Quest Martial Arts is proud to announce that two of its senior instructors earned top honors at this year’s New England Tang Soo Do Championships, held in Westbrook, Connecticut and hosted by KJN Steve Voelker.

Ms. Erica Seraphin was named All-Around Cup Winner, earning the most combined points across sparring, weapons, and forms among all black belt divisions — a distinction recognizing the most complete competitor at the event.

Master Greg Martinez-Torres was named Grand Champion in all three divisions: Forms, Weapons, and Sparring, sweeping the top placement in each category.

“I am incredibly proud of these results. Erica and Greg are gifted coaches, but they inspire most by leading from the front — still training, still competing, and never asking of their students anything they aren’t willing to do themselves,” said Master Kristin Duethorn, owner of Quest Martial Arts.
