ABOUT WMA
Waterman's Martial Arts (WMA) opened its Oneida/Sherrill location on Feb 2, 2008, and our second location in Hamilton on July 10, 2018. As an affiliate of the Zen-Do Kai International Association, we devote most of our energy to self-defense training with a focus on prevention. The dojo has been fortunate to develop contacts with police officers, military, and other real-life experts who have guided our practice beyond the scope of traditional martial arts. All programs allow for modification based on the individual’s abilities.

but in rising every time we fall.”

Meet Our Instructors
Sensei Heath Waterman
3rd Degree Blackbelt
Heath began training at Pinney’s American Karate in 1993 and earned his black belt in 1999 at age 13. He was the first to achieve this rank in the school and one of the youngest to be certified by the Zen-Do Kai International Association.
Despite WMA students routinely scoring high in tournaments and tests, Heath continues to increase his knowledge and discover ways to improve the school and its programs.

Jeanine first joined the dojo as a parent, watching her daughters climb through the ranks. In 2014, she was invited to train under Sensei Woodcock and immediately connected with the sword arts.
