American Martial Arts Academy began in 1992 as a family-owned-and-operated business, and a second studio opened in Placentia in 2012. The founder, Shihan Brad Wenneberg, is a retired police officer, and the co-founder is his wife, Bonnie Wenneberg. Sensei Jason leads the flagship dojo, and Senseis Nikhil and Megan Joshi lead the Placentia dojo. Instructors are full-time staff, and most instructors started with American Martial Arts Academy as children. The program describes its mission as providing character-driven instruction that helps children and adults thrive, with a family-centered focus and a positive, fun, and caring environment. The American Martial Arts Academy was celebrated as one of the best martial arts studios in the country and describes its teachers as top-tier, with extraordinary instructors providing a stable continuum of instruction. The program states that it supports the local community.
American Martial Arts Academy offers a Little Ninjas program for ages 3–5, Kids Martial Arts Programs for ages 6–12, a Summer Camp for ages 5 and up, and an After School Program for all ages. The summer camp is described as a Karate Summer Camp that happens all summer long and includes karate classes, field trips, creative activities, and weekly park days. The program environment is described in testimonials as clean and well-kept, with flexible class schedules for busy families.
Parents in testimonials describe the staff as warm, inviting, friendly, and excellent with all age groups, and note that instructors keep classes fun, upbeat, and energetic. One parent, a child psychologist, reports appreciating the inclusiveness and respectful attitude toward different learning styles and describes the flexibility in attending classes as helpful as a busy parent. Other parents describe American Martial Arts Academy as one of the best activities their child has been involved in, and as a place their children adore and want to continue attending. A parent testimonial also describes American Martial Arts Academy as a “home away from home,” with a balance of indoor fun activities, local field trips, weekly park days, karate instruction, and a community of families.
