Coronado Karate is a martial arts dojo at 1005 C Avenue in the Crown Shops, operating under the instruction of owner David Adams — a fourth-degree black belt, Coronado native, and Coronado High School class of 2004 graduate who started training at this same location at age seven. The studio has operated continuously since 1989, first as Martial Arts America under Sensei Miko Peled (sixth-degree black belt) and then under Adams, who purchased the school in October 2012 after training under Peled for nearly two decades. Classes run for children starting at age four, teens, and adults across karate and Taekwondo curricula that progress through belt ranks toward black belt testing, with the program emphasizing discipline, self-defense, and leadership development at every level. The C Avenue location sits in the same fitness and recreation corridor as Coronado Tennis Center and several Coronado gym studios, placing it within the island's densest cluster of movement-based training options. The 92118 dojo has hosted community food drives and partners with Coronado schools on youth development programs, reflecting Adams's roots in a family that has lived on Coronado Island for multiple generations. The belt system progresses students from white through black, and the teaching model requires advanced students to assist lower belts one-on-one before leading portions of group classes — building instructional skills alongside technical proficiency. Athletes cross-training in martial arts often supplement their conditioning with mobility and injury-prevention work, and One Life Physical Therapy in Coronado handles the joint and soft-tissue rehabilitation that supports sustained martial arts training. The 1005 C Avenue address is at the corner of 10th and C Avenue, three blocks north of Hotel Del Coronado and two blocks east of Orange Avenue. Adams logs approximately 60 hours per week at the dojo and continues his own training while pursuing a business degree through Penn State University's online program.
