Mixed martial arts academy at 504 Nautilus St, La Jolla, CA 92037, between Draper Avenue and La Jolla Blvd. Founded by Noad Lahat, a veteran of both the UFC and Bellator and a 3rd-degree black belt in both Judo and Brazilian Jiu-Jitsu, SD Fight Academy offers classes in MMA, kickboxing, BJJ, wrestling, and self-defense for all ages and skill levels — and the Nautilus Street address places it across from La Jolla High School, whose student athletes train here. Beginner programs cover striking, grappling, and submissions; advanced adult classes include sparring, fight strategy, and intense drilling. Private one-on-one sessions are available. Shares the Nautilus Street block with Twin Dragons Kenpo Karate at 506 Nautilus, creating a two-gym martial arts corridor steps from the Bird Rock neighborhood.
