Three blocks from the Pacific Ocean at 4965 Cass St, 92109, PB Fitness is a veteran-owned, independently operated gym built from the ground up by co-founders Katie Cardoza and Justin Verdugo. After two years of searching for the right building—meeting with the SBA, banks, lawyers, and financial advisors along the way—the pair secured the Cass Street lease and opened what they describe as a mom-and-pop gym with no franchise backing, no angel investors, and entirely organic growth. The facility stands out for its three separate rooftop training decks and a 1,000-square-foot indoor functional training studio with floor-to-ceiling mirrors, oversized ceiling fans, and a large garage door that opens for ocean air circulation. PB Fitness also hosts wellness fairs and local community events that connect health-minded Pacific Beach residents, and Slowly Restaurant and Lounge nearby draws the post-class crowd for weekend brunch. The penthouse-level deck offers 360-degree views of San Diego, with turf, functional training gear, free weights, and cardio equipment facing the water—a setting Google reviewers describe as unmatched for sunrise and sunset workouts. Daily group classes rotate through full-body conditioning, glute and back circuits, chest and tricep combinations, shoulder and leg days, and a Friday "choose your own adventure" format, all led by experienced trainers on the open-air north deck. The ground-level studio includes a StairMaster, treadmill, Concept2 rower, spin bikes, cable machines, dumbbells, TRX, and a range of functional equipment available during open gym hours. Members heading south on Cass after their session sometimes stop at Firehouse American Eatery & Lounge on Garnet for hearty portions and craft cocktails. A 4.8-star Google rating across 48 reviews reflects the personal touch Cardoza and Verdugo bring to daily operations, with multiple reviewers mentioning the gym's resident cat as a beloved fixture. Open gym memberships run month to month, and the Peerspace listing makes the studio available for private events, photo shoots, and group bookings.
