Members mention the coaches by name in their reviews for a reason. At O-SEA, coaching is hands-on, experienced, and genuinely invested in your progress.
Joshua Miller, known to everyone as Josh, owns and leads O-SEA CrossFit. He is a CrossFit Level 3 Trainer, one of the highest coaching standards in the sport, and a lifelong competitor: in 2025 he finished 22nd in the Men's 50-54 division at the CrossFit Games, and he has been competing in CrossFit since 2012.
Before the gym, Josh spent fifteen years in restaurants: serving, bartending, and managing. He coaches from the same place. Figure out what someone needs, then help them get better.
That blend of elite experience and genuine warmth is exactly what members describe in their reviews. As one put it, Josh and the entire gym were super friendly and made it a fantastic experience. He coaches the way he competes: with real skill, and real heart.
For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come.1 Timothy 4:8
