About John

John (a.k.a. “Dags”) has been a gym-rat his entire life, participating competitively in everything from basketball to marathons and ultramarathons, to innertube water polo. John first started CrossFit in 2009 in order to complement his running training, but was quickly drawn to the myriad dimensions of fitness that CrossFit training afforded beyond mere speed. To that effect, Dags is committed to CrossFit New Haven athletes’ skill development, across the entire spectrum from novices to competitive athletes, basic footwork to advanced power and endurance development, and helping enhance each of our athletes’ strength and conditioning knowledge and ability.
