otherworld Jiu Jitsu

otherworld Jiu Jitsu in Lawrence Township was founded by Shane McCarthy and Collin Wiemer with the goal of making high-level Brazilian Jiu-Jitsu accessible to students of all backgrounds and ages. Shane brings over a decade of BJJ experience as a black belt under Art Keintz, while Collin holds a BJJ black belt under Nick Salles and Daniel Maira and a judo black belt under Olympian Colton Brown. Their combined backgrounds reflect a commitment to technical precision and practical martial arts education, rooted in both traditional Brazilian Jiu-Jitsu and Olympic-level judo. Classes at otherworld cover the full scope of modern grappling, including structured fundamentals, gi and no-gi training, and open sparring for adults. Collin’s judo expertise adds a strong stand-up element to the curriculum, while Shane’s coaching style emphasizes clear, hands-on instruction and attention to detail. The academy offers a dedicated kids program for ages 7–13, with both gi and no-gi classes that focus on building confidence, discipline, and body awareness. Adults benefit from a steady progression through fundamentals, live positional training, and open mat sessions, with the schedule alternating gi and no-gi formats throughout the year. The school’s approach is practical and inclusive, welcoming families to train together and encouraging students to find their own path within the art. Drop-ins are permitted, and visitors can expect a direct, technical atmosphere where progress is measured on the mats. The blend of BJJ and high-level judo lineage gives the academy a technical depth uncommon in the area, supporting students whether their goals are self-defense, fitness, or competition.
