Inside this safe, judgement-free zone, a team of bilingual caretakers and educators work with students from 18 months to 15 years old inside a newly-installed dance studio. Though students are taught in groups, caretakers pledge to give each one plenty of individual attention. Acknowledging that many parents have demanding schedules, the center welcomes drop-in care as well as early drop--offs and late pickups.

  • Rock City Climbing
    Shawn Crawford has been climbing for more than 40 years, working with wilderness search and rescue at age 13 and later serving as a park ranger. Today, he’s the owner and head instructor at Rock City Climbing, where he puts his American Mountaineering and Guiding Association certification to use as he teaches climbers of all experience levels techniques of top-rope climbing, belaying, rappelling, and bouldering. Inside a gym equipped with more than 10,000 feet of climbing walls, as well as top-rope and bouldering areas, students learn basic and advanced climbing techniques in a range of classes. As they climb, instructors introduce techniques such as hand and foot placement and what to do if gravity starts working in reverse. Visitors can leave the main floor to explore a tunnel maze behind the climbing walls, filled with trap doors, narrow passageways, and drops of up to 11 feet. When not overseeing his gym, Shawn leads outdoor climbing excursions to challenging locales such as Joshua Tree, Riverside Quarry, and the Statue of Liberty. He also oversees a nearby ropes course, where staffers help groups and individuals navigate two ziplines, as well as more than 20 aerial challenges at heights of up to 60 feet.

  • Go2Karate
    After beginning martial arts in 1980, two karate students earned seventh-degree black belts and eventually went on to become masters and open their own schools. They wanted to share their love of karate and other martial arts with even more people, so in 2011, they created Go2Karate.com. Go2Karate is a website that connects people around the world with martial arts schools in their communities. It also helps users learn about the various styles of martial arts?teaching them the differences between karate, Brazilian jujitsu, capoeira, and mixed martial arts, for instance?as well as helps them find a class based on their individual goals. On the easy-to-use website, parents can find a karate school to successfully teach their child self-confidence and respect. Kids' karate classes acquaint students with others their own age, and also build skills that help them deal with schoolyard bullies. For women, karate and other martial arts do double duty as a fun and confidence-building fitness regime while also equipping them with essential self-defense moves. Karate and martial-arts classes for men help them not only hone fighting technique, but also reduce stress and drop pounds while chiseling stronger bodies. Users simply enter their location information and the style of martial arts they're interested in, and the website shows them a bounty of schools conveniently located nearby, many with a class schedule and news about recent events.
