Raised on North shore of Oahu, was fortunate to see north shore's wild wild west days. He fished, surfed, dove, and hunted. Leif was introduced to jiu jitsu in 1996 on the north shore at the old rec center across from foodland, which is now torn down. Leif moved to California where he trained over there for a year and came back home to Oahu and trained at James Labrador house with all the boys, kai garcia, kala alexander, makua rothman, and Rico Jimenez just to name a few. Leif made a dojo under his house with Kai Garcia. Since they hunted, together they called it the "boars nest." Boars Nest were the first real dojo on the north shore side of the island with wall mats, cages, and bags. From A through Z they have had an elite crew of martial artists walk through those doors to train, in which they taught moves, in return the North Shore crew pushed them in to waves .
