In 1986 William "Sonny" Ching established Halau Na Mamo O Pu'uanahulu which is currently located in the Kapahulu and Kapalama areas of Honolulu.

I was preordained that I would be the one to continue hula in my family. Both my grandmother and great grandmother could foresee it. After I was born, my great grandmother said I was going to be a chanter. At the age of four my grandmother started teaching me some of the chants and we would progress to the dancing. When I was twelve, my father decided that I shouldn't dance so my grandmother taught me without his permission. Now he is my biggest supporter.

My grandmother Lena Pua'ainahau Eleakala Nahulu Guerrero was my confidant, my roommate, and my best friend. She taught me on a one-to-one situation and we usually did things on a daily basis. We always preceded our training with a prayer and because my grandmother was of pure koko and was fluent in the language, she prayed in Hawaiian. That's how I run my class today. Before we dance, we pray to Akua and to Laka. My grandmother told me I can never set up a kuahu because my halau is to be dedicated to God. But it was all right to do the chants that honor Laka because those chants need to continue otherwise it would be forgotten. For us this is part of the ritual that prepares us spiritually, physically, and mentally for the hula. This is one of the ways we build our mana.
