Cultural Advisor: 
Tom Brennon

Tom has been a mo’o for the Protect Kaho’olawe Ohana since in 1990,  after the State of Hawai‘i designated the island as a natural and cultural reserve, “to be used exclusively for the preservation and practice of all rights customarily and traditionally exercised by Native Hawaiians for cultural, spiritual, and subsistence purposes.” Hawaiian protocol for Keau’ohana has been performed based on Jaya’s personal training with Tom since the late 1990’s. As a retired kumu of HAAS charter school, his supportive presence to HER becomes more prominent.
