She has been blessed to learn from many realms, from both the Western and Indigenous, the physical and spiritual. She has a double B.S. in Climate Sciences and Environmental Studies from Tufts University and an M.B.A. from UC Berkeley, but the most valuable knowledge she has learned has been from ʻ āina, kia ʻ i ʻ āina, and kahu ʻ āina. Her professional experience thus far spans social enterprises, entrepreneurship, technology, and impact investing, with experiences at Endeavor Global, Mana Up, Terner Housing Labs, Elemental Impact, and her own business Laua ʻ e Consulting.
