As an experienced tribal leader committed to Native American interests and the mission of economic growth, Treppa is often called upon to testify at legislative hearings for a variety of issues impacting Indian Country.

Congressman Mike Thompson (CA-4) named Treppa Lake County’s 2023 Woman of the Year recognizing her contributions not only to her Tribe but to the county and surrounding community.

In 2019 Treppa and her Tribe co-produced “Saving the Sacred” a short documentary nominated for an Emmy on development of a Memorandum of Agreement (MOA) with other local Sovereign Tribal Governments and the County of Lake for protection of sacred sites and artifacts. This work earned the California State Governor’s Historic Preservation Award in 2016.

Prior to her role with the Tribe, Treppa worked in private industry for 18 years. She was born in Lake County and graduated with a Bachelor of Science from the University of San Francisco. Treppa’s ongoing efforts have contributed to the process of restoring the Tribe’s land base. She has spearheaded funding negotiations and refinancing for the Tribe’s current gaming ventures. She played a vital role in overseeing the construction of the Tribe’s Casino and represented the Tribe in raising capital, structuring and development of the Tribe’s e-commerce and biofuel  businesses.
