Supplier Diversity

Danielle Dietz-LiVolsi - NuttZo Danielle Dietz-LiVolsi - NuttZo
NuttZo is a certified Woman-Owned Business with a strong commitment to social good. The owner and founder, San Diego-based Danielle Dietz-LiVolsi, combined her love for food with fitness and nutrition to create NuttZo's organic, non-GMO nut spreads. The genesis of NuttZo was created after adopting two vitamin deficient boys from the Ukraine that needed to be super boosted with high protein, healthy fats, vitamins, and minerals.

These spreads have become very popular in many of Costco's San Diego locations, and upon Costco's recommendation, NuttZo was named the 2015 Supplier of the Year for "Supplier Excellence" at the Council for Supplier Diversity – San Diego. In addition to this, Danielle and her husband are the founders of a 501(c)(3) charity called "Project Left Behind" which focuses on supporting orphanages throughout the world.
