Teri Matsukawa


Teri Matsukawa serves as the Finance Adviser to the Hawaiʻi Agricultural Foundation.  Teri’s role is a natural extension of her consulting practice and professional background working with Not for Profit clients as CPA with Big Four accounting firm KPMG.  Growing up on Kauaʻi, Teri’s dad had a chicken farm and grew anthuriums as “a half business, half hobby.”  She enjoyed helping her dad in the garden, where they harvested local favorites like guava and lilikoi and staples such as corn, sweet potato and green onions which she admits she didn’t always appreciate as a child but does now as an adult.  Teri loves being part of the team promoting the HAF mission in the community.
