Last night, Yi Eubanks was recognized by the City of Chino Hills with the “Unsung Hero” Award, presented by Council Member Art Bennett.
This honor celebrates Yi’s years of dedication to the special needs community, both through her work as an educator in Chino Hills and through her longtime service on the Anthesis Board of Directors.
Please join us in celebrating Yi and thanking her for the compassion, commitment, and leadership she continues to bring to our community. ❤️
