Mr. Yoshii has a long history of volunteering and giving back to the community.  While in college, he volunteered for vari-ous charity organizations helping distribute food and Christmas gifts during the holidays. For over 10 consecutive years during the early 2000’s, Mr. Yoshii and his family would travel every Christmas break to the Rancho Santa Marta Or-phanage outside of San Vicente, Baja California, Mexico.  He would spend a week each year helping with various con-struction projects, including helping to survey out areas of the orphanage as someone had donated a transit level to the orphanage, but no one there knew how to use it.  He also volunteered as a cook and timer at many swimming and diving competitions in southern California for well over 10 years starting in the early 2000’s through mid-2010’s.
