A New Chapter!

HESI is excited to launch a new chapter in our almost 30 year history. Although HESI has been an independently operated 501c3 nonprofit since 2001 – we maintained a charter agreement linking us to the 16 other ILSI branches. In Jan 2018, the HESI Board voted to conclude its charter agreement with ILSI. This move will allow us to more fully and efficiently leverage HESI’s growing scientific and operational strengths. We have also officially changed our name from the ILSI Health and Environmental Sciences Institute (ILSI HESI) to the Health and Environmental Sciences Institute (HESI). For more information, contact us at hesi@hesiglobal.org.
