IRS990/Desc0THE BRANDYWINE ZOO'S VISION IS TO INSPIRE AWE AND ACTION FOR WILDLIFE AND OUR EDUCATION DEPARTMENT'S PROGRAMMING IS CENTRAL TO THAT VISION. THE BOARD OF DIRECTOR IN THE SUMMER OF 2024 UPDATED OUR STRATEGIC PLAN WHICH HAD THE EFFECT OF REENERGIZING OUR VISION TO INSPIRE AWE AND ACTION FOR WILDLIFE. WE SAW OUR ON GROUNDS EDUCATIONAL PROGRAMMING CONTINUE TO GROW. OUR LITTLE NATURE EXPLORERS PROGRAMMING SOLD OUT AND THE CUSTOMER REVIEWS WERE OUTSTANDING. IN FACT, OUR OVERALL GUEST SATISFACTION SURVEY SCORES WERE SOME OF THE HIGHEST WE'VE REGISTERED IN THE 4 YEARS WE'VE BEEN TRACKING THEM. OUR BREW AT THE ZOO, SIP & STROLL "AFTER HOURS" EVENTS CONTINUE TO GENERATE SIGNIFICANT FUNDRAISING INCOME AND RECORDED THE HIGHEST ATTENDANCE TO DATE AS DID OUR MAJOR DAY-TIME SPECIAL EVENTS (BOO AT THE ZOO, SANTA AT THE ZOO, NOON YEAR'S EVE).
