Founded in 1988, the Association incorporated in 1989. It was among the first public school Alumni Associations in the United States.
Over the years it has provided formation assistance to many other Alumni Associations in the St. Louis area.
The Ladue High School Alumni Association is a 501(c)3 tax exempt organization supporting the school through donations, scholarships and gifts that have totaled over $50,000 since inception from voluntary member dues of $15 annually.
The Association and its programs are funded entirely by voluntary donations from its members.
It receives no support from the School District or the High School itself.
