David Entin

David Entin

Founder & Director

David grew up in the Detroit suburbs and attended the University of Michigan, Ann Arbor, where he relished his college experience. He graduated in 1986, majoring in Psychology and French, and subsequently attended Cardozo Law School in New York City. After graduating and passing the bar exam, David relocated to Los Angeles.

Despite his law degree, David’s true passion lay in teaching, and he eventually taught English as a Second Language (ESL) to adults in both Los Angeles and Paris, and created business English courses for professionals.

In 1996, David returned to the U.S. from France and combined his passions for education and law by founding the American Institute for Legal Education. The Institute offered an eight-week summer program for foreign lawyers, held on the campuses of the University of Michigan and UCLA. For many years, the Institute hosted hundreds of foreign lawyers who learned about the American legal system while improving their English language skills.

Over the years, David spoke with countless U-M alumni who reminisced about their college days. Motivated by their enthusiasm for Ann Arbor and U-M, he created the Diag Days program, a weeklong event designed to bring alumni and other interested adults back to campus for an enjoyable and educational experience.

David returned to the Detroit area in 2020. When he’s not busy organizing the Diag Days program, he works as a substitute teacher in elementary schools, often with autistic children, which he finds especially fulfilling. He continues to inspire and engage others through his innovative programs and commitment to lifelong learning.
