Zimny is a former Harvard professor who ran the education consultancy group IvyAdmit Consulting LLC.
The Boston Globe reports that the Chows say they gave $2.2 million to Zimny, who said he had contacts at Harvard and would funnel donations from the Chows to elite colleges.
They charge Zimny with fraud and breach of contract. They want their money back.
Zimny denied the allegations in court papers.
