Our Firm

Decades ahead of their time — and still leading.

Founded in 1981 by Donald Schiller and Joseph DuCanto, Schiller DuCanto & Fleck LLP pioneered the application of complex business litigation principles to family law at a time when no one else was thinking that way.

Today, our 38 attorneys handle the most complex, high-stakes matrimonial matters in the country — including multi-million dollar asset divisions, business valuations, custody disputes, and novel legal issues that create new law.
