Who are we?

We are three people: a father-and-son team and a good friend.  Father (Marc Donner) is a semi-retired computer scientist who has spent his career in basic research, financial services, and high tech.  Son (Aaron Donner) is a professional chef.  Our good friend (Kathy Chan Bartmann), also a computer scientist, has collaborated with us on numerous projects.

Marc lives in NYC and summers in Southold.  Aaron lives in Southold year round.  Kathy lives in NYC and East Hampton.
