Time Tested 
Three Tomatoes Catering celebrates 35 years.
In 1977, Joanne Katz, Peggy Beck, and Dede Winterburn formed Three Tomatoes Catering on a whim. Since then, the company has changed personnel (Winterburn bowed out after a few months), grown in stature (it’s now the official caterer of the Museum of Contemporary Art Denver), and branched out from staples like chili con queso (one of the appetizers served at the trio’s first bash). These days, the caterer is regularly tapped for bold-name events such as dinners for Michelle Obama or fund-raisers for Mitt Romney, but Katz equally enjoys the smaller events. “I love being part of the once-in-a-lifetime experiences like weddings,” Katz says. “We get to provide the food, which is always celebratory.”
