maria Costello

Executive Director

Maria has been the Executive Director of the Paper Discovery Center since May 2016. Prior to this she lived in Milwaukee and was the director of two art museums. She finds working with nonprofits fulfilling and uses more of her skills and talents than her for-profit positions ever allowed.

Besides travel (often to visit grandkids!), she enjoys good books, live theater, movies and interior design.

She feels honored to be part of such a wonderful and talented team at the Paper Discovery Center.

michael breza

Lead Educator

Michael fell into museum work by good fortune, learning his craft on the job. For over 28 years he has created exhibits that make people happy. He loves exhibit work; it makes him think and explore new directions. He does not know where his talent comes from, but he is grateful for it.

One of the most interesting aspects of museum work for Michael is his work with some unusual items: He has stood in a treasure vault filled with shipwreck coins, driven Abraham Lincoln’s shawl to a museum, smelled perfume from the Titanic, held a Viking sword, hung artwork of dazzling skill, and put the Wicked Witch of the West hat on display.
