Bert has done many projects working with other artists. These projects are particularly exciting becasuse neither participant could make the work without the input of the other.

This window was commissioned for the Miles Memorial Hospital, Damariscotta Maine. Albinus Elskus designed it, cut the glass, and kiln fired the painting. Bert was honored with the responsibility to lead it and install it. Albinus Elskus is one of the most important glass painters and designers of the 20th century. He is also notable for teaching his craft to many lucky students including Bert.
