Two founding partners of The Leonardo have stepped down from the arts and science museum's board of directors to bring "fresh voices" to the project, said Mary Tull, the museum's executive director.

Joe Andrade, executive director of the Utah Science Center, and Leslie Kelen, executive director of the Center for Documentary Arts, give way to three new members of the board: Allen D. Roberts, Will West and Adam Price.

"These new board members represent more than new faces in our organization," Tull said. "They illustrate the active steps The Leonardo is taking to bring critical expertise and fresh voices into this exciting project."

Roberts is president of Copper Roberts Simonson Associates, a 65-member architectural firm headquartered in Salt Lake City. He will serve as the Center for Documentary Arts' representative on The Leonardo board.

West will represent the Utah Science Center on the board. He currently serves as the CEO and co-founder of Control4, a manufacturer of home automation systems.

Rounding out the new board members is Price, an attorney with Jones Waldo Holbrook & McDonough.

"We deeply value the rich experience and new perspectives they will add and look forward to more exciting changes in the year to come," Tull said.

The Leonardo will be a hands-on art, culture and science center inspired by Leonardo da Vinci's multidisciplinary approach to exploring the world. The museum is expected to open in early to mid-2009.
