Content and Exhibit Developer

Sherry is an exhibit developer and writer. She has over 20 years of experience crafting stories and designing experiences in children's museums, national parks, zoos, gardens, and cultural and natural history museums. The power and beauty of a well-told story are always her goals.

Since joining EDX in 2007, Sherry has worked collaboratively with clients to develop and design exhibits that inspire visitors. She leads workshops, manages project schedules, shepherds design from concepts through construction, and writes exhibits, too!

One of her favorite parts about working at EDX is exploring nature. That can mean paddling across Lake Union to the office with co-workers or canoeing the Rio Grande scanning for javelinas!
