Denison’s water tower makes a bold statement: “It’s A Wonderful Life.” Playing off the title of the 1946 holiday film classic that stars Denison Native Donna Reed, the community uses this slogan to reflect Denison’s spirit.

Nestled in the hills surrounding the Boyer River, Denison is home to a diverse population of more than 8,000* residents. Denison’s school district reports that more than 20 languages are spoken in the homes of their more than 2,000 students. That spirit of diversity shines throughout Denison in business, community, education, and recreation. We invite you to visit and see why our diversity makes life in Denison uniquely wonderful.
