Who We Are
Guided by a vision of positive change.
At the Stiles Nicholson Foundation, we believe that true progress begins with people. That’s why we invest in education that equips students with the tools to succeed, in innovation that sparks new possibilities, and in community initiatives that lift others and create shared opportunity. Guided by a vision of positive change, we are committed to preparing the next generation, empowering today’s leaders, and inspiring stronger, more resilient communities for years to come.
Established in honor of great men.
The Stiles-Nicholson Foundation was formed in 1992 as a private family foundation in memory of William John Stiles (a WW II fallen soldier), and William Nicholson (a German POW survivor), the father and step-father of David John Stiles Nicholson.
