Areas of Expertise

Strategic Planning, Board Development, Management Consulting

Sandi was excellent with whom to work. When we explained our expectations and background on our organization, she carefully listened and developed a workshop which addressed our needs. She even changed her personal travel plans to accommodate our time frame. I highly recommend Sandi and Capacity Partners.

Get to know me

Sandi has hiked over 1,200 miles of the Appalachian Trail and she and her husband, Chris “Trailboss” Brunton, oversee three miles of the AT in northern Virginia. Sandi and Chris live in the historic town of Harpers Ferry, WV, where they can walk out their back door and be on the Trail in just a few minutes. Their 166-year-old home has graffiti in the attic from when Union soldiers were billeted in the house. Cat Sweetie Pie often chases ghosts through the rooms.
