Our Name
Radiance is about light. We help you shed light on the lessons and impacts of your work so you can learn, plan, and communicate better. And Radiance is about connection. We bring people together and use radiant thinking to see patterns and themes, and to help you connect your board, donors, staff, and community members to the vision you have for your work.
Radiance (formerly Korwin Consulting) reflects our evolving identity while building on the strengths of our past.
