Our Core Values

Our core values are the written expression of the values that guide us in everything we do.

Our logo represents the diversity of Wallace Group and how our team works together with our surroundings in simple yet rich harmony. As one team comprised of multiple disciplines and perspectives, we find unity not only in our core values, but also in the elements of earth and water. This connection and the multi-disciplinary nature of our company inspired our logo as our company identity changed in 2004 from John L. Wallace Associates to Wallace Group. Our logo demonstrates an abstract of the earth, water, and layers of specialties exemplified by our team. The brilliant, deep red color was influenced by the richness of the earth’s soil.
