Change is the new normal.

Bob Weiler and Bob Marcus founded Brimstone in 2001 with a shared belief that a business’s ongoing success depends on its ability to change—to adapt to new market realities, out-maneuver its competition, and develop strong leaders. The idea of transformation is embedded in our name (brimstone is another name for sulfur, which early alchemists used as a catalyst). It is also core to our mission of empowering organizations and their leaders to drive enduring change.

The roots of Brimstone tap into two different sources for inspiration. One is Outward Bound, where Bob Weiler served as EVP of the Hurricane Island Outward Bound School, the largest Outward Bound School in North America. The other is the University of Michigan’s Ross School of Business where Bob served as director of the acclaimed Global Leadership Program, working closely with leadership expert Noel Tichy to build a cutting-edge executive development initiative. Years studying, leading, and consulting to world-class companies led to the creation of a firm that uses change to deliver breakthrough results, develop leaders, and align organizations.

Today, Weiler leads the Brimstone team of over 30 senior-level consultants. From our headquarters in Camden, Maine, Brimstone has deployed team members around the globe to help some of the world’s most highly regarded companies across a variety of industries. Marcus left Brimstone in 2017 for other endeavors, but will always be part of the tribe.
