Mark Thompson

Chief Executive Officer, The New York Times Company


"Brimstone brought great creativity and open mindedness to bear in their engagement with The New York Times.  They guided us to bold and challenging conclusions but did so in a way which worked with, rather than against, the grain of our culture as an organization.  It was an energizing and enjoyable process which really helped us accelerate change in the company."

George A. Scangos, Ph.D.

Chief Executive Officer, Biogen


"I value my partnership with Brimstone. Their experience at developing and aligning executive teams is really helping us find new approaches to leadership as the scale and complexity of our business grows. It’s valuable to have advisors who aren’t afraid to speak truth to power. Even more importantly, they have helped us improve our ability to be candid with one another. It’s that kind of candor which is a foundation of performance."

Mary Dillon

Chief Executive Officer, Ulta Beauty


"Brimstone has been a valuable partner for me and for the organizations I've led. Brimstone is extremely effective at helping executive teams develop and align to accelerate business performance. In my role as chief executive, their trusted counsel has helped me to hone my leadership instincts and more quickly drive results."

“Transforming the culture of a global organization is incredibly hard work.  Brimstone partnered effectively with our leadership team, helping us develop and then execute a plan for change.  Their counsel was practical and processes effective, helping us shave months if not years off our effort to transform the culture of Global Finance.”

President, Sales and Product Operations, Motorola Solutions

"I chose to work with Brimstone because they think about consulting differently. The big strategy firms bring all sorts of analysis, but we already know most of what they have to tell us, because we are experts in our own business. Brimstone doesn’t try to solve our problems for us–that’s our responsibility. Brimstone helps us to solve our problems for ourselves, as effectively and quickly as possible."

Kenneth DiPietro

Executive Vice President, Human Resources. Biogen


"Brimstone has been a great thought partner to me about leadership and change. They have a very effective way of bringing their expertise to bear without taking over or giving us an answer. It’s our responsibility to lead change at Biogen—they are valuable guides in helping us drive the process in a way that fits our unique business, culture, and circumstances."

Jeff Childs

Chief Human Resource Officer, Ulta Beauty


"The people at Brimstone have been trusted partners of mine for two decades. Regardless of whether we’re actively engaged in a project together, I turn to them for counsel and perspective, helping me think things through. And over the years I’ve repeatedly worked with Brimstone when bringing together new executive teams—they are incredibly effective at accelerating and improving a senior team’s ability to develop, align, and perform."

Guido Gianasso

Former VP, Human Capital of IATA


"Since 2003, IATA has transformed from a sluggish bureaucracy into a quick, innovative and results-oriented organization. Brimstone has served as our guide and counsel throughout the process."

Tim Wentworth

Chief Executive Officer and President, Express Scripts

Medco Health Solutions

"Brimstone was my secret weapon when I had to take an organization, which was used to having a few leaders at the top drive all strategy and thinking, and get 50 or so folks understanding that they have to be the leaders. I would not have achieved half of what I did without Brimstone's help."

Michael J. Long

Chief Executive Officer, Arrow Electronics, Inc.


"Brimstone's processes have enabled us to turn complex challenges into manageable, actionable, measureable work. And along the way, we've become a more aligned organization with a common understanding of our vision, values and strategies."

David P. Steiner

"Brimstone has been a terrific partner–to me, my Senior Leadership Team and the entire organization–in our pursuit of alignment and growth. They helped us get on the same page, maintain focus, and work together toward bottom-line results."
