“The leadership that Mark Holdt provided throughout the project was key to its ultimate success—the project simply would not have happened without Mark. His ability to develop the larger vision, rally support for it and see it through to completion is remarkable. I highly recommend Mark to any organization in need of his expertise and talents.”

“Special Transit has been the fortunate beneficiary of the services of Mark Holdt, Mountain Sage Consulting, for the past nine months. Mark is a rare individual who is both visionary in his grasp of the big picture and a master of the details. Time and time again, he amazed us with his insightful questions into our business, his thorough and in-depth analysis of options, and his crystal clear presentation of scenarios for our consideration and decision-making. Mark is an absolute pleasure to work with and I would not hesitate to engage him again in the future.”
Lenna Kottke, Executive Director, Special Transit, Boulder Colorado
“I am fortunate to have been on a non-profit board of directors that Mark Holdt has assisted through the mid to long range planning process. He was fully engaged, very knowledgeable and professional, and was able to help the board members realize that the process was not only of potential benefit, but could dramatically help their efforts and expand a program that was stagnant. I have dealt with many planning consultants for many different organizations, public and private, and would recommend Mark Holdt without reservation.”
Chuck Levine, Mayor Pro Tem, Estes Park Colorado
“I have brought Mark in to several client engagements to guide the process of board development, particularly where the board needed to implement a new governance model in order to become more effective. He is the best board development consultant I have every worked with in my 25 years of consulting experience. He not only creates a new model for boards but in doing so, he engages and energizes board members. They conclude the process with a whole new view of their role and new energy and passion for their mission.”
Carol E. Becker—Principal Owner of Sage Advice Consulting, Chicago, Illinois
“In my career with ExxonMobil Corporation, I held several positions with significant planning responsibilities, including being the chief planning officer for Exxon Corporation in the mid-1990’s. The caliber of Mark’s effort was equal to anything I experienced in my career with a very successful and well run corporation. He was particularly effective in leading the board and senior staff in the development of a planning process that is ongoing and renewing, rather than a planning document that is prepared and left of a shelf. He has been a pleasure to work with, and I can recommend him highly.”
Stephen F. Goldmann—Retired President and CEO of Exxon Asia
