I founded Diamond Consultants, LLC in 2016 with a vision of empowering leaders to reach their full potential. Now, in 2025, I am fully dedicating my time and focus to this purpose, helping emerging and established leaders achieve success and avoid the common pitfalls of leadership.

After decades of success in program planning, nonprofit management, research and evaluation, philanthropy, and the federal government, I realized that my impact could be exponentially greater by supporting others in similar roles. While my formal coaching and consulting expertise is extensive, the most valuable asset I bring to our work together is the hard-earned wisdom I’ve gained from my own experiences across diverse professional industries.
