Seasoned government leaders with knowledge to share

Government Marketing University engages former government executives to share valuable insights from their perspective as public sector customers and decision-makersGMarkU believes the marketplace is most effective and responsive when vendors understand what government customers need and can articulate their value propositions in ways that resonate with government buyers. Our Ambassadors are former public sector executives who bring the “voice of government” and the viewpoints of government managers to GMarkU.  They are enthusiastic about educating others by sharing their experience, providing frank insights into the inner workings of government and passing along practical advice so vendors can better serve and educate government customers.

Kimberly Hancher

Former Chief Information Officer (CIO) at the US Equal Employment Opportunity Commission (EEOC) is now a consultant with Deep Water Point:

I joined the GMarkU Ambassador Program because it offered me a position of influence after retiring from the federal government as a member of the senior executive service (SES).  As a GMarkU Ambassador, I have been a keynote speaker, a radio talk show host, and a panelist at GMarkU events.  It has given me an entrée to interact with private sector marketing executives and other major players who do business with Federal, State, Local and Tribal governments.  I have a new found appreciation for the challenges faced by IT companies who offer software, hardware, services and solutions to government agencies.

Reasons to become a GMarkU Ambassador:

“Government Marketing University affords former Federal executives the opportunity to collaborate with public- and private-sector partners supporting the Spirit of “Open Government” principles. Serving as an Ambassador with GMarkU aligns with my Dots and Bridges mission to discover, cultivate and enhance relationships with thought leaders and change agents. I highly encourage my Government executive colleagues to consider serving as a GMarkU Ambassador, especially if you are considering a transition out of the Federal Government. The chance to learn from those that have walked this path is invaluable.”​
