Since the Partnership for Public Service’s founding in 2001, we understood that establishing an organization to revitalize our government service was no small undertaking. But we knew it was vital to the health, security and prosperity of our nation.

Over the past 15 years, across Republican and Democratic administrations, we have leveraged our nonpartisan, nonprofit status to help make our government—the most important and complex organization in the world—more efficient and more effective for the American people.

Thanks to the support of our sponsors and donors, and close collaboration with our partners and federal leaders and agencies across government, we’ve accomplished a lot in our first 15 years. This #GivingTuesday, we’re celebrating the successes of our organization through a social media campaign using the hashtag “#Partnership15”.

This involves looking back at milestones from each of our years of operation. From establishing the Best Places to Work in the Federal Government rankings in 2003 to taking over hosting responsibilities for Public Service Recognition Week in 2006 to establishing our Center for Presidential Transition earlier this year, we’ll focus on a different year of operation each day leading up to November 29.

One of our flagship programs, the Samuel J. Heyman Service to America Medals, celebrated its 15th anniversary this year. This program, known as the “Oscars” of government service, highlight excellence in our federal workforce and inspire other talented and dedicated individuals to go into public service.

Mia Beers, winner of the 2015 National Security and International Affairs medal, is a great example of how everyday federal employees make a difference both in America and around the world. Beers led a team of U.S. responders who risked their own health to coordinate personnel from five federal agencies and helped turn the tide on the Ebola crisis in West Africa.

“When I left, I told my 3 year old that ‘Mommy’s going to help people,’” Beers told us. “When disaster strikes, Americans help.”

Stories like these remind us of the passion that public servants have for our country and encourage us to continue our work to bring about effective government for the American people.

#GivingTuesday is the perfect time to reflect upon all that we’ve accomplished in our short history and to capitalize on our momentum to ensure even greater progress in the years ahead.
