Morris Animal Foundation’s President/CEO John Reddington Announces Retirement

Board of Trustees Names Tiffany Grunert Acting President/CEO

DENVER/January 30, 2018 – Morris Animal Foundation announced today that John Reddington, DVM, PhD, will retire from the organization in February. Tiffany Grunert, currently Vice President of Marketing and Operations, has been named Acting President/CEO while the Foundation’s Board of Trustees conducts a search to permanently fill the position.

“We greatly appreciate the impact that Dr. Reddington has had on the Foundation during his tenure,” said Walt George, Chair of the Morris Animal Foundation Board of Trustees. “We wish Dr. Reddington all the best in his well-deserved retirement, and look forward to having him in an advisory role during the upcoming transition.”

Since joining the Foundation in 2016, Dr. Reddington has overseen continued excellence in the organization’s core scientific programs, including expansion into new areas such as biometrics and data analysis, and significant enhancements to its communications, financial portfolio performance and fundraising efforts.

“I’ve always admired Morris Animal Foundation for the critical research they fund to improve and save the lives of animals around the world, and it’s been my privilege to be a part of that work,” said Dr. Reddington. “Looking to the future, the role of the Foundation will only continue to grow in importance as the animal health questions we seek to answer expand in number and complexity. Fortunately, there is a solid team in place here that is up to the task.”

The Board of Trustees has selected Tiffany Grunert to serve as Acting President/CEO while a search is underway. Grunert joined the Foundation in 2017, bringing to her role a rich set of experiences in the nonprofit and for-profit sectors.

“Morris Animal Foundation is at the forefront of advancing animal health, playing a crucial role in saving entire species through scientific discovery,” said Grunert. “During this transition, we’ll continue to focus on our highly respected scientific programs while ensuring the support systems for those programs stay focused and strong. I am grateful for the opportunity to continue this meaningful work with such an outstanding team.”

Grunert is a veteran to nonprofit animal causes and joined Morris Animal Foundation’s Leadership Team last year, leaving her position as Vice President of External Relations on the Executive Team of the Denver Zoological Foundation. Over her 13-year tenure at the Zoo, she was known to many in the Denver community as the Zoo’s spokesperson and known throughout the country as a communications and issues management strategist through her service with the Association of Zoos & Aquariums. 

Grunert led cross-functioning teams to open Denver Zoo’s signature $55 million elephant exhibit and worked with other cultural leaders to ensure the reauthorization of the Scientific Cultural Facilities District Tax before joining Morris Animal Foundation in March 2017.
