Joe Roberts, the University of Maine’s associate athletic director for external operations, has resigned after nearly 25 years at the university.

Roberts’ primary responsibility was marketing and promotion.

His last day was Friday.

“It has been a great run. It’s time to do something different. It seemed like a good time [to step down]. Twenty-five is a pretty round number,” said the 48-year-old Roberts, who grew up in Bowdoinham and attended Mt. Ararat High School in Topsham.

Roberts has worked in various capacities at the university.

He been involved in sports information, and he spent four years as the development director, which is a fundraising position.

His latest job paid him $75,803.42 per year as of April 8, 2014.

As for future employment, Roberts said he has some irons in the fire.

“We’ll see how it goes. I have experience as a fundraiser, and I hope to put that to work,” he said.

He said he has a healthy relationship with athletic director Karlton Creech and left of his own volition.

“Taking a look at how everything is done in athletics is nothing new. Individually, everyone is encouraged to take a look at what they do and how they can do things better,” said Roberts. “I had to take a look at whether I wanted to continue doing this or do something different.”

Creech said Roberts will be missed and that he was satisfied with his job performance.

“Joe’s a great guy. I enjoyed working with him,” said Creech. “He did a good job.

“It was his decision. Joe is looking at some new challenges, and I wish him all the best of luck.”

Creech said he isn’t sure whether he will fill Roberts’ position with a full-time hire or decide to go another route.

Roberts said he has a lot of positive memories from his time at Maine.

“I look back on it very fondly,” said Roberts, a 1989 graduate of the University of Massachusetts. “I’ve had the opportunity to work with a number of people. It has been a great experience.”

Roberts and his wife, Nancy, have two children, Cassie and Brent.

Cassie Roberts plays field hockey at Brewer High School, and Roberts said, “Now I’ll get to see more of her games.”
