CHESTERTON | Indiana Dunes National Lakeshore Superintendent Constantine "Costa" Dillon will leave his post in August, he announced in an e-mail late Tuesday.
"This August will make 35 years since I began my National Park Service career as a ranger at Independence National Historical Park," Dillon wrote. "I have decided that at reaching 35 years, it is time to move on to something else and I will retire from the National Park Service this August."
Dillon became superintendent at Indiana Dunes National Lakeshore in 2007, following Dale Enquist's retirement.
Dillon worked in more than a dozen parks in 10 states and had temporary assignments in 30 parks, he said. He has also represented the National Park Service in four other countries.
Dillon declined a request for an interview Wednesday about his retirement.
"I'd rather keep the focus on the park," he said.
In the e-mail announcing his retirement, Dillon continued those sentiments.
"There is a lot going on at Indiana Dunes National Lakeshore and many great things in the future of this park," Dillon said. "It will not be easy to leave, but it will be with the confidence that the excellent people who work here, and the people in the community who support the park, will continue to preserve and protect it for future generations."
