For 11 years, the West Hartford resident was senior deputy editor of Bristol-based espn.com, and before that was executive producer for "The Dan Patrick Show" for ESPN Radio and senior editor of ESPN The Magazine. He also has worked at People, Esquire, Harper's Bazaar and New York Magazine.
Twain House Executive Director Cindy Lovell said Hassan was chosen from among more than 100 applicants.
"We were immediately impressed with John's knowledge and experience and how he can bring them to bear as we expand our global visibility," Lovell said in a statement. "With our 150th anniversary just a few years off and our increased efforts in tourism outreach, John's expertise will ensure we reach the widest audience possible."
Hassan was born in Holyoke, Mass., and graduated from Bates College in Maine in 1982. He begins his new duties on June 20.
"In addition to increasing visitors to Mark Twain's Hartford home, we also plan to continue a lively schedule of readings, lectures, and performances that will help to preserve and extend the legacy of the father of American literature," Hassan said in a released statement.
