Dennis grew up on an apple farm in northeastern Ohio. He holds an MA in teaching English as a second language from the School for International Training and a doctorate in community college education from George Mason University. His teaching experiences range from elementary schools to universities, as well as adult basic education. He speaks Spanish and has lived and worked in Costa Rica, Mexico, and Colombia.

From 2000 until he retired in 2020, he led Prince George’s Community College at University Town Center, an off-campus center serving more than two thousand students each semester.
