Clark takes over the Green Terror tennis program this season.
Clark played collegiate tennis at Morehouse College, where he was a four-time All-American. He served as team captain for three seasons and won back-to-back regional championships.
In 1992, he won the NCAA National Rolex Small College championship.
"I'm excited to take on this opportunity," Clark said. "Passion and hard work are two qualities that I thrive on and will bring that to this position. This is one of those moments in life where you look in the mirror and ask, 'Who will I become?' I have a personal dedication to enhance the lives of the student-athletes at McDaniel."
He previously spent the 2005 season as an assistant tennis coach at nearby McDonogh School.
Clark has served as the senior pastor of Omega Baptist Church in Owings Mills since founding the church in June 2003.
Clark graduated from Morehouse with a bachelor of arts in religion in 1994 and earned his master of divinity from Howard in 1996.
