The FC Dallas CEO has been on administrative leave due to a domestic dispute at a New York hotel.
Quinn has been on administrative leave since November when allegations of a domestic dispute in a New York hotel ended with him being arrested.
“After much consideration, I have decided to resign from FC Dallas to spend more time with my two beautiful daughters,” Quinn said in a statement released by the club. “I will be forever grateful to Clark and the Hunt family for giving me an opportunity to lead this great franchise, and I sincerely appreciate the hard work and dedication shown every day by the FC Dallas family.”
According to the team statement Dallas will begin its search for a new president immediately, with Dan Hunt, vice president of Hunt Sports Group, continuing his "leadership" role with the club.
