At 20, Dean represented the United States at the late September,
1988 Summer Olympics in Seoul, South Korea, where he competed in the B Final of the
men's 200-meter butterfly event, and finished with the ninth-best time overall of 2:00.26, an exceptional swim, but somewhat below his prior hopes. The American team did not have their best overall performance that year. Following the olympics, he met adversity, recovering from a collapsed lung in 1989 and a more severe collapsed lung in 1990 that required surgery.
Post-swimming careers After ending his swimming career, he attended
Saint Louis University School of Law beginning around 1992, where he served as the school's NCAA Compliance Officer. After graduating law school in 1995, Dean practiced law in
St. Louis, where in 1996, he served as an Assistant Attorney General in Jefferson City, Missouri. Dean married Mary Helen Flanagan on October 12, 1996 at the College Church at St. Louis University. Flanagan was a 1991 graduate of the University of Illinois in Champaign, and like Dean, a 1995 graduate of the St. Louis University School of Law, where the couple met. After law school, she initially served as a Public Defender in Jefferson City. Mark Dean has recently lived in
Chesterfield, Missouri with his wife Mary, with whom he had a son and daughter. ==See also==
