COLORADO SPRINGS, COLO. - The United States Olympic Committee Board of Directors has elected Marty Mankamyer as USOC President. Mankamyer, who was nominated for the office late last month by the USOC Executive Committee, will serve as the organization's top volunteer leader through the remaining two-plus years of the current quadrennium, including the 2004 Olympic Games in Athens, Greece. Mankamyer replaces Sandra Baldwin, who resigned the USOC presidency on May 24, 2002.     "I am honored to have been chosen for this office by my USOC peers," Mankamyer said. "When I first became involved in youth soccer activities in which my children participated, I never imagined that one day I would be elected to serve as president of the United States' most prestigious sports organization. Now it is my charge to continue that volunteer work on behalf of all of our nation's athletes, and our National Governing Bodies and member organizations. We have a lot of work to do on the road to Athens in 2004 and beyond, and I am anxious to begin."    A realtor in Colorado Springs, Colo., home of the United States Olympic Committee, Mankamyer has been a member of the USOC Board of Directors since 1990, where she previously represented the U.S. Soccer Federation, and, as Vice Chair of the NGB Council, served on the USOC Executive Committee from 1992 to 1996. In December 2000, Mankamyer was elected as USOC Secretary, an office subsequently re-designated Vice President Secretariat. Since Baldwin's resignation, Mankamyer has acted as the organization's President as legislated in the USOC's Constitution.    The first woman elected to U.S. Soccer Federation's Executive Committee, Mankamyer led the successful effort to include women's soccer on the official program for the 1996 Olympic Games in Atlanta. In addition to serving as Assistant Chef de Mission for the U.S. Delegation at the 2000 Olympic Games in Sydney, Mankamyer was soccer delegation supervisor at the 1996 Olympic Games, water skiing supervisor and soccer liaison at the 1995 Pan American Games in Argentina, and soccer's volunteer at the 1983, 1979 and 1978 National Sports Festivals.     A native of Farmington, N.M., Mankamyer and her husband, Jack, have four daughters, three sons and
