A 3-time United States champion (2002, 2004, 2007), he won the 2002 IAAF World Cup tile and finished fourth in the Olympic finals in 2000 and 2004.

Born in Baltimore, Maryland, Carter grew up competing in track & field on the age group level.

At the age of 12 he was diagnosed with a rare neuromuscular disease called Myasthenia Gravis which left him unable to run, walk and sometimes chew his food.

He soon had surgery to have a tumor removed from his chest and was able to return to the sport of track and field.

He has helped numerous athletes become national All-Americans on the age group, high school and collegiate level.
