Vincentian to be inducted into US Coast Guard Academy Hall of Fame

Dr. James-Lyttle was a two-time All-American on the track, earning the honor during the indoor season in 1999 in the 100 meters before placing second in the 55 meters during the 2000 indoor season. She holds the school record in the 100 meters outdoors (12.22) and previously held Coast Guard Academy records in the 55, 100 and 200 meters.

Dr. James-Lyttle was the school record holder on two relays when she graduated, and was the 2000 New England 100-meter champion. She also won the Eastern College Athletic Conference (ECAC) Award for scholarship and athletic prowess.

“We were very lucky that such a talented student-athlete fell into our lap,” said Dr. Rose, the Head Track coach at the time. “She made an immediate impact in her first indoor track season. Jackie was born with great talent and, over her cadet athletic career, she cultivated that talent becoming a nationally-ranked sprinter.”

During her four-year collegiate athletic career, USCG said she won numerous track and field awards and honors.

She was awarded the Women’s Auxiliary Fleet Award for greatest impact on varsity athletics by a female cadet at the Coast Guard Academy; the Eastern College Athletic Conference Award for scholarship and athletic prowess; the United States Coast Guard Academy Coaches Award for outstanding contributions in women’s indoor track; and the United States Coast Guard Academy Athletic Association Monogram Award for outstanding participation in women’s outdoor track; in addition to earning the title of All American in Track and Field in both 1999 and 2000.

Dr. Rose said this list of awards is rarely collected by a single athlete.

In Venezuela, she participated in several projects with the cities to enhance the appearance and functionality of leftover spaces, looking to increase the life quality of the neighbors.
