They'll tour hospitals, spend time in classrooms and hear lectures from medical researchers and practitioners.
Doctors at Jefferson Memorial Hospital, where her mother works in the lab, donated money to help pay the $1,630 tuition for the July 12-22 program.
Reid, who has a 3.5 grade point average, said she wants to become a physical therapist or medical doctor.
"It depends on what kind of doctor, though," Reid said. "I'm not into all of the blood."
Reid, who also is a member of the Jefferson High marketing club, is going to Denver on April 24 for the club's national competition. The local group earned the trip by winning a state contest.
She is also a member of the student government, the National Honor Society and the peer mediation program.
She also works as a cashier at Martin's supermarket in Charles Town.
But it's her sports experience that has led her to consider a career in medicine.
"I'm always getting hurt, breaking a bone or spraining something," Reid said, laughing.
As a ninth-grader at Charles Town Junior High, she was playing in the county basketball championship semifinals when she hurt her left wrist.
Her mother wanted her to go to the hospital, but the team won the game and Reid said she did not want to miss the championship.
"I told her I'd always regret it if I missed it," Reid said.
She played the game and even blocked a shot with her left arm. After receiving the championship trophy, she went to the hospital and learned she had broken several bones in her wrist.
She wore a cast for months, she said.
