The River Hill All-American, a three-time, first-team All-Metro selection and a four-year starter who led his team to three straight state championships and a 67-7 record, had narrowed his choices to Brown or Yale.
"The academics are great at either place, but Brown has a great social atmosphere plus a good soccer program," Crew said.
He has a 4.0 GPA and a 1300 SAT. He has scored 56 career goals and has 41 career assists.
Brown's soccer team was ranked No. 17 nationally and lost to Virginia in the third round of the NCAA playoffs last season.
Crew will be part of a program called PLME in which he would be automatically accepted into Brown's medical school.
"It would be an eight-year program and is partly why I chose Brown," he said. "But I haven't decided whether I'll do that or pursue a degree in economics."
Both his parents attended Brown, and his sister, Alika, currently attends Brown.
Crew, 6-foot-1, 165 pounds, has played three years in the Olympic Development Program and is a member of the under-18 national pool.
River Hill coach Bill Stara said: "He has some of his best years ahead of him. He's still growing. His quickness is deceiving. He's long-legged and covers a lot of ground."
