She attended Parkland High School in South Whitehall Township, Pennsylvania, where she starred in productions of Bye Bye Birdie and The Crucible. She graduated from Parkland High School in 1996.
Following her graduation from Parkland High School, Conlin moved to New York City to study acting and was accepted into New York University's Tisch School of the Arts. While working toward her B.F.A. in Theater, she appeared in several productions at the Atlantic Theater Company and the Playwrights Horizons Theater School, and traveled to Amsterdam to study with the Experimental Theatre Wing's International Training Program.
Following her graduation from NYU, Conlin was chosen to be a part of the cable documentary series The It Factor, which focused on the lives of young actors in New York City.
