Originally from Salt Lake City, Utah, Dr. Troy J. Andreasen grew up interested in plastic surgery. As a successful amateur boxer, he became acquainted with a plastic surgeon while in that sport. Through this association, his interest in the broad field blossomed and he went on to immerse himself in its study for the next several years.

Following two years of religious missionary service, Dr. Andreasen completed medical school at the University of Utah. While there, he developed advanced microsurgical skills under the direction of the renowned hand surgeon, Graham Lister. His efforts in microsurgical research helped define the effects of trauma on microcirculation. Dr. Andreasen was awarded the highest achievement award from his alma mater and graduated at the top of his medical school class.
