About Us


Troy J. Andreasen M.D

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.

Dr. Andreasen was then chosen as one of the first medical school graduates in the United States to train in an integrated General Surgery /Plastic Surgery program that emphasized cosmetic and reconstructive surgery. At Loma Linda University, Dr. Andreasen excelled in all facets of his training and established himself as one of their premier plastic surgical trainees. His specific interests included cosmetic surgery of the body and face and reconstructive surgery of the breast.

Dr. Andreasen has been actively involved in missionary service since he was 19 years old. He currently captains the Loma Linda Good Samaritan Plastic Surgery efforts in Cabo san Lucas, Mexico. Twice yearly, this team offers reconstructive surgery services to impoverished children who would otherwise have no access to these procedures. Dr. Andreasen's training in cleft lip and palate repair as well as his experience in burn surgery are valuable components of the missionary endeavor.

Dr. Andreasen's pursuit of excellence in Plastic Surgery continues now in his private practice. With personalized service and care, he treats every patient individually and provides complete surgical care from the initial consultation through the recovery. Emphasizing safety, Dr. Andreasen performs his cosmetic and reconstructive procedures at several hospitals and surgery centers throughout the Inland Empire.

Patient Testimonials

    "Thanks again for your flexibility"

    Dr. Andreasen & Staff,

    Thank you so very much for your patience and cooperation with my bank and payment issues. I'm so grateful that I did not have to reschedule my surgery. Thanks again for your flexibility.


    Thank you for changing my life

    Dear Dr. Andreasen & Staff at Arrowhead,

    I wanted to thank you all for everything you have done. My reasons for plastic surgery weren't for enhancement (although that is a nice bonus), it was to correct a deformity that has inhibited me my entire life. You all treated me with dignity and kindess and were sensitive to my situation. I felt very comfortable and confident with Dr. Andreasen that you understood my expectations and you more than exceeded them. I am so pleased with my results and I know that everything is just going to keep getting even better with time. I will always recommend you to everyone. Thank you for changing my life.

    Warmest thanks
