AubreyChesnutAubree Chesnut, MPAS, PA-C 

Aubree Chesnut received her cosmetics training from the most elite physicians in Southern California, including plastic surgeon Dr. Andrew Ordon of the TV show “The Doctors,” facial plastic surgeon Dr. Behroozan Torkian of the famous Lasky Clinic in Los Angeles, President of the American Academy of Dermatology and dermatologic surgeon Dr. Ron Moy in Beverly Hills, her husband Dr. Cameron Chesnut in cosmetic surgery while at UCLA, as well as numerous others.

This diversity of training is unmatched amongst the majority of injectors nationwide.  Aubree has a broad paradigm and breadth of knowledge to approach each patient's unique goals and needs - instead of forcing that patient into a narrow, dogmatic approach created by training with just a few perspectives.

Aubree was awarded her masters’ degree in Physician Assistant Studies from Western University of Health Sciences in Southern California. At Western University, she graduated at the top of her class on the Dean's List. Upon graduating, she completed a residency training program in Los Angeles, focusing exclusively on advanced cosmetic injection techniques where she honed her aesthetic eye.

While working in Santa Monica, Aubree practiced exclusively in aesthetic medicine. She is a highly sought after trainer for injectable fillers and neuromodulators, where she trains cosmetic physicians on the state of the art in modern aesthetics.

Aubree has an intimate knowledge of dermatology, facial anatomy, and an in-depth understanding of the aging process from the earliest changes of facial aestheics to advanced and dynamic tissue-aging concepts.  This combination of knowledge allows Aubree to pinpoint the most conservative, efficient, and natural approach to meet her patients' cosmetic goals.  This intimate understanding of the components of facial-aging also allows her to recognize each patient's unique needs, treating only necessary, sometimes subtle signs of aging to restore a natural, youthful appearance without looking artificial or overworked. 

Aubree caries a humble, friendly demeanor, under which lies leadership skills and an internal drive forged at the highest levels of athletic competition.  Aubree received her baccalaureate degree in kinesiology at Arizona State University, where she was captain of the women's basketball team, leading her team to the Elite 8 of the NCAA Basketball Tournament, and earning All Pacific 10 Conference honors in the process. She furthered those leadership skills while coaching basketball at North Idaho College and Seattle Pacific University.  

As a leader in the field of dermatology and aesthetics, Aubree has presented to dermatology physicians at the California Society of Dermatology and Dermatologic Surgery Annual Meeting, she is board certified by the National Commission for the Certification of Physician Assistants, and she is an active member of the American College of Phlebology and International Union of Phlebology. 

Aubree and her husband Cameron have returned home to Coeur d'Alene, Idaho. Together they enjoy surfing, snow skiing, waterskiing and spending time with their toddler son, Torin, and newborn daughter, Tatum.
