Kylie Tanabe, Physician Assistant

Kylie TanabeKylie Tanabe is a Physician Assistant at Cedars-Sinai Medical Network, in the Beverly Hills Hands Surgery Department. She works closely with Dr. David Kulber both in clinic and in the operating room.

At a young age, Kylie was certain about her purpose. She completed a 5-year BS/MS Physician Assistant program at Wagner College in Staten Island, New York. While completing her rotations in NYC, she also helped plan medical missions for her PA program to Belize and worked in the NHS in England to provide psychiatric assessments in underserved communities across the UK.

After graduation, Kylie knew that surgery would be the natural next step for her. She entered the Norwalk/Yale Surgical Residency Program for PA’s, where she would then combine her love and passion for surgery and traveling. She decided to live in one of the last remote places of the world, Papua New Guinea for several months to help the trauma, surgery and fast track service of the medical mission station.

Kylie found a true love and joy in the medical mission lifestyle, however was also drawn to the Beverly Hills Hand Surgery Group at Cedars-Sinai due to their contemporary way of thinking, innovation of new surgical techniques and continuous research. During her time with the practice, she became one of the founders of the Nonprofit Organization called Ohana One, where they bring surgical care and education to areas that need it most, all over the world.

When Kylie is not seeing patients, in the operating room or working on Ohana One’s development, she can be found hiking and camping around Southern California where she lives.
