Marta Gamboa is the Practice Administrator and Patient Coordinator for our office. She comes to Sierra Nevada Cosmetic and Laser Surgery with over thirty years of experience, across a number of specializations, within the medical field—from radiology to obstetrics/gynecology to facial plastic and reconstructive surgery. 

In her capacity as Practice Administrator, Marta attends to all aspects of office management—provider credentialing, health and welfare benefit plans, HR and personnel, office contracts, event coordination and communications, community outreach, and more—often wearing a number of hats at once. 

As Patient Coordinator, Marta works closely with Dr. Yamamoto, assisting in consultations with, and devising schedules for, patients who are considering surgery as a means to attaining the look and sense of well-being they have set their sights on. 

This dedication to expressing the unfamiliar in familiar terms reflects Marta’s wider-reaching motivation and purpose: she takes great pride and satisfaction in utilizing her accumulated knowledge and expertise to help patients effectively negotiate the intricacies of the medical and healthcare professions.
