Our Medical Director, Roger Schechter has reinvented himself three times in his career. He started as a Family Practice doctor, but was quickly enticed by the fast paced world of Emergency Medicine. Eventually, he evolved in to a thought leader in Chronic Wound Care.

Dr. Nina Chaya was elected to the Tri-City Healthcare District Board in 2020, where she has been dedicated to optimizing patient care and advocating for safety and wellness. A Physician Anesthesiologist at Tri-City Medical Center (TCMC) since 2013, she has held leadership roles, including Chairperson of the Anesthesiology Department and the Blood Utilization Committee. On the Board of Directors, she helped secure funding for the Emergency Room remodel, oversaw the construction of the Psychiatric Health Facility, managed the hospital's COVID response, and participated in the search for a healthcare partner.

Beyond medicine, Dr. Chaya is deeply involved in philanthropy, volunteering with Mercy Outreach Surgical Team and organizations like Champions for Health and the San Diego Humane Society. She has participated in pediatric surgical missions in Mexico and led fundraising efforts for Tri-City Medical Center, including chairing the 2021 gala and raising funds for life-saving equipment.

A San Diego native and daughter of Lebanese immigrants, Dr. Chaya discovered her passion for medicine after undergoing spine fusion surgery as a teenager. She earned her pre-med degree from UC San Diego, attended medical school at New York Medical College, and completed her Anesthesia training in New York.
