Although he became a fan of the Green Bay Packers, the long and cold winters were a bit too much for this good natured Brazilian, so he moved to California in 2021. He initially worked with the Santa Clara County, mostly working at a Ryan White HIV/AIDS Program and at the second busiest Tuberculosis clinic in CA. This further strengthened his knowledge base in these areas. He found his ideal practice setting in Newport Beach with us, starting in February 2022 and is fast becoming known for his strong knowledge, dedication, work ethics and bedside manners.
