About Me

Dr. Hoa Nguyen is a board-certified internist who is passionate in serving the sickest and frailest patients. With more than 12 years of experience in taking care of patients in multiple settings including in the ER, hospital, long term acute care, along with home bound geriatric patients, Dr. Nguyen knows how to make health care personal and improves healthcare with meaningful results. He also served as a regional lead physician at Landmark Health, the largest house-call program in the nation, managing complex, chronic patients at home.

In addition, with his previous position as a physician advisor and telemedicine provider for the State of California, he has learned how to meet and take care of patients whenever and wherever. He also specializes in treating patients to get off of opioid, alcohol, heroin, and other substance use disorders. He understands that most wellness goals are a process and are not solved with a prescription. He strongly believes in comprehensive principles of biochemical individuality based on genetic and environmental uniqueness, patient centered care as opposed to disease-centered care, health as a function of dynamic balance between internal and external factors, and health as a positive vitality rather than merely the absence of disease.
