Yes. Dr. Antoine holds dual board certification, fellowship status with the American College of Emergency Physicians, board certification through the American Board of Integrative Medicine, and the Institute for Functional Medicine Certified Practitioner designation. These credentials span emergency medicine, integrative medicine, and functional medicine.

Dr. Antoine built her clinical foundation in nationally recognized Emergency Departments before co-founding CFFH in 2011. She brings more than 26 years of medical experience to her practice. Her own recovery from lupus through integrative medicine shaped her focus on root-cause care for chronic illness.

Dr. Antoine uses the proprietary five-step Fully Functional method to build each patient's treatment plan. She looks for the underlying drivers of disease rather than treating symptoms in isolation. She also works alongside a patient's existing primary care physician rather than replacing that relationship.
