About
Dr. Lauren Fitzgerald trained originally as an anesthesiologist before pivoting to functional medicine. Her own health challenges led her to explore what conventional medicine had not resolved for her. What she found reshaped her entire approach to patient care.
Today, Dr. Fitzgerald serves as Owner and Medical Director of Larimar Med. She merges her foundation in Western medicine with evidence-based alternative therapies to prevent, heal, and reverse disease. Her clinical work spans functional medicine, preventive medicine, BHRT, weight loss, neurotoxin injections, and advanced body contouring. She sees patients in person in St. Charles and treats patients across all 50 states via virtual visits. Dr. Fitzgerald moved to St. Charles in 2020 and opened Larimar Med after months of renovation, naming the practice after a turquoise crystal known as the tranquility stone.
