Laura Gold has been a practicing clinical pharmacist for over 20 years. A graduate from St. John’s University School of Pharmacy in Queens, NY and with an undergraduate education in compounding and natural medicine, Laura has served as a clinical pharmacist in various capacities within the pharmaceutical industry. After realizing the need for a balanced approach between natural and allopathic medicine, she founded and operated her own compounding and nutritional pharmacy in Peoria, AZ, developing into a complete wellness center housing multiple integrative practitioners. During this time, she advanced her training as a compounding pharmacist through the Professional Compounding Centers of America, and most recently became a Certified Diplomate of the American Board of Anti-Aging Health Practitioners.

At FMC, Laura supports the clinical team in caring for members’ pharmacological needs and serves as the patient’s advocate. Her mission is to educate and empower patients to feel great and look amazing by promoting this model: “let your food be your medicine, your kitchen be your pharmacy, and your lifestyle be your doctor.”
