About Premier IFM
Premier IFM is an integrative functional medicine center founded by Dr. Craig Mortensen, an IFM-certified practitioner (IFMCP) with over 12 years of exclusive functional medicine practice and more than 5,000 clients served worldwide. The clinic takes a root-cause approach to chronic disease, combining advanced lab testing, detailed health histories, and systems-based analysis to create personalized treatment protocols. The practice specializes in complex chronic conditions including autoimmune diseases, thyroid dysfunction, chronic fatigue, digestive disorders, hormonal imbalances, CIRS, Lyme disease, and metabolic issues. Beyond consultations, Premier IFM offers in-office therapies such as hyperbaric oxygen therapy (HBOT), infrared sauna, cold laser therapy, and halo salt and red light therapy at their Placentia, CA location. Dr. Mortensen holds certifications from the Institute for Functional Medicine, Functional Medicine University, and has trained under Dr. Datis Kharrazian. The team includes Nurse Jessica Cardona and Kristen Mortensen. The practice does not bill insurance directly but provides superbills for out-of-network reimbursement, and offers wholesale lab pricing for uninsured patients. With a 4.8-star rating across review platforms, patients consistently highlight the thoroughness of the evaluation process, the evidence-based approach, and successful outcomes for conditions that conventional medicine failed to resolve. The clinic serves both in-person and telemedicine patients nationally and internationally.
