David Haase, MD is a doctor, teacher, entrepreneur, and innovator who is deeply committed to maximizing wellness for everyone. Dr. Haase received his medical training at Vanderbilt University and completed his residency in Family Medicine at Mayo Clinic in Rochester, Minnesota.

He is board certified in Family Medicine and Integrative Holistic Medicine. Early in clinical practice, Dr. Haase realized that something very important was missing. He went to medical school so he could better understand and address the root causes of illness and dysfunction – and thereby facilitate the creation of health for individual patients. Instead, he found his training was largely limited to naming disease (putting the patient into a “box”), blaming disease (the context had nothing to do with the problem), and taming disease (often with powerful drugs not tailored to the unique genetics of the individual). To fill the void he sought out additional medical training and certifications in nutrition, integrative and holistic medicine, functional medicine, health coaching, neurofeedback, systems biology, genomics, bioinformatics, and precision medicine. By identifying and treating the unique root causes of their conditions, Dr. Haase saw remarkable improvements in his patients’ health.

Dr. Haase treats a wide range of conditions and has special expertise in fatigue, brain-related disorders (mood, attention, anxiety, insomnia, Alzheimer’s, Parkinson’s, seizures, head injury), inflammatory and immune dysregulation, allergy, and cancer support. His friendly manner, enthusiasm, and humor make learning fun and light the way for a patient’s healing journey.

Dr. Haase is the Founder and CEO of MaxWell Clinic, which was established in 2003. Dr. Haase is the co-founder of MDOmics, a company that analyzes complex data sets to enable more precise clinical care, and a non-profit organization that helps youths make healthier choices for their bodies and their communities ( He is the Chief Medical and Innovation Director for XYMOGEN, a leading professional nutraceutical company as well as Chief Medical Officer for TrendShift, which specializes in personal risk factor monitoring, health trend tracking, and health-care cost reduction for large employers.

Dr. Haase serves as medical advisor to Evoke Neuroscience, a company that delivers technologies that promote brain health, and Metabolon, which develops metabolomics diagnostics for precision medicine.

Dr. Haase is a sought-after lecturer and teaches internationally about the root causes of disease and innovative, safe treatments through his faculty position at the Institute for Functional Medicine and as an adjunct professor at the University of South Florida, University of Miami, and Western State University. Dr. Haase integrates nutrition, metabolomics, neuroelectrophysiology, genomics, environmental factors, and lifestyle medicine to help his patients get better and he shares these concepts with other medical professionals for improved patient care.

Dr. Haase is passionate about making better health accessible to all people and uses his innovation and creativity to bring new diagnostics and treatments to the medical field for the betterment of medicine and health.
