Dr. Tim Marshall is a neuropharmacologist and nutritional biochemist with over 25 years of experience in functional medicine.  Since 2012, he has been working closely with neurologist, Dr. Carol Henricks at NorthStar Neurology and Hyperbarics (in Tucson, AZ) to tailor nutrient and detox protocols that enhance the healing benefits of hyperbaric oxygen therapy (HBOT).  In addition to his work as a holistic neurospecialist, he also serves as the Chief Science Officer of FoodPharma, a leading-edge, dietary supplement, contract/manufacturing company in Los Angeles.  


He completed his doctoral training in Neuropharmacology from the University of Arizona, College of Medicine, and has a Bachelor's in Biochemistry and a Master's in Organic Chemistry.  Following his Master's, he entered the realm of drug discovery research as an analytical chemist for Pfizer Global Research and Development in La Jolla, CA and Aventis-Selectide Pharmaceuticals in Oro Valley, AZ.  After a few years in Big Pharma, he returned to academia to teach (2002-2004) and later complete his doctorate in Medical Pharmacology (2008) – specializing in Neuropharmacology, and minoring in Medicinal Chemistry and Toxicology.  


For over 3 decades, Dr. Marshall has taught seminars and college/university classes in chemistry, biochemistry, and pharmacology.  His passion for root-cause healing solutions began as a child fueled by his quest to identify the root causes of his own health issues, and passion to understand health challenges at their most basic level has driven him throughout his life.  He enjoys being out in nature every chance he can get, exercising, playing sports, yoga, and deeply cherishes his time with family and friends.
