Dr. Dennis Clark holds a bachelor’s degree in Biological Sciences from Sacramento State College and a Ph.D. in Botany, specializing in plant chemistry, from the University of Texas at Austin. He spent his entire 30-year professional career in teaching and research at Arizona State University. He has also been Visiting Professor at the University of California and at the University of Heidelberg in Germany. He is currently an adjunct professor at the Southwest College of Naturopathic Medicine.
Dr. Clark is a leading expert on plant natural products chemistry and integrative medicine, an award-winning teacher, and co-author of a best-selling college textbook on botany. He has been awarded grants for his research from the National Science Foundation, the U.S. Department of Agriculture, and the Alexander von Humboldt Foundation. His studies have been published in dozens of national and international scientific journals. He has lectured at international conferences in the U.S., Canada, Mexico, Germany, Belgium, and England.
Dr. Clark’s journey into medical botany and natural health began when, as a young university professor, he found that his knowledge of plant chemistry could be used to explain how plant natural products affect human health. This led to his discovering which botanicals were best for enhancing the health of his family and friends. He soon found that his university students also wanted the same kind of information. Their ever growing demand for his science-based approach to natural health led to several new classes in integrative medicine, medical botany, and natural products pharmacology.
As Dr. Clark states, “I feel blessed to have a background that enables me to evaluate both the scientific literature and the popular press on natural medicines and to dig out, understand, and explain to the public how and why these medicines work. People should be able to get straightforward answers to simple questions about which natural medicines will work for them and what commercial brands are reliable for what they need. Unfortunately, these answers are not easy to find for people who do not have an extensive scientific background. My role is to provide this service, to bring the best research available on medicinal plants to the public’s attention and to lead the way in the evaluation and development of quality products.”
Over the years Dr. Clark has gathered the best information available on natural approaches for preventing and overcoming many human disorders. These include herpes, obesity and overweight, menopause and hormone imbalance, cancer, osteoporosis, arthritis, stress, cardiovascular disease, diabetes, digestive problems, candida (yeast) overgrowth, and many others. He uses his expertise from many years of teaching, researching, and writing to provide the public his clear, powerful, and often entertaining views of a research scientist about being healthy naturally.
Dr. Clark currently co-owns, with his wife Eve, Doctors Nutrition Center and Weight Management Clinic in Tempe, Arizona. He is in demand as a guest speaker for local groups and radio and TV programs on many aspects of wellness.
