William R. Sponholtz, III, M.S., PH.D.,
President and Founder
of Sponholtz Productions,

Dr. Sponholtz earned a PH.D. in organic synthetic chemistry with an emphasis in Natural Products Chemistry from Dartmouth College, a M.S. in organic synthetic chemistry from University of Tennessee, Knoxville, and a B.S. degree in chemistry from Pfeiffer College. In addition, Dr. Sponholtz has studied natural products chemistry and has done research at the University of Hawaii. Dr. Sponholtz teaches Introductory and Advanced Placement Chemistry, while offering several other independent studies courses ranging from screenwriting to multi-dimensional nuclear magnetic resonance. His research interests include the isolation and structural determination of bioactive secondary metabolites; i.e., drug discovery, which earned him the Massachusetts Chemistry Teacher of The Year Award from the American Institute of Chemists. Dr. Sponholtz and his students are working with indigenous healers and Shaman located in the Peruvian rain forest to isolate novel natural products that will have potential medicinal value. His afternoon research group, which meets every day after school for several hours, are exposed to various extraction techniques, chromatographic techniques (including flash, preparative, thin layer, and high pressure chromatography), and structure determination techniques as they hunt for novel, bioactive compounds. Dr. Sponholtz has authored various publications in scientific journals reporting novel, facile synthetic routes to previously unreported compounds with potential applications ranging from high-energy high-density explosives to medicinal compounds. In addition to his teaching and research interests, Dr. Sponholtz has coached soccer, skiing, and tennis at Cushing Academy.
