Meet The Team
STEWART GRAHAM
Chief Executive Officer
Stewart Graham has over 20 years of experience in the lithium-ion industry. He began his career by introducing lithium iron phosphate (LFP) cathode technology to the world, commercializing LFP in the United States. He then brought LFP to China by building the first LFP factories there.
Stewart has remained active in the lithium-ion battery space, developing cells and packs while building battery factories around the world. With many partners and friends in the industry, he is able to leverage those relationships to provide the best batteries in the world to his customers.
He holds a B.S. degree in Chemical Engineering from Brigham Young University.
JOE TURNER
Chief Technology Officer
Joe Turner has been in the lithium-ion battery industry since 2002. He came from the semiconductor industry and joined Valence Technologies to refine the production parameters of lithium iron phosphate (LFP). As LFP production moved to China, Joe began working on other phosphate-based materials.
Later, he joined K2 Energy, where he oversaw the ramp-up of the company’s first LFP cell manufacturing line. His primary responsibilities at K2 included materials, cell design, and production, as well as designing, building, and commissioning new factories. Joe was also involved in DOE/DOD grants and worked on sizing and troubleshooting battery packs, modules, and systems.
After 11 years with K2 Energy, he joined an external R&D lab, Coulometrics, which provided full cells, testing, and analysis—typically in the 18650 format—running 10–15 cell builds per month for over five years.
BRYAN BLAKLEY
Chief Operating Officer
Bryan is a natural strategist and proven leader, known for staying on point. With a successful background in venture capital and executive roles at Fortune 200 companies, he has led high-performing organizations across multiple industries.
He has spent several years in the energy industry, where he has helped deploy enough self-generated energy to replace two fossil fuel plants and power tens of thousands of homes. Bryan’s passion for process and technology has driven his leadership in building information channels, solutions-based software, and systems architecture.
Today, he ensures that Grand Teton Energy Solutions delivers top-quality products efficiently and on time to its customers.
