The GreenMark Team

Steven Bloembergen, Ph.D.

Steven-BloembergenSteven Bloembergen, Ph.D.
Founder, Chairman and CEO

Dr. Steven Bloembergen founded GreenMark Biomedical in Michigan in 2016, with a vision to deliver health based benefits to society through biobased targeting technologies. GreenMark’s mission is to “Enable dentists to preserve teeth through early diagnosis and treatment”. Steven has 30 years of leadership experience in the development and commercialization of biomaterials. He started a company called EcoSynthetix (ECO) in Lansing, Michigan in 1996, now a global corporation. In January 2011 ECO opened its state-of-the-art Center of Innovation facility in Burlington, Ontario where it pursues the development of biobased products for industrial applications. He and his team helped prove out the technology with pilot lines and production sites in the US and Europe, building a manufacturing capacity for starch nanoparticles in excess of 200 million lbs/yr. The company held its IPO in August 2011 (TSX: ECO) and was Canada’s largest IPO in the Cleantech sector. In 2012, Steven received the Ernst and Young “2012 Entrepreneur of the Year Award”. He developed a broad global IP portfolio and established a network of university collaborators. These collaborations using ECO’s starch nanoparticles for dental and medical applications resulted in the foundational technology for GreenMark. Steven is the inventor of over 25 patent families related to biomaterials. He received his Ph.D. in Polymer Science and Engineering from the University of Waterloo, Ontario.
