John Gieseman

Principal and Founder

Mr. Gieseman started his career at Honeywell UOP’s Riverside pilot plant facility just outside of Chicago. It was there, that he, like thousands of other recently-graduated chemical engineers, learned process engineering including catalysis, reaction kinetics and the importance of steady state operations and material balances.

Mr. Gieseman spent ten years in engineering and technical service with UOP advising on dozens of startups and troubleshooting assignments throughout the world. He had long term project assignments in Japan, South Korea, Saudi Arabia and Canada. He also had the opportunity to design process units that are operating today in Slovakia and the Ukraine. 


During this time, he also troubleshot and managed capital projects at UOP’s commercial catalyst manufacturing facilities in the United States, England and the Netherlands. Mr. Gieseman also took a year assignment to work on a small team that chose and installed UOP’s first ERP system. 

In 1999, Mr. Gieseman moved to Lummus Technology’s Bloomfield NJ office and started as a sales manager and helped put together the successful Chevron Lummus Global joint venture. Following this, he moved to Houston and formed the Lummus Refining Business Group where he licensed many process units and oversaw Lummus’ research and development and production (engineering) groups in the refining area. During this time, Mr. Gieseman negotiated (and renegotiated) numerous agreements with Lummus’ catalyst and technology partners.   

In 2008, Mr. Gieseman moved back home to Chicago and worked as a group manager at Jacobs Consultancy. There, he executed and led many studies and projects related to improving the operations of process industry clients. He also helped develop the business strategies for mid-size private firms. Mr. Gieseman led and assisted on a number of due diligence projects for varied clients throughout the world. Mr. Gieseman recently spent eighteen months learning about the detailed engineering business working as the Director of Process Industries for a local engineering contractor.

Mr. Gieseman has written and presented over a dozen technical papers for various industry journals and conferences. He graduated from the University of Notre Dame with a B.S. in Chemical Engineering and received an MBA with concentrations in Finance, Marketing and International Business from Northwestern University.  

Riverside Process Engineering and Consulting is supported through a strong network of consultants with specialties to match current assignments, when necessary.
