Our Story

Mark Hyman, Ph.D.


Mark Hyman, Ph.D. is the founder of Stainless Process Systems (SPS). He oversees the engineering, strategic development, and sales operations of the company.


Before he founded SPS in 2007, Mark was the founder and president of Alliance Finishing and Manufacturing, a company that specializes in electroplating and engineering services for aerospace, military and commercial component manufacturers. He leads both companies today, relying on his 30+ years of experience in the manufacturing and electroplating industries.


From our home in Oxnard, CA, the heart of Ventura County's industrial & technology corridor, SPS supports our customers' long-term precision equipment fabrication needs, as well as the manufacturing and repair services they require on-site at their facility. 

Mark works directly with customers to provide a high level of support and requirements comprehension while focusing on a solution-oriented approach throughout the engineering, fabrication and delivery process. This has led SPS to become the market leader in California for pressure vessel manufacturing and on-site engineering solutions.


Mark received his Bachelor of Science in Chemical Engineering from University of California, Los Angeles (UCLA), a Masters of Science in Chemical Engineering from Illinois Institute of Technology (IIT) and a Ph.D. in Materials and Mechanical Engineering from University of California, Santa Barbara (UCSB).
