"After nearly 50 years in the business, it is time for me to step aside from the day-to-day operations and let progress continue," said Patrick Adams. "It has been a long, rewarding career and I am very thankful for all we have accomplished."

Patrick began with MKS Pipe and Valve Co. in 1971 and led the company through its most significant history of growth and evolution.

Steven Adams takes the helm as president and CEO after 10 years with MKS, serving in a variety of roles including business development manager and executive vice president. Prior to joining MKS, Steven served in roles at Enterprise Fleet Management and GE Capital.

"I am thrilled to step in and continue the legacy established by Patrick and the entire team at MKS," said Steven. "This is a company built largely on the premise that teamwork is the key to success. It is my plan to continue to lead in the manner established by Patrick, leaning heavily on the strength of our team."
