Founded in 1961 by John Bertucci, Jim Mills, and Barrie Sales, MKS is currently led by President and CEO Dr. John T.C. Lee, an MIT-educated chemical engineer with a deep pedigree from Applied Materials and Bell Labs. The executive team includes EVP and CFO Ramakumar Mayampurath, who joined in late 2024 from Rogers Corporation, and EVP and COO James A. Schreiner, who recently returned to operations after spearheading the integration of the Atotech division. Technical leadership is distributed across divisional CTOs, including Aaron Radomski (Power Solutions) and Gordon Hill (Plasma & Reactive Gas). The company is governed by a board chaired by former CEO Gerald Colella and includes notable directors such as Western Digital CFO Wissam Jabre. Major institutional backing is provided by The Vanguard Group and BlackRock, which collectively hold significant stakes in the firm.
