Goff replaces Arkles as CEO of Gelest Inc.

MORRISVILLE, Pa.—Gelest Inc., a manufacturer and supplier of silicone, organosilanes and specialty monomers, has made its first change in the top executive role since its founding in 1991.

Gelest founder, Barry Arkles, stepped down as CEO and was succeeded Jan.3 by Jonathan Goff, a 13-year veteran of the company who most recently served as chief technical officer.

Arkles began the company to develop and manufacture silicon and metal-organic-based chemicals. The longtime CEO has accepted the position of Distinguished Adjunct Professor at Temple University.

"I couldn't be more pleased to have Jonathan take over the reigns at Gelest," Arkles said. "His strong grasp of the technology and markets and a leadership style that is at once inclusive and directional gives all stakeholders assurance that the strong growth and innovation that characterizes Gelest will continue.

"Jonathan brings palpable excitement and creativity to Gelest in his new role."

Goff's career focus on technology, customer relationships and new product development gives him excellent background for his new role with Gelest, Arkles said.

He maintains a doctorate in macromolecular science and engineering from Virginia Tech University and has more than 60 patents and publications.

"I am excited to take on this new role," Goff said. "Gelest has a strong technology road map for the years to come thanks to the entrepreneurial vision of our previous CEO. We are well-positioned for strong growth, and ... we will continue to drive through new frontiers of technology and innovation."

Gelest inc. is a subsidiary of Mitsubishi Chemical Corp.
