Science and healthcare communications firm Spectrum has appointed Jonathan Wilson as CEO. He takes over from current CEO and founder John Seng.

Wilson joined Spectrum as president in 2014. In March, Wilson was also appointed president of GlobalHealthPR, a global healthcare agency partnership owned by Spectrum. Wilson will continue to head up the Americas hub of GlobalHealthPR and retain his role as president at Spectrum. Seng will also remain at the firm as chair. 

Wilson spent nearly 10 years at Chamberlain Healthcare Public Relations and served as president there for more than three years after taking over from founder Richard Chamberlain. He also spent time at Ketchum earlier in his career.

Spectrum was founded by Seng in 1996. It is headquartered in Washington, DC, with offices in Chicago, New York, and Atlanta.
