IDEXX Laboratories CEO resigns; replacement named

IDEXX Laboratories Inc. said Jonathan Ayers is stepping down from his roles as chairman, president and CEO of the company.

Jonathan Mazelsky will take over as president and CEO, according to an Oct. 24 news release. Mazelsky was serving as interim president and CEO of IDEXX since June 28 after Ayers took medical leave due to a bicycling accident, where he suffered a spinal cord injury.

The Westbrook, Maine-based medical-device maker named Lawrence Kingsley, the company's current lead director as independent chairman of the company.

The management changes are effective Nov. 1.

IDEXX said Ayers will continue as a member of its board and serve as a senior adviser to the company.
