New York-based brokerage Integro Ltd. has appointed John Clements as chairman of the board of directors and Rocco J. Nittoli as vice chairman of the board. Integro is also forming a five-member executive committee to assume management responsibilities in wake of the departure of co-founding President and Chief Executive Officer Peter Garvey.

Integro declined to comment on why Garvey left the firm, except to say in a statement, “The company wishes Mr. Garvey well in his future endeavors.”

Clements has been a member of the Integro board since the firm’s founding in 2005 and recently served as vice chairman. He is the son of the late Robert Clements, a global insurance industry leader who helped start several insurers including Arch Capital Group and Ironshore as well as brokerage Integro.

The newly formed executive committee consists of: Marc Kunney, president of North America operations; John Sutton, president of international operations; William Goldstein, president and chief operating officer; Toby Humphreys, chairman of Integro Insurance Brokers Ltd.; and William P. Costantini, managing principal and general counsel. This executive committee will assume management responsibilities, including those of Garvey, Integro said.

Founded in 2005, Integro is headquartered in New York City and has additional U.S. offices in Atlanta, Boston, Chicago, Nashville and San Francisco, as well as international offices in Bermuda, Canada and the U.K.
