Friday will be Green Brook Schools Business Administrator Michael Colling's last day in the district, after he gave notice to the district that he accepted a position with the Medford Lakes school district.
"We all wish him the best," Superintendent Rick Labbe said, adding Colling lives near Medford Lakes and the change will end his nearly 90-minute commute to Green Brook.
Colling had been in the district for about 18 months.
The Green Brook Board of Education approved hiring Gregory Brennan, a 19-year employee of the West Orange School District.
"We're real excited to have him come aboard," Dr. Labbe said. "Greg is someone who has exceptional capabilities."
This will be Brennan's first posting as a business administrator.
