Mayer lived in Robbinsville with his wife, a teacher in the Robbinsville schools, and their three children. He was a principal in the nearby West Windsor-Plainsboro Regional School District before he was hired as the superintendent in Robbinsville.
"Steve was an incredible part of our community," Robbinsville Mayor David Fried said. "He was our superintendent, he was a coach, he lived here, and he was a friend...I think the whole community needs a time to mourn. I'm trying right now to be strong as mayor, but I intend to go home shortly and have a good cry for my friend."
"In honor of Dr. Mayer, we will find our way back to normal, as appropriately as possible," Robbinsville School Board President Matthew O'Grady. "Steve always put the students' needs first, and we will continue that as we work through this devastating loss."
Word of Mayer's passing came Tuesday morning in an email message sent to parents by the school board:
