Oleg Mashtaler keeps the Harvard Business School campus running behind the scenes. As a daytime operator in Facilities, he walks miles each day, managing HVAC systems across all 36 buildings, monitoring equipment, troubleshooting issues, and responding to service requests. Originally from Ukraine, he also brings his expertise to an unexpected role—he’s known by his team as the “koi whisperer,” ensuring the Class of 1959 Chapel’s 17 fish thrive.
