Shepherdsville, Ky, Us

Role listed

Shepherdsville, Ky, Us

Director Of Operations

Keene, Nh, Us

Most recently, I was recruited to stabilize a facility facing challenges—high leadership turnover, low morale, lack of trust, and an absence of structure. The operation had cycled through three directors in as many years, leaving the leadership team underperforming and expectations unclear.By fostering direct engagement, hosting monthly town halls, and actively investing in people, I transformed the culture and boosted employee attendance from 68% to 95%. I instilled structure, accountability, and a sense of purpose across the team, revitalizing the facility and laying the groundwork for sustainable success.I collaborated with the corporate team to re-tool the training program, introducing a trainer/trainee scorecard and weekly milestones, fostering ownership among trainers. These initiatives helped transform the facility, driving consistent success and positioning it for long-term growth. Under my leadership, the team set company records, including 120 days injury-free for the first time in five years. We also launched a Safety Committee and Incident Review Boards to reinforce a culture of safety.When the time came to pass the reins to a new director, the operation was set on a winning trajectory, with a solid foundation built on trust, clear expectations, and improved communication. The transformation was evident, and the path forward was secure.
