Accomplishments
To Whom It May Concern,
As a dedicated Electrical Maintenance Supervisor and certified NFPA 70E and MSHA Lockout/Tagout (LOTO) Trainer, I take pride in my measurable contributions throughout my career to enhance electrical safety, operational efficiency, and team performance.
One of my core accomplishments has been developing and delivering comprehensive electrical safety training programs, including NFPA 70E and MSHA-compliant LOTO procedures. My efforts have empowered maintenance teams to work safely around energized equipment, resulting in zero reportable electrical incidents under my supervision for over thirteen years. I’ve trained new hires and veteran personnel, tailoring instruction to various skill levels and shift needs.
In my leadership role, I supervised a team of 8 electricians and maintenance technicians, streamlining preventive maintenance schedules and participating in developing a predictive maintenance program. I am also proficient in SAPPM a CMMS, to improve work order tracking and asset management, cutting response times and improving workflow visibility.
I successfully led many projects to electrical system upgrades, completing the project ahead of schedule. By coordinating closely with production, safety, and engineering teams, I ensured minimal delays and change orders while maintaining budget and could complete jobs with shortened deadlines.
Another point of pride is my role in mentoring and developing junior technicians. Several team members I’ve trained have advanced into lead or supervisory positions. I believe firmly in cultivating talent and creating an environment of mutual respect, accountability, and continuous improvement.
In every role I’ve held, I’ve maintained a strong focus on compliance, efficiency, and above all, safety. Whether responding to emergency breakdowns or leading long-term capital projects, I approach every challenge with diligence, clear communication, and a commitment to excellence.
Sincerely,
Nathan Dennis
