• Dear Hiring Manager and Selection Committee
• With nearly 30 years of hands-on and executive engineering leadership across heavy industrial manufacturing, brick production, aggregate processing, power generation, and commercial fleet management, I am writing to express my strong interest in joining your team. Throughout my career, I have specialized in building high-performing maintenance teams, optimizing asset reliability, and driving bottom-line production performance across complex, multi-site industrial operations.
• In my most recent role as Chief Engineer / Maintenance Manager across Pacific Clay, Pacific Aggregates, and Rancho Ready Mix, I directed multi-site maintenance and plant operations across seven facilities. Managing a $1.62M annual budget and coordinating schedules for 135 direct personnel and a broader workforce of ~300, I focused on transitioning reactive repairs into disciplined, reliability-centered programs. Through targeted overhaul schedules and root-cause failure analysis, I elevated site-wide equipment availability from 82% to 94%. My responsibilities spanned complex brick manufacturing systems—including automated setting robotics, extruders, and kilns—as well as aggregate machinery producing 10,000+ tons of washed sand daily, where we raised uptime on critical screens and sand screws from ~75% to 98%.
• Additionally, I managed fleet maintenance and lifecycle strategy for 51 mobile assets, including a core fleet of 33 ready-mix trucks and 18 pieces of heavy earthmoving equipment. Beyond technical reliability and fleet engineering, my leadership style centers on workforce development. I have consistently built long-term operational strength by instituting hands-on technical training for technicians across all facilities, significantly reducing external contractor dependencies while improving safety and troubleshooting autonomy on automated systems.
• Supported by a B.S. in Electrical and Mechanical Engineering from Cal Poly Pomona, I bring a rare combination of deep technical expertise—spanning 480V power systems, PLCs, industrial robotics, and heavy machinery—alongside executive operational discipline. I would welcome the opportunity to discuss how my background in multi-site maintenance management, robotics, and capital planning can support your production goals.
• Thank you for your time and consideration.
• Sincerely
