Mark III Construction Appoints Randall Christiansen as Chief Operating Officer

SACRAMENTO, Calif. — Mark III Construction is excited to announce the appointment of Randall Christiansen as its new Chief Operating Officer (COO). This strategic move represents a key milestone in the company’s ongoing growth and commitment to excellence in the construction industry.

Randall Christiansen brings more than 20 years of operational leadership experience, particularly in the power and industrial construction sectors. For the past nine years, he has served at MasTec, Inc. (formerly Henkels & McCoy), where he held the position of Senior Vice President, Growth and Strategy. His deep expertise in operations, financial management, and leadership makes him an ideal fit to guide Mark III through its next phase of expansion and operational efficiency.

This transition in leadership is part of Mark III’s strategy to solidify its position in the industry as it continues to grow and diversify its operations. Dan Carlton, the company’s President and owner, has led Mark III for nearly 18 years, overseeing both executive and operational roles. With the addition of Randall Christiansen as COO, Dan will now shift his focus toward fostering innovation, driving company culture, and advancing the company’s long-term vision and strategic initiatives. This allows Dan to further develop Mark III’s broader goals while ensuring day-to-day operations remain in capable hands.

“Mark III has reached a pivotal moment in our journey, and bringing Randall onboard as COO strengthens our ability to meet industry demands and pursue long-term success,” said Dan Carlton. “Randall’s operational expertise and leadership will be instrumental as we continue to innovate and adapt to new opportunities in the construction space.”

With Randall leading operations, Mark III is poised for a new era of growth, focusing on operational excellence and strategic innovation. This leadership shift ensures that Mark III will continue to deliver top-tier results while preparing for the future with an even stronger foundation.
