Organization
Harbor Contracting
Title
President/Owner

Peter A. McKellar IV leads Harbor Contracting as president and owner, a 26-employee construction firm he joined as a high school laborer and never left, working his way through every level of the organization.

A Clemson University graduate with a bachelor’s degree in building science and management, McKellar recently promoted his sons Andrew and Alex to vice presidents, continuing the family’s leadership tradition. The company relocated to new headquarters at 835 Lowcountry Boulevard in Mount Pleasant.

“The best advice I’ve ever received is to stay in your lane and do a few things very well,” he says, emphasizing focus over chasing every opportunity.

McKellar identifies labor shortages, aging workforce, and supply chain issues as industry challenges, noting these cycles recur and require adaptability.

His community leadership includes serving as president of Center of Birds/Avian Conservation Center and board member of Detyens Shipyard and ServisFirst Bank. A 22-year Rotary Club of Mt. Pleasant member, he earned the Service Above Self Award and previously led the Charleston Contractors’ Association and Charitable Society of Charleston.

McKellar defines success through honoring promises and client satisfaction rather than awards or recognition.
