About Mark

Mark Leffingwell is a trusted and highly knowledgeable real estate professional who calls the Swan Valley home year-round. Combining a strong foundation in construction and project management with deep local insight, Mark helps clients navigate every aspect of buying, selling, and managing real estate with confidence and ease. As a REALTOR®, Montana Licensed Property Manager, and Registered Independent Contractor, he provides a full spectrum of services for property owners and investors seeking thoughtful guidance and expert stewardship. A passionate advocate for conservation-minded development and historic property revitalization, Mark brings a careful, detail-oriented approach to every project. He moved to Montana from his native Wisconsin in 2005 to pursue an engineering degree and quickly fell in love with the region’s rugged beauty, outdoor lifestyle, and tight-knit communities. Outside of real estate, Mark enjoys connecting with the landscape he loves through hiking, skiing, and wildlife tracking, often accompanied by his partner, Jackie, and their two German shepherd mutts. With Mark, clients gain not only a skilled professional but also a local partner who truly understands the Swan Valley way of life.
