The Lansing Group
The Lansing Group operates as the single-family office for the Mortenson family. Mark Mortenson holds the role of President. The office traces its wealth origin to M. A. Mortenson Company, the engineering and construction firm founded by the family. The office deploys capital across public equities, private equity, real estate, private credit, and infrastructure. Confirmed investment stages include buyout, growth, seed, and pre-seed. Geographic focus remains North America. Additional holdings encompass Allianz Field in St. Paul and Yahara WINS carbon credits in Madison, Wisconsin. Team size and total deployment remain undisclosed. The office maintains its headquarters in Minneapolis. Amy Jensen serves on the Minnesota State Board of Investment Advisory Council and the Twin Cities PBS Board of Trustees. Mark Mortenson has served on the board of Alight. In 2022 the related Mortenson Family Foundation added two investment committee members and hired Ambar Cristina Hanson as executive director. The office maintains separation between its investment activities and the Mortenson Family Foundation, which was established in 1999 as an independent grantmaking vehicle. This structure allows distinct governance for financial deployment versus philanthropic commitments.
