Dr. Charles Lewis sold the practice and house to Dr. Jon Wigert, who lived here and continued the practice until 1990 when Tri-County Hospital in Wadena built a new medical facility a block away. The Espeland family provided the funds to buy and renovate this facility for the City of Henning. The Landmark Center opened in 2009. Meetings, retreats, and other functions are held on the main floor of the residence and the second-floor bedrooms are used for over-night accommodations. The 1948 addition houses offices, meeting space, and a museum. The building was added to the National Register of Historic Places in 2021. A two-stall garage (c. 1920) is also a part of the historic designation.
