The Old Mill, a historic mixed-use commercial building located in San Marcos celebrated its 100th anniversary on Dec. 6 with a Chamber of Commerce next century ribbon cutting and Christmas breakfast for tenants. The Old Mill is one of the oldest and historic commercial properties in the area.
Henry and Marian Oles purchased the 12-acre property in 1988 to serve as headquarters for their company, EPS Photographic, and to develop as lease space for other businesses. The property had been abandoned for several years and required extensive renovation. Since then it has been home to the first internet service provider in San Marcos and numerous other companies. Many have been startups. The primary building and its companion buildings are now occupied by a variety of companies, including counseling, medical training, rehabilitation, club volleyball, faith-based communities, physical therapy and San Marcos Consolidated Independent School District. The Mill Street Crossing shopping center was added to the complex in 2020 and has tenants, including Mill Street Market by Poco Loco, Leaf Smoke Shop and Domino’s Pizza.
“The Old Mill has been a huge part of our lives for over thirty years,” said Henry Oles. “This building’s ultra modern all concrete construction and its history are part of what makes it so special both during and after construction, and still today. We’ve worked hard to keep the building updated while respecting its long legacy.”
