Mario Machnicki is the president and CEO of American Lime Technology. A native of Poland, he learned traditional masonry construction skills in Eastern Europe. After establishing a successful masonry restoration business that employs old-world techniques and materials in his adopted home of Chicago, he founded U.S. Heritage Group, which offers traditional masonry materials, heritage tools, training, and specialized consulting services. American Lime Technology combines Mario’s interest in heritage masonry with his appreciation for the inherently sustainable qualities of traditional construction methods and natural materials.
Mario’s projects include work on the United States Capitol, Frank Lloyd Wright’s Taliesin, and Castillo de San Marcos in Saint Augustine, Florida. He has participated in traditional masonry training courses in Poland, England, Austria, France and Ireland. He is a popular conference speaker and has been featured in national newspapers, radio and industry trade magazines.
