Our Staff

Don Senft


Don is a native of Lancaster. He retired from the Marines in October 2006 after completing a twenty year career. His transition into the stone and tile business began when he was hired by Banta Tile & Marble in the fall of 2006 to manage the fabrication shop and installation schedule and additionally to work as an estimator. He worked at Banta until December 2009 until the company was forced to close its doors and file for bankruptcy due to a court ordered judgment. Don studied his options and decided to purchase Natural Stoneworks in April of 2010. He is thankful for an experienced and dedicated sales/design staff and skilled craftsman who take personal pride in their work, making Natural Stoneworks the best in the area.

Mary Senft


Mary works primarily in advertising and also purchases sinks, showroom and fabrication equipment and tools and handles the partial-slab inventory.

Mary is a Long Island native, settling in Lancaster, PA with her family after her husband Don retired from the Marine Corps. She was a stay at home mom until she took a full-time position with HIA-TSA in 2002. When Don acquired Natural Stoneworks in 2010, Mary worked part time in the business, while still keeping her full-time position at HIA-TSA. She loved the stone business so much that she decided to leave HIA-TSA in 2012 to work full-time for Natural Stoneworks. She and Don now run the business together and really enjoy the challenge.

Mary also handles Natural Stoneworks donations to charities and will hold their third birthday celebration in Leo the poodle's honor to benefit the Humane League and homeless pets. See more details on our events page.
