Spencer Svonavec
Founder, Rockwood Stone & Simkol Corp | Rockwood, Pennsylvania
Fourth-Generation Miner. Pennsylvania Certified.
Spencer Svonavec is the founder of Rockwood Stone and Simkol Corp, operating certified surface mining and aggregate production across Pennsylvania and Maryland. Rockwood Stone holds Pennsylvania’s highest aggregate designation — Type A, Class E, listed on Bulletin 14 — and employs 55 people from its headquarters in Rockwood, Somerset County.
Areas of Focus
Aggregate Production
Type A, Class E certified aggregate supply for PennDOT and state-funded projects. Quality stone sourced from Somerset County’s geology, tested and documented to Bulletin 14 standards.
Surface Mining Operations
Responsible extraction across Pennsylvania and Maryland, with land restoration built into operations from the start. Dependable production schedules backed by an experienced team of 55.
Community Investment
Rockwood Stone has donated and built the GAP Trailhead entrance in Rockwood, expanded the American Legion Post 279 parking lot, and supplied aggregate for the Somerset Playground Splash Pad.
Background
Spencer Svonavec is a fourth-generation miner and a Pennsylvania native. He trained alongside mechanics, welders, equipment operators, and farmers, and graduated from PA Cyber School in 2022 after arranging early morning study blocks so he could apprentice during the day. That approach — building real skills through work, not around it — has defined how he has run his companies since.
Today Rockwood Stone is Pennsylvania’s highest-certified aggregate producer in Somerset County, and Simkol Corp extends his operations across the region. Spencer believes responsible extraction and community investment are not competing priorities. At Rockwood, they happen at the same time.
