Founder
Larry's journey into precision calibration began on the production floor as a machine operator, giving him firsthand experience with the challenges manufacturers face daily. Recognizing that calibration was more than routine maintenance—it was the key to production quality and efficiency—he founded Sarkinen Calibrating to deliver solutions that actually work in real manufacturing environments. His operator background shapes every service decision, ensuring calibration isn't just technically accurate but practically valuable. Larry built the company on the principle that eliminating unexpected downtime requires understanding both the machines and the people who depend on them. Today, he leads a team serving Northern California manufacturers with the same problem-solving mindset that defined his early career. His vision of a world without unexpected downtime continues to drive innovation in calibration services and customer support throughout the region.
