President
Tanya DiSalvo leads Criterion Precision Machining as its third-generation owner, carrying forward a legacy of precision excellence that stretches back to 1953. Under her leadership, Criterion has expanded its capabilities in medical device machining—including catheter component production—while earning ISO 13485 and ISO 9001 certifications and achieving FDA and ITAR registration. As a woman-owned business under WBENC certification, Tanya has championed a culture where quality is non-negotiable and customer relationships are built on trust. Her vision continues to drive Criterion's investment in advanced Swiss turning, multi-axis CNC milling, and state-of-the-art inspection technology to serve the No-Failure sectors that depend on Criterion's precision every day.
Estimator/Project Manager
Mike Pinchot serves as Estimator and Project Manager at Criterion Precision Machining, acting as the critical link between customer requirements and the shop floor. For catheter component projects, Mike translates complex engineering drawings and tight-tolerance specifications into accurate, competitive quotes and actionable production plans. His deep understanding of Swiss turning, CNC turning, and milling capabilities allows him to identify the most efficient and cost-effective machining strategies for each unique catheter design. Mike's project management expertise ensures that timelines are met, communication is clear, and every catheter component order moves from design intent through to final inspection without compromise on quality or delivery.
Quality Manager
Kelly Marflak oversees Criterion's certified Quality Assurance program, ensuring every catheter component leaving the facility meets the stringent dimensional, surface finish, and compliance standards required by medical device manufacturers. Kelly manages a multi-layered inspection process that includes a Global Advantage CMM with TESTASTAR-sm probe, the OASIS Optical Automatic Smart Inspection System, and Keyence measuring systems capable of simultaneously measuring up to 99 dimensions on 100 parts. Her leadership of the QA team is central to Criterion's ISO 13485 and ISO 9001 certifications and the company's reputation for delivering zero-defect catheter components to customers across the United States.
What is the process of catheter tip forming?
Catheter tip forming involves precision machining or shaping of the distal end of a catheter to achieve specific geometries, angles, and surface finishes that enable smooth insertion and accurate placement. At Criterion, we use Swiss turning and CNC turning to machine catheter tips to tolerances as tight as ±.0002", ensuring consistent geometry, biocompatible material integrity, and a smooth finish that meets medical device specifications.
