Who We Are
Putting Customer Success First Driving Innovation Since 1998
Driven by Customer Success, Built on Innovation
At Custom Milling & Consulting, LLC (CMC), our guiding principle has always been: “Make our customers successful first, and our success will follow.” Founded in 1998 by Carl Yerger and Joseph Zidik, CMC began as a small toll processing company specializing in particle size reduction for liquid materials. By staying true to this belief, we have continuously evolved to meet the changing needs of our customers.
As demand grew, so did our operations. In 2010, we built an additional state-of-the-art facility dedicated to assembling and constructing equipment. This facility also houses our Pilot Lab, where customers can test our technology firsthand to see the impact CMC equipment can have on their processes.
A Unique, Full-Service Approach
What sets CMC apart is our full-service approach. We not only design and build equipment but also use our own mills in our toll processing facility. This gives us a deep understanding of real-world production challenges.
Whether you’re outsourcing production or transitioning to an in-house operation, we make the process seamless—replicating exact setups to match your specific needs. For companies developing new products, we offer small-batch processing, providing the flexibility to scale up without the immediate investment in new equipment.

Carl D. Yerger Logistics Center: Expanding Capabilities
In 2014, we took another step forward by establishing the Carl D. Yerger Logistics Center to support customers developing specialty chemicals requiring extended processing times and precise conditions. It provides on-site warehousing for raw materials and finished products, as well as large-scale toll processing for production-size batches.
In 2021, CMC became part of the ChromaScape LLC family, further strengthening our ability to deliver innovative, customer-focused solutions.
At CMC, our focus remains the same as it has been since day one—delivering innovative solutions that help our customers succeed. Contact us today to learn how we can support your business.
