About us

Who we are

Founded in 1992 by two Polish immigrants with a passion for craftsmanship and problem-solving, RTM Precision Machining has grown from a small toolroom into a trusted, family-owned CNC machining partner serving industries that demand accuracy and reliability.

For more than three decades, RTM has stayed committed to the values that built the company: quality work, honest communication, and dependable delivery. Still operated by the family of one of its original founders, RTM continues to grow through long-term partnerships and referrals — not high-pressure sales.

Whether you need a single prototype, a repeat production run, or a complete machined assembly, you get the same thing every time: accountability, transparency, and pride in the work. At RTM, precision isn't just what we do — it's who we are.
