Our work is grounded in a culture of precision, accountability, and partnership. Every decision we make is driven by a commitment to safety, traceability, and continuous improvement. We build long-term relationships with clients who value quality as much as we do. Our clients trust us to deliver consistent precision because lives depend on it.
Circuitwise manufactures all products at our state-of-the-art facility in Bella Vista, in Sydney’s north-west.
Who we are
Circuitwise, formerly Tresmine Pty Ltd, was established in 1987 by Rozaline and Greg Ross and renamed in 2014.
Leadership transitioned in 2019, with Serena Ross appointed as CEO and commencing a strategic reset of the business.
We understand that your products must meet the strictest standards of manufacturing precision, traceability, and documentation, so we maintain robust quality control over our systems. Over time, we’ve evolved into a strategic partner for organisations operating in highly regulated environments. Today, we’re led by a team of experts who understand the intricacies of compliance, innovation, and operational scale, and who are committed to driving Australasian manufacturing forward.
