What Our Clients Say

“Stewart Technology have been the perfect partner for us. The management team understand the development challenges of small businesses trying to get to the next level and have been supportive in a way that, not only has gone beyond expectation, but has allowed us to push through several detailed manufacturing issues which, without their support, would not have been solved in time or possibly, at all. The past 18 months engagement with the team at Stewart Technology have been an absolute pleasure.”

VP of Operations, Wireless Technology Company

“Working with Stewart Technology has been an exceptional experience. They have been very reliable for us as a business, and are very proactive and practical in approach to continuous improvement of product and process.

John Robertson and his team are friendly, approachable, highly knowledgeable and technically skilled. Their flexibility, attention to detail and cost-competitive approach have been invaluable to us as our product has evolved. An experience for us that has not been matched by many other contract manufacturer we have worked with. This along with their location, make them stand out in the industry.

We have complete confidence in Stewart Technology’s technical capabilities, and would not hesitate to recommend them.”
