Client Feedback
Kind Words From Our Clients
See how our hands-on approach, listening, and real expertise make a difference.
Andrew is extremely experienced, knowledgeable, versatile and efficient. He has a broad spectrum of engineering capabilities from inception through production. He is easy to work with and communicates well. We have contracted him to work on existing and new designs and concepts creating CAD models and drawing sets, as well as, simulation and FEA studies even before he started NZN Solutions.

Andrew Letton from NZN Solutions provided excellent service at our 70‑unit apartment building. He was professional, knowledgeable, and very easy to work with throughout the process. Andrew clearly knows his field, and the quality of the report gave us great confidence. We’ve already implemented suggested strategies for cost savings. Highly recommended.
