Customer testimonials

Why do our customers recommend Acuantia?

I selected Acuantia because of their engineering expertise i.e. Les Miyashiro, consulting engineer. Les is recognized for his ability to engineer for even the most complicated situations. He’s done work for me in the past. I’d bet on Les to get just about any project approved.

Acuantia’s pro did an outstanding job assisting our family with all the septic and environmental issues we faced over several years. We would not have had the successful subdivision without his caring support and expertise. He is committed loyal and one of the best, I highly recommend his services.
