Reviews + Testimonials


When we came to BES we were immediately impressed.

The engineers and designers were attentive to our wants and needs. Working with BES was a collaborative process which was important to us. They tackled our project with great ideas right off the bat and they were always open to hearing to our ideas. BES approached our project, with the understanding that, as a start-up, we had hefty budgetary constraints. They were able to reduce parts and assembly complexity and save us money in the long run. It's obvious that they love solving puzzles and that their client's success is their success too.

I am extremely impressed with the team at Boulder Engineering Studio (BES).

Working with BES was truly an incredible experience and opportunity. The depth and breadth of knowledge they bring to the table is unparalleled. Their ability to distil complex topics into concise, clear points for their clients is unmatched. BES is an incredibly efficient, effective, and fun partner to work with.

One of the services I provide my clients is the design of custom data acquisition systems for prototype zero energy homes.

As a mechanical engineer, I possess the skills required to create functional data acquisition systems. However, I lack the mastery of electronics required to precisely optimize the system to my clients’ technical and budget requirements. I continue to be amazed by John’s deep and broad knowledge of all aspects of electronics and sensor design. His valuable contributions to a recent project came along at just the right time…thanks again, John!

The Boulder Engineering Studio provides an incredible resource!

I was delighted that they were able to take my original concepts and wishlist and turn them into a highly functioning, sophisticated machine. From the fabrication of the parts to the design of the software, everything about the machine—a CNC device that I use for engraving and drawing—was expertly executed.
Michael Theodore

Working with Boulder Engineering Studio was one of the best choices my co-founder and I made for our project.

Not only did they produce results rapidly and exceed our expectations at each design review, but they continuously asked the inquisitive questions and helped us think through difficult problems our product faced. Everyone at BES was a pleasure to work with, I can’t recommend highly enough. Special shoutout to Ryan the renaissance man, (our lead engineer) who may be a magician.
