What Our Customers Say

“Our company worked intimately with and relied heavily upon McLellan Engineering. We could not have succeeded as quickly as we did – designing and readying our new consumer product for the marketplace – without their expertise and industry insight.

Seth Hodes

“Working with McLellan Engineering made my invention a reality. Bruce not only provided great insight to my project, he took the time to discuss the entire process of designing, manufacturing and bringing the invention to market. I highly recommend using McLellan as a resource for any new product.”

Lisa Illman President, Kritter Kommunity

” McLellan Engineering’s services are outstanding. We have hired them for multiple medical device design and development projects and they have consistently exceeded our expectations in quality, innovation and design. Bruce McLellan’s very knowledgeable background in rapid prototyping of small parts combined with his innovative designs makes McLellan Engineering a valuable engineering tool for any company.”
