“Triple i mandolin”

I am a sole proprietor luthier shop located in Denver, CO. I have been building stringed instruments since 2003 and setup/repair services since 2016. Most of that time I have been building custom stringed and fretted instruments, centered on the mandolin and mandolin family. I use high quality materials and hardware, sometimes even sourced locally by myself! I use a mixture of modern and traditional techniques aimed at producing the most responsive, balanced and soulful instruments I can. Every instrument I make is one I would keep for myself. The wait time is about 6 months from order to completion. You can see more details in my Instruments page.

See the links below for my online building course done with Robbie O’Brien and the Luthier Academy. We filmed nearly every minute of me bulding an A-style mandolin in Robbie’s shop and cut the footage down to just under 14 hours of instruction. The course comes with instrument plans drawn by me as well as the video which you can stream or download. After looking at all other options of learning how to build this is by far the best value in how much you get vs how much you pay. See more links below!

I will have a lot to share about modal analysis, deflection and an enormous data collection project I’ve had going for a few years. Stay tuned as I get it all organized!
