As we head into the start of our 24th year ~ we want to thank our family & friends who have supported us, the customers that keep us going year after year & our employees past/present that have contributed to our longevity this far.

This industry is nothing if not unpredictable & no 2 days are ever the same in the shop but we’ve learned to go with the flow of it all & remain confident in our ability to sustain & improve upon our services despite the crazy state of our country & economy the last few years.

We are looking forward to adding to our crew & customer base in the coming year(s) with your support.

We’ve rebranded in 2026 with our new logo(s) & new apparel will be available to order soon!

~ THANK YOU for your support thru the years ~
Kevin & Tina

🔊ANNOUNCEMENT🔊

You know him (we love him) & you know his work, his attention to detail, his calm demeanor & sometimes his quick wit ~ we are excited to let everyone know Jeremy has been promoted to the position of SHOP MANAGER 🙌🏼

His daily role as our main motor guy & in-house machinist will not change. This promotion just gives him a bit more responsibility in the daily operations to oversee scheduling, deligating workflow, handling customer relations & assisting Kevin with shop needs/wants moving forward.

After 13 years under our roof it was only fitting to place him in this role as he takes on a lot of extra when we can’t be at the shop.

Yes Kevin will still be at the shop but his goal is to focus on diagnostics & motor work, bigger shop projects & some facility maintenance.

*if you know him but haven’t been to our shop yet ~ stop in, say Hi & see what we’re all about*
