🔊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*

2011 📆⏳🔐🏭 2026
🎉~ time goes by so fast🎉~ 15 years ago we took the leap to purchase our own property & move the established business to our current location ~ now we’re looking to start transitioning towards our retirement & let the next generation continue the journey.

NO we are NOT retiring this year (or next) ~ it’s a process but one that doesn’t happens overnight!! Still so much to do & having a goal to work for is motivation moving forward.

Just here to celebrate the milestone not start the rumor mill🤦🏻‍♀️

01/23/2026

We decided to CLOSE early today so our employees can make it home safely for the remainder of the weekend. Back to business as usual on Monday.

Safe travels & stay warm if you’re out in these extreme temps 🥶
