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
