Who we are
My name’s Jake Miramontes, and equipment repair has taken me places I never expected.Over the last 11 years, I’ve spent my time chasing knowledge, honing my skills, and learning how to deliver real value to the people who rely on their equipment every day. I’ve timed hay balers in the middle of summer heat, worked late nights fighting waves while diagnosing marine engines on Lake Michigan, and traveled across the country learning from some of the best technicians in the industry.That experience is backed by 450+ hours of OEM technical training, earning three Master Certifications and more than 20 additional certifications across a wide range of equipment and disciplines.Whether it the construction site, the fields, the fleet yard or your front yard. I take pride in being the guy who shows up, figures it out, and gets it done right. No shortcuts. Just solid diagnostics, honest work, and repairs you can trust.At the end of the day, my name is on the work, and I treat every machine like it has to earn its keep tomorrow morning.
