Summary
Hands-on diesel mechanic with experience diagnosing, repairing, and maintaining heavy-duty semi trucks. I take pride in finding the cause of a problem, getting the repair done correctly, and making sure the truck is safe and reliable when it leaves the shop. I have experience working with PACCAR MX engines and Allison 1000–4000 series transmissions and have continued to build my skills through hands-on work and additional Peterbilt technician training. I am dependable, safety-minded, and comfortable working independently or as part of a team in a busy shop environment.
