About

I take every job seriously — no job is too small. When I served in the U.S. Army, I worked on helicopter repairs, where attention to detail was critical because lives depended on the quality of the work. I’ve carried that same discipline, precision, and responsibility into my civilian career. I provide a wide range of services including carpentry, electrical work, plumbing, appliance repair, grill repair and cleaning, lawnmower repair, treadmill repair, and more. I take pride in doing the job right the first time and delivering dependable, high-quality work for every customer.

Before initiating the original repair I hired him for, he exhausted all possibilities for the issue and found the solution was something very simple and far less costly. He solved a problem other professionals could not. Very pleased with the result.

Val showed up when expected, got right to work and had my treadmill up and running in short order. It may need some parts which is checking on but I can use it in the meantime. His service call price was a little high but he did a great job.
