Tenorio Werx

We build guitars, we repair guitars, we know guitars


“Going to Tenorio Werx was a serious wake up call for me. Prior to that I had no idea what to expect from a guitar tech; I had seen several others who merely took my guitar, did a general adjustment, and handed it back to me a few weeks later with little to no comment. On my first visit to Mark Tenorio, we spent about an hour just talking about my playing style, guitars I like, what I expect from a guitar, which frets I favor, etc. – all before he even looked at my guitar. I left raving to friends that I had found a guitar spa!

Over the years I have taken almost every guitar and bass I own there. Without fail if I’m on a gig and a fellow musician plays one of my guitars, their response is: “Who set this up?! This plays amazingly well!” Mark caters his setups and adjustments to my individual playing style. One of the many things I have learned from him – having also taken a class from him – is that guitar setups are no easy feat! They are as unique as the player playing the instrument. It is a mix of science and art to arrive at the perfect setup for each individual.

I refer all my musician friends and students to Mark. Major bands coming through town send their guitars to him. I personally look forward to going to his shop because I always learn something new. In a world of hobbyists turned professionals, Mark is someone who has extensively studied his craft, even to the extent of studying luthiership in Spain. He teaches classes on guitar maintenance and building, and even takes on worthy apprentices. I don’t know of anyone else who is as accomplished in the field. Mark Tenorio is a true master craftsman, blending science and art in a continuous path towards perfection.”

“I have been a professional musician for over fifty years. The first twenty plus years I bounced around from one Luthier to another, never quite satisfied with the product I was receiving. One day in the late 80’s I was visiting my local Prosound Music Store picking up a few things and commenting on my need for some service on my guitar. The gentleman behind the counter said “today is your lucky day” (little did I know how true his comment would turn out) and said “how so”?  He said “That is what I specialize in”, the man was Mark Tenorio. From that day forward Mark is the “Only” Luthier to work on my guitars. He is a true genius when comes to making your guitar/guitars as good as they can possibly be.

He founded Tenorio Werx in 1999 and after establishing himself as The Premier Luthier in Colorado he decided to pursue the art of building guitars. He packed up his bags in 2002 and headed to Spain to study with Jose Romanillos. When Mark returned to Colorado and began building his own signature guitars and has never looked back.

No matter where you reside within the Rocky Mountain Region you won’t go wrong making a trip to Denver for his expertise. For my money it gets no better than Mark and Tenorio Werx!”

“Mark and I have been friends for years and as long as he’s been exclusively been working on my guitars… If you’re in need of any type of work on your instrument, look no further than Tenorio Werx (303-722-4887). Only Mark werx on my Paul!”
