About Dennis O.

Dennis Guitar Instruction is a Denison, TX based proprietor founded in 1995.
It all began as a 'favor' for a few friends by helping them learn the theory portion of playing guitar. Once word began to spread, Dennis Guitar Instruction was officially born. The main focus of the private lessons is music theory and how it applies to the instrument. All the while trying to remain fun. Therefore, all musical styles/genres are obtainable. My goal is for the student to have an understanding of the music which they seek to learn and become an independent musician. Since it's inception, I have helped thousands of players from around the world learn how to play.

I encountered Mr O. looking for a guitar instructor formy grand daughter and found not only a talented musician,but a gifted instructor as well. My grand daughter is motivated and enjoys practicing, and I am enjoying the fruit of his labor.

I had him two separate times whenever I was younger. He’s great at what he does, super patient, very kind, I felt 100% comfortable. He’s keeps his work professional and you don’t feel judged if you don’t know what you’re doing and slower than others at learning guitar. Would reccomend!
