Teaching since:

Dennis O'Toole 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 O'Toole Guitar Instruction was officially born. The main focus of the private lessons is music theory and how it applies to the guitar. All the while trying to remain fun. Therefore, the musical style/genre which the student is seeking is irrelevant. My goal is for the student to have an understanding of the music which they seek to learn and become an independent guitarist. Since it's inception, I have helped thousands of players from around the world learn guitar theory.

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.

Not knowing the first thing about playing guitar, Dennis has taught me and gave me confidence to continue my guitar playing dream!!

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!

My son had his first lesson last week & cannot wait to go back this week! So excited we found someone who knows what they’re talking about and can break it down so easily for my little beginner!
