Reviews: Beginners, Parents & Pros

Trefan is an experienced instructor who can assist guitarists at any level of playing. My playing and knowledge of music theory is still progressing after several years of lessons with him. A true testament to his deep knowledge and ability to express concepts in a simple and usable way. He is always flexible with my schedule whether online or in person. A fantastic person to boot!  Highly recommended”

Trefan has been an amazing guitar teacher since I started getting lessons a year ago. I have learned so much in a small amount of time. He gives his students awesome resources that he makes himself and  great exercises to strengthen any skills students want to work on. Not only is Trefan an awesome teacher, but he is also an incredible guitarist who can play and solo to practically anything. I have had a blast being one of his students and would highly recommend getting lessons from him!!!

When I started taking lessons with Trefan, I was at a point in my playing where I was stuck. With no direction. After a short amount of time working together, he had unlocked the whole fretboard for me! If you find yourself at a plateau with your playing, you should definitely begin your journey today!

Trefan always makes me laugh. It tells you a lot about a person, but that also translates into a comfortable working and learning environment. To this day I use two major things I learned in the first lesson. Watch out because it's action packed! Tref's brain works fast and it's fun to watch and learn from him. You will be on the fast track. All it takes is passion and you will see the passion with Tref.

Trefan was the first person to teach me the beginner music theory I needed to start writing my own songs. He has that rare combination of gifted player, writer, and teacher. It's just so hard to find. He's had a major impact on my development as a musician, writer, and guitarist, and I'm so grateful to get to work with him.

Jeff Greeneberg

Trefan and I have been teaching each other things on the guitar since we were kids. To be clear, he has taught me a lot more than I ever taught him. In fact, I can't spend 5 minutes with Trefan without stopping him so he can show me what he just did. Quite simply, he is one of the better guitar players on the planet.
