I hired Dr. Seth Greenberg to play guitar for my dad's 75th birthday surprise dinner at Viva Madrid! in Claremont. It was an intimate dinner and he provided great ambiance. My dad is a big Beatles fan and he played a few Beatles covers - that was a great touch! He was so easy to work with and by the time I showed up…

After about 6 months playing with Seth just 2-3x/month I’ve made more progress, been more consistent and had more fun playing guitar than I did in about 2 years of on and offing on my own. There’s no YouTube video that can replace a great teacher, continued guidance and someone with as much experience as Seth. Super…

As a 67 year old with very limited guitar playing skills, I started taking lessons with Seth a few months ago. In a very short time he’s taught me so much and I’m very pleased with the progress I’ve made. He is extremely patient, endlessly knowledgeable and fun to work with. I’m very glad I found Seth and I highly recommend him.

My son has been taking guitar lessons with Dr. Seth for over a year now, and we’ve had a wonderful experience. We were initially hesitant about online lessons, but they’ve worked out really great. Over the past year, he has learned so much — reading notes, understanding rhythm and tempo, learning different techniques, and really feeling the music.
Dr. Seth uses songs my son enjoys, which makes lessons fun and keeps him excited to learn. He’s patient, never rushes him, puts in extra effort when needed, and has been very flexible with scheduling.
We’re really glad we found him and grateful to have him be part of my son’s musical journey. Highly recommend!

Rather your beginning, or advanced and looking to learn even more, Seth definitely has the ability to help teach all. His method of teaching is very direct and makes sure all fundamentals all are understood before moving along which is very important. Thankyou Seth

Dr g is amazing person to talk to let alone musician to learn from. Every lesson I’ve had with Dr g has expanded my technical/musical ability greatly but what I valued to most is his career and life advice. He’s helped me find a lot of confidence as my own musician and that is invaluable, I believe, to any serious musician.

I am 78 years old non musician with a very modest and self-taught skills to play simple classical guitar pieces. After our first few lessons Seth was able to point out a direction for me to explore, musically and technically. His no pressure approach and willingness to deal with my lack of talent initiated a renewed enthusiasm to practice as well a audible progress in my playing.
A sincere recommendation to contact Seth for anyone looking for a true teacher.

How is this guy not a giant rockstar!?! Because he certainly performs like one! He can do a different spin on your favorite song, you won't recognize it at first, and then boom! Love his music and his playing. You must see this guy perform.

Personable, kind, a great communicator
Seth was very on top of everything he contacted me right away to figure out exactly what it was I’m looking for. He was adaptable to wherever he needed to set up. Very personable, he stayed & chatted for a while after. He had nothing but great reviews and he lived up to them. Thank you again (:
