My experience with Mark as been just what I had hoped and more. As an adult student with no formal training I was thrilled to find the reviews on Thumbtack about Mark were true. I have enjoyed my lessons so much, Mark is extremely knowledgeable, very patient, and has a flair for teaching the guitar. The lessons are always light and fun, he truly cares that you also understand the instrument. I feel he gives so much because he truly cares for his students, loves teaching and the guitar.
