Andy is a very helpful, knowledgeable, and fun coach! He knows how to fix bad habits and build a proper swing. He is very observant and he knows how to make the important swing changes in order to create a big improvements. He is always positive, relaxed, and fun to learn from, yet we have always worked efficiently and made a lot of progress in my 60 or 90 minute lessons. He answers all my questions including many of the little details that I am curious about and he demonstrates what to do. I was very happy that Andy didn’t ask me to change too much about my service motion. I know it doesn’t look great on video, but with his help I was able to make slight adjustments and gain more power and consistency. I worried I’d get worse before I got better, but I was thankful that didn’t happen. 6 weeks ago I’d never beaten a friend of mine, but recently I won a set against him 6-0! I trust Andy is a very good teacher for all levels, and I highly recommend him to anyone lucky enough to meet him!
