Alex is awesome! We've had him do all sorts of work over the years, and he never disappoints. He's highly skilled, very responsible and HONEST. He remains our first choice if we can get him! I believe his first language is Russian, but I've never had issues understanding his explanations in English. He's a very patient and likable guy as well. Hire him!
