I heard about Anthony & Sylvan through internet research. We have not used them for any other pool services. The General Manager, Neal, is great. He was very responsive, customer orientated, and always responsive. They were on time, extremely professional, helpful, and courteous. They kept their area clean. During the pool opening, they left things in order for us. They folded the cover, explained what they were going to do, and what they needed us to do to close the pool. I've always found them to be extremely professional, very knowledgeable, and responsive. Those adjectives are what I would use to describe our experience with them so far. I would absolutely recommend them without reservation.
