I have used Ray's OK Services Inc. for over 15 years. They are always friendly, and I have never had to wait more than about ten minutes when I go in. I make an appointment, and they are good about keeping the time on it. When I ask a question, they are good about answering it. There is no run-around. They tell me what is wrong, and what my options are. They are very friendly and nice people, and they do great work. That is why I keep using them!
