Jack Irwin is a really nice guy. He will make you feel comfortable. He is the only dentist that my father will go to. He never leaves you waiting, and is sympathetic to pain and very easy to talk to. He will tell some jokes or stories to take your mind off the procedures. However, I have had better cleanings, and I know some people who have had to get their crowns redone. But, he is fair and honest, and does a decent job.
