Dr. Reagan has been practicing dentistry since 1986. He and his wife have been married since 1990; together they have 2 children and a dog. He enjoys hiking, traveling, masonry/tilework, gardening, skiing, and visiting museums.
On many occasions, patients have come into the office with severe breakdown of their front teeth. They consciously make an effort not to smile and it affects their entire demeanor. After restoring their smile, I have seen a complete transformation in their personality and outlook on life. Making a difference like that in someone's life is very gratifying!
