Years ago a friend recommended Dr. Trepp. I expect many of his patients found him this way. That said, if you're looking for a new dentist, and are looking at online reviews, Dr. Trepp should be on your list.

JoAnn the hygienist cleans my teeth thoroughly. Since I switched from 6 month cleaning to a 4 month cleaning my teeth stay whiter.

Everyone in the office is professional and pleasant.
