  • "Dr. Tretter is the best dentist I've ever had. Every time I go to have work done, I feel relaxed because I know I am in good hands. I cannot imagine a more competent dentist. All the others on the staff are very professional and extremely pleasant. I know it's hard to believe, but I actually have fun whenever I visit the practice. Dr. Tretter keeps up with the latest dental technology. A crown is completed in one visit, about 2 hours long."
