For some reason Peak Dental let me paint on their walls, and I had a ton of fun doing it! Peak Dental is in Falmouth, ME and one of the most amazing offices I've ever seen (and I have seen a LOT of dentists). They are completely "green", use no harsh chemicals, and all digital x-rays. On top of that they do exceptional work and are so nice and friendly! If you are in the area I would definitely give them a visit. They are running a promotion for new patients too.
Since they were open to ideas, I suggested a circus themed mural with funky whimsical characters for their children's area. It took about 13 hrs to complete.
