I have used Dmitri before for other jobs. This was to replace a cracked floor tile, laid by another contractor.
You are not going to find a more polite, knowledgeable, and friendly contractor. I can not praise him enough for his attention to detail, even on such a small job. He truly wants to make sure you are 100% happy and I am a very picky guy.
He is my go-to guy when it comes to tile.
