I wasn't worried about their equipment. It was safe and well taken care of. They have a very good professional reputation. I know that I'm under the care of an expert. One thing I love about them, is that they're always willing to ask for other qualified professionals' advice when they don't have an answer for my question. I never have to worry about them giving me a wrong answer just because they weren't willing to ask for help. They are always prepared for my appointment and remember everything about me.
