"I went to see Dr. Mueller last week. His office staff is great and so is he. Very personable. He didn't rush me and allowed me to ask all the questions I wanted to ask. I asked about their mortality rate (which is zero), their leak rate (2 leaks in the last 2.5 years), their obstruction rate (2 obstructions in the last 2 years), etc... Them odds sound good to me! All in all - Dr Mueller is awesome!"
