Review of Dr. Schmidt


Dr. Schmidt is the BEST doctor that I have ever seen! Hes so caring and actually listens to everything I have to say. He works with me to provide a treatment plan that I am comfortable with, and has never pressured me into any surgeries that are not going to help me. I appreciate the time he has taken with me and has walked me through every process. I will recommend Dr. Schmidt to every one I can! Thank you Dr. Schmidt for being a great physician

Review of Dr. Kandula


I would not recommend Dr. Kandula or going to see any of his PA's or staff because you will not get answers. I had a CT scan done years ago and he does a poor job of explaining it, telling you that your options are the balloon sinuplasty or the traditional surgery. So I went with the balloon sinuplasty. I have been a chronic sinus sufferer and thought it was time to do something more. It has not helped, lots of $ spent, he needs to find non surgical latest treatments and get to the root of it.

Really refreshing care. I've been to many physicians through the years. I've never felt more listened to anywhere else. I feel like I am on the path to health - finally.

Excellent approach to my snoring issues. After getting no where everywhere else I've been, it's nice to have the problems fixed.

Review of Dr. Kandula

-Menomonee Falls, WI |

OUTRAGEOUS AND UNETHICAL BILLING PRACTICES/CHARGES. I saw Dr. Kandula for a balloon sinuplasty. It is camera guided tube into the nose that when the doctor presses a button dilates the sinus drainage hole for 10 seconds to 6mm to help sinus drain. The procedure took a total of about 20 minutes in his Wauwatosa office. This is the procedure he promotes daily on local radio and TV. When I looked at my insurance claim form, I saw that he billed my Humana insurance $37,300 for the 20 minutes.
