I'm in need of a surgery to avoid another ER visit. I set up and had my appointment. Per their request needed blood drawn. Completed the immediately after my appointment. Doctors assistants don't return calls. When you I actually reached someone they told me they were waiting on my insurance to approve. Called insurance the next day to rush it through. Insurance had not received anything from them. Called back multiple times again to get in touch with the assistant only to be told now that the doctor wanted to look at my blood work before he would send the request to insurance. So why tell me one thing and then change it the next day? Giving a two star ONLY because Dr Hillmann himself was extremely nice and very personable. The staff including his assistant are completely worthless.
