I have worked with Dr. Nienaber for over 4 years now. Not once have I ever felt rushed in our appointments - he would always take the time to make sure he answered all of my questions and that I was feeling okay about what we had talked about. I always felt heard and understood. I always felt comfortable enough to ask questions I might not ask another provider. I always felt like he was immensely knowledgeable about whatever topic we discussed. Let me put it this wayI've moved a couple times within the last 3 years, so I'm not as close distance-wise to his office, but I decided not to change my PCP to a doctor who might be closer by because that's how much I value the work and care that Dr. Nienaber provides.

The best experience I've ever had at a doctor's office. Outstanding customer service and the doctor actually listened to my priorities and concerns for the first time ever at a doctor's office.
