I live out of state, and it can be difficult to get multiple appointments on the same day. Dr. Niebauer was willing to accommodate my other appointments so I only had to come to Cleveland once. I really appreciate that.

Reviewed on Sep 21, 2021

When I mentioned that my pacemaker didn't seem to keep up with my activity, Dr. Niebauer got me in to see a device technician immediately even though I had already had my device checkup. The changes the technician made have helped my work longer and harder without feeling tired. This is a big improvement that I didn't think was possible. Many thanks!

Reviewed on Sep 21, 2021

The doctor advised me he had 12 patients to see besides me that day. This was in response to me asking him when he would review my ekg that showed SVT, he stated he would review it later and that it wouldn't make a difference in his recommendations. I thought the physician would have done review before my visit since the records were requested to be there for their review. I also don't need to be reminded that the physician is busy and has other patients to see.

Dr. Niebauer's manner is somewhat brusk, but he knows his stuff, which is what matters most.

Reviewed on Sep 10, 2021

The lady who scheduled my appointments told me I had my EKG at 8, and my actual doctor appointment at 8:15. After waiting for the dr for 1 hr and 15 mins, I was told my dr apt was at 9:30-9:45. This was a huge miscommunication and waste of my time. I had even asked for clarification when I made the apt, and it was still grossly miscommunicated.

Reviewed on Sep 10, 2021

There was a glitch in scheduling. After filling out the pre-visit questionaire, a text was sent to phone saying the appointment was cancelled. Since we had 3 appointments for that day, it prompted me to call the office. Since we live 3 hours away, we asked if we could have a later appointment for the EKG which was scheduled for 7 am. We were given a new appointment for the EKG for 8:30, which was very helpful. I asked about the Echocardiogram and was told it was not needed. EKG at 8:30 and Dr. Niebauer at 9 am. When we got to the doctor's appointment, he wanted to know where the results of the echocardiogram was. I explained we were told it wasn't needed. Dr. Niebauer said it can be done at home and results can be faxed to him, so he was sending the order to PCP Cole in Meadville, so it can be done at Meadville Medical Center. Other than that, everything was fine. I was seen timely, with very little wait time.
