This was a visit to the ER. So some of the questions don't apply. The care and professionalism was outstanding from the entire team. I really appreciate the in-depth explanation from Dr. N. He provided very good explanation of my issue. Easy to understand and comfortable. I feel that this was more than an ER visit. Well done! Thank you.

I have always had a good experience since I've been seeing Timothy Nickolaus. He's been patient and seems to care what I have to say. We are trying different options on my knee hoping I don't have to have a replacement.
