I had to wait two and a half hours for my first appointment. The staffs response was you usually have to wait to see Dr Grondel. My second appointment again 2 hours waiting. A patient in the waiting room said that he has his staff schedule appointments before he is even there while he is checking on patients in the hospital. I was not impressed with him as a Dr or his staff. I do not recommend Dr Grondel unfortunately he is not worth the wait. There are better doctors in Las Vegas to choose from. Also while you wait you will see the staff sitting and playing on their cell phones but, when you call you go straight to a recording that they are busy and will return your call at the end of the day.
