Wonderful. Explains everything in detail. Staff is amazing. And they’re very quick with getting you in and out. But not where you’re rushed and left without information

My last visit felt rushed, and wasn’t personal.. I was very surprised, he talked as he walked backwards out the door, this was unusual for him, hopefully this was just a bad day!
