When it comes to time management, he is the best. My kids hardly have to wait, we are in & out in 30 min. It's amazing.
However, the trade-off to this is that he doesn't really make the
effort of making small talk with the kids to make them feel at ease. Same goes with his staff, they are all so quiet. They don't really make kids feel comfortable.
Dr. Hollenberg knows what he is doing but my kids aren't too thrilled going to his office. He & his staff can sure use a little more fun now & then.
