I don't know if all pediatricians offices are like this, but not from what I can remember. We are in and out of his office in less than an hour for all visits.
To start off, his waiting room is almost nearly empty, or maybe 2 other families waiting to go in. The longest we've probably waited to see him is about 10 minutes. It could be because his policy is anyone later than 15 minutes *must* re-schedule so as not to create a backlog for people who are on time!
He doesn't rush or hurry you out, he spends the time he needs to with the kids and he's done!
If you need a pediatrician in Hawaii, look no further.
