Long-time customer here and totally agree -- they are awesome on timing. I think they do this by virtue of having a system. They seem to have a systematic effort thru the entire office of abiding by schedule appt times. Some of that is systematic scheduling to prevent overbookings, etc.

I one time showed up 2min late and they sent me back home, that is when I knew they were the real deal. I'm so glad they did, because 1. I was never late again, and 2. I know they wouldn't be late for me in the future.

I think many times when doctors are late, it is often because

0. They have a cascade of latenesses with really just a single early appt that is actually late causing the domino of late starts and hence ends.

1. They have a patient come in late or w/o appt, cater to them or "squeeze them in"

One thing OMG has going for them is the generally professional clientele -- many of the clients dont want to arrive/leave later either, so that is good for everyone.
