I am drafting an email in which I would like to convey that
Dian Guang Zhou is there most of the time
but would like a more effecient way of conveying this idea.
I want the sentence to read like so: [Subject] [verb] [place pronoun].
I thought about frequent, but it makes the subject sound like a patron instead of an owner (and he is an owner). I wish I could say "he oftens there."
The verb frequent can work here as a single word:
Dian Guang Zhou frequents the art gallery.
Defined as
to visit often; go often to; be often in: to frequent the art galleries. (Dictionary.com #4)
Another verb that might be a little more edgy is haunt.
Dian Guang Zhou haunts the art gallery.
Defined as
to visit frequently; go to often: He haunted the galleries and bars that the artists went to. (Dictionary.com #3)
With your updated clarification, you can say He's often there of, as spagirl said, He's usually there. But this doesn't give you the verb you requested. (You can also say He often is there, but this doesn't contract nicely to He often's there, which, apart from the apostrophe, is like your preference in your question.)
