Looking for a medical office space

[Woojin Joo]

I'm looking for an office space to sublease/lease in Los Angeles for a medical practice.

Do people typically use agents for these types of searches? I noticed that it's much harder to get in touch with an agent than it is with residential real estate.

I got a lot of help from BiggerPockets while I was searching for the house I currently live in, so I thought I'd try asking here.

Anyone know of agents in Los Angeles that can help me find a medical office space? 

Or anyone with experience that wouldn't mind answer a couple questions about the search?
