They work well for me! Don't know bout those other reviews...
I've lived in the East Bay on and off for the last year and have had 4 assignments with Diversified, ranging from reception to inventory in a warehouse to filing in the SF financial district.
I don't have much experience, but I think they see I work hard and I feel like they really do the best to get work for me. I've learned quite a bit. I've liked some employers more than others, but never had any problem with Diversified. Very friendly, even when I've asked them to fax me a last minute time sheet.
Plus, I don't know what the previous reviewer is talking about about public trans, because I haven't driven to any of my assignments and the people at Diversified keep this on record--they go out of their way to tell me the public transit directions with out my even asking. I'm not coming from San Mateo, but they are located in Oakland, so realistically they can only cover a certain geographical distance.
I will say that my assignments have mostly been short--2 weeks max, or weekly for 8 weeks. But this is what I've wanted--I think they would accommodate temps who want more intensive work too.
Finally, most or all of their employers are non-profits or government orgs, which fits my comfort zone a bit more in terms of office culture.
4/5 stars--one star off just because I could do with assignments a little more frequently. but in this economy, I don't really blame them...
And this change of phone systems away from a 9-5 receptionist.
