Concord, CA real estate agents who do some investing?

[Chi Wen]

Hi - i'm now mainly looking at Concord, CA (and some areas in Sacramento) for a house/duplex but even using the tool here and searching the forums I couldn't find any. Using zillow agent finder shows a lot in Concord but hard to tell whether any of them are "investor-friendly" or do any themselves. 

Does anyone have any recommendations for agents or (is it better to find someone investor-friendly but not specialized in Concord area or find a Concord agent familiar with the areas but don't invest themselves?)

thanks
