Brentwood Neighborhood Network

Hi Neighbors.  I bought my home here two years ago and have already experienced a myriad of criminal activities around my neighborhood, including an abandoned house that is being used by drug users.  Please advise if we have any current association or group of concerned residents that I might network with to better our sotuation.  Thanks.
