Harris County Constable Precinct One Constable Alan Rosen partnered with the American Red Cross to extend the opening of the warming center, located at Pleasant Grove Missionary Baptist Church, 2801 Conti Street, Houston, Texas 77020. The warming center was a place of respite for the homeless and others who needed relief from the frigid temperatures. Constable Rosen says it is important to him that we help those who may not be able to help themselves.
