In this work we investigate the surroundings of LBVs in M33 using images from the NOAO Local Group Survey. PSF photometry has been performed in all filters and color-magnitude and color-color diagrams were produced for the full data set. We present a closer look on the known LBVs in M33 which are Var B, Var C, Var 2 and Var 83. Presented is an analysis of their stellar and gaseous environment in order to examine the possible connection to nearby associations. This is tried among other things by estimating the distance the star could have travelled since its formation. The motivaton for this is to investigate whether massive stars are built in associations with other maybe also massive stars or if they form as single stars.
