I have worked with Zev Ross on several GIS & spatial analysis projects and he does excellent work. One of the best consultants/contractors in GIS that I know.

I have worked with Zev Ross for more than 7 years on several high-profile, intense research projects, and from working with many people in the field, I can say without hesitation that Zev is one of the best GIS consultants in the business. He is an independent thinker who isn't afraid to tell clients when he thinks they are wrong. I value that honesty and respect his opinion, and his advice has no doubt improved many aspects of my research. He also has a keen eye for detail and writes clearly – both important attributes in the health GIS world. He has taken the lead on several academic papers and gotten them published in respected journals, which attests to his writing skill.

Zev's expertise in R programming expands his repertoire of spatial analytic methods considerably. Finally he’s extremely knowledgeable about environmental exposure data and how to work with these data in a way that ensures the highest possible quality. I am happy to give him my highest recommendation.

Zev is indeed fantastic - he has been my geospatial analyst on several NIH- funded projects. He knows the methods through and through, can help troubleshoot creatively, and is a lovely colleague.
