Cullum is fantastic! I run a wedding venue that needs very fast assistance when something goes wrong and Cullum is always so responsive and quick to be at our aid. They have had to troubleshoot problems that I think often threw them for a loop and they have always been so helpful and creative and willing to dig in and find a solution. Professionals who know their stuff! I would highly recommend for any type of need.
