When Hurricane Irene hit in 2011, our offices were not immune to the extensive damage it caused to New York. Our Esperance office was flooded with about a foot of water and the stairs to the office were in a nearby cemetery (pictures and video below).
We eventually got everything cleaned up and renovated at our Esperance office!
