“On Halloween in 2014 there was an unfortunate accident with both of my horses in our pasture and both were killed. My husband was out of town for work and I had no one to help.

We live close to Environmental Construction Services and we have known their family for several years. So I went to ask them for help and, even though they were let off early, Daniel, Jimmy, and Richard came to my pasture with their equipment to help me bury my poor horses.

Words cannot express my gratitude for finding such warm and kind hearts on that sad day. These are real family people and I am glad to know and do business with them.
