well being of their precious babies is an absolute honor"

baby girl Olivia in November of 2009 and their baby boy Barrett in September of 2012. They

Pitbull, "Eleven" a brindle Great Dane, "Banner" a fawn English Mastiff, "Everett" a brown
tabby/white mediumhair kitty, "Nugget" a buff longhair kitty, and "Lloyd" their outside
orange tabby cat.

The family loves playing with all their fur babies, vacationing together at the beach, playing
board games and watching movies. They have a love of all things Jeep with a 1984 CJ7 and
a 2016 4-door Rubicon they take on trail rides in Missouri, Colorado and Utah.

"To say that I am happy here at McCauley is an understatement to say the least, I simply
could not live without these amazing people in my life every day."
