In Loving Memory

Cauleen Goulding


Back in 2011, our firm hired an exceptional staff accountant that quickly learned and grew with us to become an integral part of our accounting team. Cauleen had a personality that was larger than life and it was a pleasure having her on our team. She loved working with people, had a wonderful work ethic, and was just an all-around kind loving person. Cauleen enjoyed traveling with her husband, riding her motorcycle, seeing the latest blockbuster film, and spending time on the river with her three dogs. Chicken phalanges (as she called them) were her favorite meal and we could always count on her to have some ramen noodles in her desk when we forgot our lunch.

On Friday, September 11th, 2020, she suddenly passed away from an unknown medical condition. Our sorrow is immeasurable and we deeply grieve her loss. Our hearts go out to her husband, Shad, her son Kazen, and her grandchildren.
