  • You are owner of a very unique dog - can you tell us about that?

    I currently have a 2 year old Kuvasz dog at home and she is the fourth of her breed that I have owned. Kuvaszok are a rare breed of livestock guardian dogs from Hungary. Unfortunately, I don't have any sheep at home for her to protect, but she is great at guarding our family.

  • What are some things you enjoy doing away from work?

    I spend many weekends watching my daughter’s field hockey tournaments. I also love to travel, cook meals to share with my family and friends, and spend as much time as I can outdoors.
