Boo Wiesboeck

In Memoriam

With Motorcars from 2000-2012

Boo retired in the fall of 2012 after years of dedicated and enthusiastic service and helper to Motorcars’ employees and customers. In her retirement she spent her time at home, supervising her mom’s daily domestic activities and sunbathing. She provided on-going training for Toby and Luna, instructing advanced food-begging techniques and the art of the well-timed woof. Boo was an excellent companion and a lady through her years with family and co-workers. On February 5th, 2015, Boo passed gracefully from this life surrounded by her family members.
