Whitney Furr, RVT Emergency and Critical Care Supervisor

Whitney’s love for animals started in grade school when she and her childhood friend made a “vet club” where they took care of stuffed animals and bandaged them up. In 2009 Whitney decided to further this club and start a career in Veterinary Medicine. After graduating from the Veterinary Technology program at Carrington College California in January of 2011, Whitney became a licensed RVT in May of 2011. Whitney worked in General Practice for 5 years before she joined Vista in 2014 and found her true passion working in Emergency Medicine and is now the Supervisor of the Emergency Department.

In her spare time, Whitney enjoys spending time with her husband who is in the US Air Force and their 1 year old son.  They have a maltese mix named Tobie, who Whitney had rescued and fell in love with. Aside from Tobie, Whitney has helped rescue and rehome multiple dogs and cats and made sure they went to loving homes. Family and friends are important to Whitney, and she makes sure that when she’s not at work, she’s spending time with her loved ones and enjoying all that life has to offer.
