  • Hilary R
    Lead Boarding Attendant

    You may not have met our Lead Boarding Attendant Hilary. Your pet likely has. She can be been seen cleaning the hospital, answering phone calls and assisting staff with animals  

    'The comfort, happiness and safety of our guests is my priority.'

     Hilary has been caring for cats and dogs in a professional setting since 2005.  She has worked with several 501c local rescues as well as other boarding facilities. She was originally hired in 2009 under the hospital's original owner and left after several years to finish school. She rejoined the staff here at Duval in Dec 2016. 

    When she is not attending to pets here, she is with her rescue special needs family of bulldogs. Her and her husband work mainly with seniors. You might spot them around Tucson supporting local small business and events with one or more of them in tow. It's hard to miss a refurbished Radio Flyer seasonally decorated with a wrinkly little face peeking out. 

    Pictured above with Hilary is her French Bulldog Max.
