  • Amber
    Veterinary Assistant/Technician

    'I'm Amber and I am one of the Veterinary Assistants. I step in with the Technician's whenever needed. Of course I am working in the veterinary field because of my love for animals, but I also find all aspects of the medical field fascinating.

     My mother is a retired Emergency Room Nurse and she is the reason I became interested in medicine. Unfortunately, I am squeamish with any medical treatments involving humans; maybe not so unfortunate as I truly love the field of Veterinary Medicine. I attended PMI and received my Veterinary Assistant Certificate in 2016.

     I have been a part of the Duval family since February 2016 with a leave of absence from 2017 until I came back in May 2018. I could not imagine working with a better team of support staff and Doctor's!.'

    Amber shares her home with her Husky, Niko and two domestic short hair cats, Oliver and Kody.

  • Kayla
    Practice Manager/ Technician

    Kayla was born in Dallas, TX and moved to Greensboro, NC as a small child where she grew up and obtained her BS in Business Administration at the University of North Carolina at Greensboro in 2014. Kayla spent her college years working in retail as a sales associate where she quickly became an assistant manager.

    In January 2016 she relocated to Arizona to be closer to her family and to ultimately pursue her life long dream of becoming involved in the veterinary field. Kayla started at Duval Animal Hospital as a Veterinary Assistant and has worked her way up to Veterinary Technician and now Practice Manager.

    In her free time she enjoys grilling, spending time with friends and family and being outdoors.

    Kayla currently shares her home with her 8 year old Cavalier King Charles Spaniel, 'The Boog Man', a year old Cattle Dog Mix, Angus, and her 2 year old cat, Baby Ennis.

    Kayla is very excited to be using her back ground in business and experience in the veterinary field to continue to make a difference in the lives of companion animals and their owners.
