Lizzie - HVS Mascot

Lizzie has been here at HVS since it's opening in 2012. She spends much of her time behind the receptionist counter when she is not out playing in the yard or at home with Dr. Ruisi. Lizzie was found abandoned in the desert shortly after being born. Fortunately, she  was found by a good Samaritan who immediately brought her in to Dr. Ruisi for care. The rest is history!

Cris has been in Wickenburg for three years and has lived most of her life in Arizona. The majority of her childhood  was spent in Cave Creek where she was surrounded by horses, dogs, cats, chickens, goats, and a variety of other critters. She has obtained degrees from Phoenix College and The University of Arizona.

Cris currently lives with a dog named Chevy and enjoys cross stitch, reading, watching movies, and going on road trips with her mother.

After retiring from a 22 year job, Maureen has enjoyed the opportunity to learn something new. She has been working and volunteering at HVS with her daughter, Dr. Ruisi. It is challenging, but she loves it!
