Katy Carleton

Hospital Administrator

As the daughter of an Air Force officer, Katy grew up all over the globe, from Germany to Okinawa. Through all the changes, including attending four high schools, the countless stray pets her family adopted remained a comforting constant. As a teenager, she worked and volunteered for various organizations in the field of veterinary medicine and developed a passion for working with animals and alongside anybody who felt the same. She went on to earn a bachelor of science in animal husbandry with an emphasis in companion and captive animals.

Following several years of working in private and academia settings of veterinary medicine, she inadvertently landed in “human” health care. After receiving her master degree in health administration, she completed an administrative internship at a large multi-specialty practice where she later became developer and director of the organization’s compliance program. In May 2014, Katy happily returned to a career in veterinary medicine and became VERC’s first hospital administrator. She enjoys living in Hawaii with her dogs, Pippa and Riley.

His work ethic, leadership skills and attention to detail have always landed him in leadership roles within whatever organization he has been a part of.

He is the go-to man whenever there is a problem, and his input and oversight are important in many of VERC’s daily operations including human resources, marketing, communications, equipment maintenance, and handling client questions and concerns. Chris is very happy to be here in Hawaii with his husband, Dr. Coleman. He is an essential member of the team here at VERC and we are lucky to have him.

Christina Leval


Born on Maui and raised on the tiny island of Lanai, Christina has always had a love for animals. She was just five years old when she told her mom she wanted to be a "vetawarian." Her love for animals continued to flourish as she got older. Christina was constantly finding strays and bringing them home, nurturing them, and eventually finding them homes. She always knew she wanted to work with animals and has focused on achieving that goal. After graduating from Lanai High school, Christina moved off of her little island to Oahu and immediately sought out a job working with animals. After about a month she met someone who had been working at a veterinary hospital on the windward side. Because of her eagerness and pleasant personality she was hired almost immediately. It was then that her love for working in the veterinary field began. She has since joined the team at VERC as our evening receptionist. Christina has been working in the veterinary field for the past 10 years and can't see herself doing anything else.
