Carol – Technician Manager

Carol has always had a passion to work with animals. She has always been around animals and they have always played a big part in her life. Her passion to help animals is important to her so she decided to go to school and become a registered veterinary technician (RVT). She graduated from Fresno State in 2001 and has been working at AV animal hospital since 2003. Her role as the supervising technician is a fulfilling job for her. The chance to be a part of the health of one of her patients and see them grow up is extremely satisfying for her. Carol is amazing with the patients and is extremely compassionate. Her favorite part of her job is animal nursing and working with an incredible surgery team. In her off time she spends time with her son taking care of their cows, horses and their entire menagerie.



YEN- Hospital Kitty

Yen came in through our doors at 6 months of age as a rescue. He stole our hearts immediately and we realized right away that this was his new home. Within the first couple of years we noticed he would bump into things which was very concerning. Dr. Nyholt examined him and referred him to an ophthalmologist. He was later diagnosed with PRA ( Progressive Retinal Atrophy ). Unfortunately Yen is completely blind today but has not lost his sense of curiosity or awareness. He has this magical way of knowing where everything is especially his food.




Patty Cakes- Hospital Kitty

Patty Cakes A.K.A Patty was found in a parking lot 4 years ago by one of our lead technicians Juli. She was hiding in a little bush meowing and Juli scooped her up and brought her in to us. The plan was for us to keep her at the hospital till she found her permanent home but within a few days she befriended another hospital kitty named Harry and we couldn’t bare to separate them. They have been best friends ever since and you can still find them sleeping next to each other.




Harold-A.K.A Harry- Hospital kitty

In May of 2009 a orange kitten showed up on our door step

and with his adorable blue eyes and Garfield-like charm, the entire staff was

able to convince Dr. Nyholt to keep him. He is the sweetest cat and will do

anything for a good petting. We all love him so much even when he decides to make

Dr. Nyholt’s chair his own throne.
