Dr. Hess, DVM

Dr Hess graduated from NAU summa cum laude with BS degrees in zoology and chemistry. He then went to UC Davis for his DVM. He practiced two years in Vacaville with his first mentor, Warren Myers, VMD. In 1982 he went full time with Peter Morse, DVM at SVH.

In 1987 he bought into SVH and then, when Dr Morse retired in 2006, he purchased the other half of the practice and the property. Dr Hess views SVH as a technologically advanced hospital with highly skilled doctors and support staff. More than the tools to practice the high quality of medicine, our compassionate, committed and professional team is the core of our being. We are extremely proud of the work we do for all the pets and their caregivers in our community.

Shelley Flowers, DVM

Dr. Shelly Flowers joined SVH in June of 1996 after graduating from UC Davis Veterinary School. She grew up in San Diego with a family that always had a variety of pets. Her interest in animals began at a very young age and was fostered by having many animal related activities in the area including a variety of nature-related classes during the summers at the Natural History Museum, visiting the Zoo, Wild Animal Park and Sea World. Her father grew up on a ranch in southeastern San Diego County and many times during the summers the family would go back and visit family friends on their ranches. Shelly attended UC Riverside and obtained a B.S. in Biology in 1991, then attended UC Davis receiving her DVM in 1996. As a veterinarian, she is there to help families keep their pets as healthy and happy as possible. It is a blessing to be with a family each step of their pet's life.

Shelly is married to Eric who loves car rides, listening to music and flying. Currently, she has two pets. Sundae was adopted from Silverado after she had been abandoned. She recently celebrated her 16th birthday. She is a feisty long hair torti cat with a tortitude! Luckily she has mellowed with age, but she will still give a good bite or kick if she is not happy about something. And then there is Gage our 3 year old Doberman who is very full of life and always into mischief. His hobbies include going for walks, enjoying car rides, chasing squirrels out of the yard, picking up couch cushions and carrying them around the house and when you are not looking eating cat toys and pulling the stuffing out of the furniture. In her free time, Shelly enjoys reading, genealogy research, gardening, and hiking.
