Dr. Singh then worked as an Assistant Professor of Immunology at his alma mater for two years, and practiced small animal medicine part-time. In 1994, he came to the United States to pursue a PhD in Veterinary and Medical Entomology at Oklahoma State University.
His studies focused on the immune mechanisms and effect of transmission of various diseases by insects and ticks to vertebrate hosts, with the focus on Lyme disease.
After finishing his doctoral program in 1997, Dr. Singh worked in academic research at the University of Georgia, the University of Arkansas, and the Centers for Disease Control in Fort Collins, Colorado. In 2004 he resumed working as a small animal practitioner in Denver, Colorado (2004-2006) and then in Santa Rosa, California (2006-2010). Dr. Singh is the owner and Medical Director of the American Canyon Veterinary Hospital. Dr. Singh’s practice philosophy places major emphasis on prevention and early detection of disease processes. He lives in American Canyon with his wife Katya.
Recently relocating to Fairfield, Dr. Sparks is excited to become part of the American Canyon Veterinary Hospital team. In her spare time, she gardens and cares for her menagerie, which includes an elderly (22 year old) leopard gecko, a bearded dragon, and her shelter rescues: a green iguana and an adorable Chihuahua mix named Morris. When the animals permit it, she enjoys hiking and bike riding, and as many trips to Yosemite as possible with her husband Jay.
Over the years, Julie gained experience in general practice, emergency medicine, as well as specialty (reproductive) medicine. She worked as a Receptionist, Technician, Supervisor, and is now our Practice Manager.
Julie has been with our hospital since the day we opened, and was originally our Senior Veterinary Technician as well as our Practice Manager. Over the years her passion for this practice has lead to a stronger passion for veterinary practice management so she has decided to further her career and is currently taking classes to become a Certified Veterinary Practice Manager.
Outside of work she enjoys spending time with her family and her dogs. She has a 7 year old daughter and one baby on the way. She has 3 German Shorthaired Pointers, a rescue Pit Bull, an old Shih Tzu and two cats! Julie and her wife also have Allentown Kennels in which they breed their pointers as well as show them.
In her spare time Catherine loves to be outdoors whether at the beach, hiking, or enjoying an outdoor concert. Her other passion in life is travel, both nationally and internationally. Thanks to Semester at Sea, a study abroad program, she was able to experience multiple countries throughout Asia and Africa, and more recently completed a backpacking trip across Europe. Travel aside she loves snuggling up on the couch with her two dogs Roscoe, Golden retriever, and Milo, terrier mix, and occasionally her cat, Rosie.
