Dr. Angela Smith - DVM

Dr. Angela Smith holds a BS degree in Animal Science from Purdue University and a DVM from Mississippi State University College of Veterinary Medicine.

She practiced for five years in the Chicago suburbs before moving to California and joining Petaluma Veterinary Hospital in 2001. After working with Dr. T. for 15 years, she purchased the practice in April, 2016.

Dr. Smith believes strongly in animal rescue. All her dogs have been rescues, and they have taught her a lot about behavior. Pain management and animal behavior are two of her special interests.

She is trained in low-stress animal handling techniques and passes this on to her staff. These techniques lead to a calmer environment when your pet visits our hospital. The result is fewer anxiety triggers and a better experience for everyone - pet, owner, and staff.

Dr. Smith lives in Petaluma with Hope, her rescue Pit Bull, and Guiness her weiner dog.

Dr. Kristensen was raised in Los Altos, CA. She earned a BA in Business Economics from Westmont College in Santa Barbara. Then a Bachelor of Veterinary Science degree from the University of Liverpool in the UK. She says "this was a great adventure and very hard work”.

After vet school Dr. Kristensen worked in Northern Ireland in a mixed animal practice, then an internship at the University of Cambridge Veterinary School where she gained “great experience and happy memories” doing overnight intensive-care hospital coverage while also supervising final year vet students.

After a stint at another mixed animal practice in Ireland, Dr. K returned to California to complete her American Veterinary Competency Exam and the California Veterinary State Board Exam. After nine years in San Jose and Los Altos working with dogs and cats, she joined the Petaluma Veterinary Hospital.
