Dr. Berschauer is a long time resident of Southern California. Having moved to California from the East Coast shortly prior to high school, Dr. Berschauer developed an interest in veterinary medicine working at hospitals in the South Orange County area since the age of 15. Throughout his undergraduate education at the University of California, Irvine, he worked emergency shifts as a veterinary technician. He has maintained a passion for emergency medicine since that time.
In 1997, Dr. Berschauer received his doctorate in veterinary medicine from the University of California Davis School of Veterinary Medicine. Following graduation, he initially spent time working locally at a private practice in San Clemente with some occasional relief shifts at Animal Urgent Care and has been a full time doctor with us ever since.
Dr. Berschauer maintains strong interest in emergency medicine and critical care and has been a member of the veterinary Emergency and Critical Care Association since 1999. He has continued to attend many conferences and continuing education opportunities in emergency and critical care and always strives to give the best care to his patients.

Early on, David was drawn to the sciences and went on to attend the University of California Santa Barbara, obtaining a Bachelor's Science degree in Biology. His passion for medicine and love for animals led him to the University of California at Davis, School of Veterinary Medicine where he graduated in 2008.
After completing a rotating internship in internal medicine, radiology, oncology, and soft tissue and orthopedic surgery, he moved back to Orange County to practice veterinary medicine at a multi-specialty hospital.
During veterinary school he was active in clinical research and co-authored two research manuscripts on aspiration pneumonia, published in the Journal of the American Veterinary Medical Association. Broad veterinary interests attracted him to the advanced fields of emergency and critical care medicine, which he finds both challenging and rewarding.
David has lived most of his life in Southern California. In his spare time he enjoys being with family, friends, his five cats (he swears most of them belong to his wife), and actively participates in sports including kayaking and snowboarding.
