Caring. Driven. Talented. The team at Arrow Dog & Cat Hospital believes in a simple idea: giving every single pet who walks through our doors the kind of care we would want for any family member.

Nichole Weinstein

DVM, Medical Director

A California native, Dr. Nichole Weinstein graduated with her pre-veterinary degree from Cal Poly, Pomona, California. She then went on to complete and obtain her Doctorate in Veterinary Medicine at the University of the Philippines. She obtained her license to practice in the US at Iowa State University in Ames, Iowa. She then went on to complete an internship in emergency medicine at the Pet Emergency and Specialty Center in La Mesa, CA and has been practicing small animal medicine since 2005 in southern California.

Dr. Weinstein grew up in the outdoors riding horses and comes from a long line of cat “collectors”. She has treated dogs and cats since 2005 and has always had a special interest in emergency medicine and surgery as well as feline medicine. She enjoys being able to practice in a species-parity environment where cats have equal importance to dogs, something lacking in most veterinary practices. Outside of her veterinary practice, Dr. Weinstein is very active in her community. She organized and chaired a large breast cancer fundraiser and serves the homeless on Skid Row. She is also a mom of 2 children, 4 dogs, a cat and some fish.

San Antonio College in Walnut, California for the Registered Veterinary Technician program.

She brings with her the latest cutting-edge medicine and positive enthusiasm for the profession.
