Dr. Neilson
Practice Manager

Dr. Neilson was born and raised in San Diego. “Cat” being her first word, Dr. Neilson’s parents knew she would work with animals before she knew herself. When she wasn’t in school, she could be found playing volleyball and working at San Diego’s Safari Park as her first job. This is where her passion for animals and conservation really took off.

After high school, Dr. Neilson set off east, attending Amherst College for her undergraduate degree. She then went to Tufts University, where she earned a master’s in science in Conservation Medicine. Massachusetts apparently was not far enough east for her, so she moved across the pond and attended the Royal (Dick) School of Veterinary Medicine at the University of Edinburgh. She graduated in 2019 with her B.V.M.S. (same as D.V.M., only British). During her time there, she participated as a student researcher for the Scottish Wildcat Action Plan, a conservation organization working to protect the remaining population of Scottish Wildcats.

Between her experience at the Safari Park and involvement in the Wildcat conservation, Dr. Neilson initially thought she would become a zoo veterinarian. Fortunately, the sweet smiles of small animals beckoned her instead. After spending a year practicing in Phoenix, Dr. Neilson returned to sunny San Diego and started at one of our sister clinics Academy Animal Hospital in August 2020. In 2022 Dr. Neilsen Joined The Pet Hospital of Tierrasanta helping out one day a week, until she finally decided to split her time between the 2 clinics evenly.

Dr. Neilson has two cats, Mobi and Jack. Mobi was born and raised in Scotland and meows with an accent. Jack is as orange as the pumpkin he was found behind as a kitten and has classic second-child syndrome (basically, he’s the baby, and he knows it.) In her free time, Dr. Neilson enjoys volleyball, glass fusing, and cosplaying. She views the San Diego Comic-Con as an Olympic sport, and her cosplay talents have been featured on multiple Comic-Con stages.
