DR. ALLISON P. ONG
Dr. Allison Ong was born and raised in Honolulu, growing up in Kaimuki. Her fascination and love for animals started from a young age when a stray cockatiel, her first rescue pet, randomly crash-landed on her family’s car. This ignited a penchant for bringing home any vagrant animal she encountered, thus building a diverse rotating menagerie that spanned her developing years. She grew up with rabbits, lovebirds, cockatiels, quails, Jackson chameleons, mice, turtles, dogs, chickens, fish, and a cat.
After graduating from Kalani High School, Dr. Ong majored in Animal Science and Zoology at the University of Hawaii. Taking a break from the world of academia, Dr. Ong worked for several years at the University of Hawaii and at Tripler Army Medical Center doing research before deciding to pursue her veterinary degree at Colorado State University. After completing veterinary school, she moved to California where she received further training from professionals in Internal Medicine, Dermatology, Neurology, Cardiology, Oncology, and Surgery at VCA San Francisco Veterinary Specialists. She worked as a relief veterinarian in California and worked an additional 4 years as a general practitioner in Hawaii before becoming a part of the Hawaii Kai Veterinary Clinic family in 2016.
Dr. Ong enjoys traveling in her spare time and delights in learning about different cultures and their cuisines. Her professional interests include Dermatology, Ophthalmology, and Geriatric Care. Dr. Ong believes that all creatures need the love and support that a home can provide. She embraces this philosophy that was forged in childhood by continuing to share her home with various rescue animals – Pickles, a serious mini Australian Shepherd; Lemon Mitts, a mischievous little kitty; Monster, a cheeky lovebird; and two sweet Zebra Doves, Pig Pig and Mini Pig.
