Dr. Lisa Harrenstien founded Avian and Exotic Veterinary Care in April 2016. Dr. Harrenstien has over 30 years of experience as a veterinarian, including employment in private small animal/exotics practice, university exotics practice, postdoctoral training in zoological pathology, consultant work related to avian and exotic species, and zoo practice. She was an associate veterinarian at the Oregon Zoo for 13 years, and is a Board Certified Specialist in Zoological Medicine^TM, an ACZM Diplomate. The ACZM is the American College of Zoological Medicine, which is the veterinary specialty organization related to the care of avian/exotic companion animals, as well as free-ranging wildlife and animals in zoological facilities. Dr. Harrenstien was the first veterinarian in Oregon to achieve this specialist ranking, and remains the only private practice veterinarian in the Pacific Northwest with this status. 

Dr. Harrenstien belongs to numerous veterinary organizations, including the Portland Veterinary Medical Association and the American Veterinary Medical Association. She also recently completed a 9 year term as the treasurer of the American College of Zoological Medicine.  She has been a Fear Free Avian certified professional since 2020.

Dr. Harrenstien’s favorite patients over the years have usually been the ones that heal well from serious illnesses and still appreciate her veterinary visits, including a California sea otter named “Thelma” who needed a lung removed, a young double yellow headed Amazon parrot named “Miss Lilly” who had her upper beak bitten off by a macaw, and a Houston toad named “Ratatouille” whose face and toes healed well after a predatory attack by a rat.

Dr. Mattucks originally hails from Kansas City and went to the University of Missouri for both her undergraduate and veterinary degrees. After veterinary school, she completed a rotating small animal internship at Garden State Veterinary Specialists in New Jersey, then an avian and exotic specialty internship at The Animal Medical Center in Manhattan, New York, then a residency in avian medicine at Island Exotic Veterinary Care in Long Island, New York. She is actively working on multiple publications and preparing to become an ABVP specialist in avian medicine. Dr. Mattucks’ love of exotic species started from a young age and led to several trips to South Africa to study wildlife management and medicine. While practicing medicine, she finds joy in educating owners about the unique needs our exotic pets have to live happy lives. She hopes to one day extend her career to include actively giving back to conservation efforts around the globe. She moved here to Portland in late 2020 with her husband, dog, cat, two birds, and far too many house plants. In her free time, she is excitedly exploring all the Pacific Northwest has to offer, hiking, restoring furniture, and exercising a self-proclaimed green thumb.
