Josie Rose

Dr. Rose joined AEVC in August 2018 as an intern/associate veterinarian. She is a native of Cleveland, Ohio, and her interest in exotic and zoological medicine has taken her across the country. Her interest in zoological medicine started in high school when she worked as an extern with the Veterinary Department at Cleveland Metroparks Zoo and continued through her undergraduate training at Ohio State University. She is a 2013 graduate of UC Davis School of Veterinary Medicine, and it was at UC Davis where she met her husband, a fellow veterinarian. Following graduation from veterinary school, she completed a small animal rotating internship at VCA Loomis Basin near Sacramento, California and then proceeded to work the following year and a half in small animal medicine in Bakersfield, California. During this time, she provided contract services for the local zoo. Following this experience, she completed two internships in zoological medicine at Cleveland Metroparks Zoo and Indianapolis Zoo. She enjoys research, and was recognized by Morris Animal Foundation for her research with black rhinos during her veterinary training. She has published two articles, and is excited to present two more topics at this year's American Association of Zoo Veterinarian's conference in Prague, Czech Republic in October. Dr. Rose enjoys veterinary problems that require "thinking outside the box" for solutions. She especially loves cases that integrate many different disciplines to achieve the best outcome for exotic patients. Dr. Rose runs half marathons and enjoys trivia competitions, historical documentaries, and visiting her many family members across the country. She is very excited to be a part of the AEVC team!

Veterinary Technicians

Lyndsey Jett, CVT

Lyndsey Jett

A native to Oregon, Lyndsey grew up in the rural outskirts of Portland where she cared for rabbits, chickens, and a box turtle. With a passion for a variety of animals, Lyndsey went to Denver to study veterinary technology and become a Certified Veterinary Technician. Lyndsey always wanted to work with exotics, so while studying to become a CVT she dedicated much of her time to volunteering with exotics at the local animal shelter and at a sanctuary with large carnivores rescued from the illegal pet trade. After graduation in 2014, Lyndsey immediately returned to the Pacific Northwest for an internship at the Point Defiance Zoo and Aquarium, followed by work at a small animal clinic with dogs and cats, then an internship at an endangered species conservation center in Florida, then a CVT position at a small animal/exotics practice. Lyndsey joined AEVC in September and is excited about all the new learning opportunities that a 100% exotics specialty practice has to offer. 

Margot Langan, CVT

Margot Langan, CVT

The origins of Margot’s veterinary career began in childhood by caring for seven cats, one turtle, and numerous goldfish. After graduating from Bel-Rea Institute of Animal Technology as a Certified Veterinary Technician, Margot returned to her Florida roots and her first CVT job in a small animal, avian and exotic clinic. While there she had the opportunity to raise a Moluccan cockatoo chick into a flourishing and beautiful bird named Cuto. Their friendship solidified Margot’s kinship with all animals, which made her time with other avian and exotics even more meaningful. Three years later, she heard the call of the ocean and sailed to many countries in distant waters. During those adventures, she learned much about other cultures, languages, and the ocean environment sparking her desire to make a difference. She returned to land and completed a degree in Geography and Resource Management. After working in the field for a few years she realized she missed the animals and thus in 2009 settled in Portland to reconnect with veterinary medicine. Since then, she has worked with small animals as a CVT and as a clinic coordinator. Margot has completed internships at the Oregon Zoo and at The Marine Mammal Center in California, where she discovered that through rescue and rehabilitation, seals, sea lions, and sea otters can also benefit from human care. Margot is honored to join the AEVC team and is enthusiastic about her return to avian and exotic medicine that supports clients in caring for their unique pets.

Christine started her vet tech program at St. Petersburg College while working at several veterinary clinics with dogs and cats. Christine moved to Portland in 2015 to escape the Florida heat, and completed her degree and certification as a veterinary technician.
