Meet Dr. Liz and her team...

Liz Oien, DVM, Owner

From an early age, Dr. Liz Oien knew she wanted to become a veterinarian.  Her love for the profession originated from her family farm when she would work side by side with the local farm vets.  Her education includes obtaining her Bachelor of Neuroscience Degree from Washington State University and Doctorate of Veterinary Medicine from Ross University.  Dr. Liz has been practicing small animal and emergency medicine in Western Washington since 2012.  She opened her doors of Port Orchard Animal Clinic, in 2017. It has been a labor of love and a life long dream to have her own practice. In the years since opening, she enjoys seeing the practice grow and mentoring the next generation of veterinary professionals. With her guidance many veterinary assistants have furthered their careers by pursing veterinary school or the veterinary technology nursing program.

Although Dr. Liz truly enjoys all aspects of helping dogs and cats, she has a natural affinity for soft tissue surgery and dentistry.  To make sure she stays up to date on the latest advancements, she attends national conferences and has been trained by board certified dentists and surgeons.  If your pet does require surgery, rest assured they are in skilled hands. You may also notice she has a knack for handling dogs and cats, and some say even seeing into their soul. This likely developed after years of experience and working with a wide array of farm animals while learning to adapt to the different behaviors of llamas, cows, sheep, dogs, cats and chickens. This isn’t her first rodeo, she has seen a little bit of everything.

You probably have already figured this out, but Dr. Liz is a bit of an old soul.  Her hobbies include making stained glass lamps, golf, baking, wheel thrown pottery, and listening to Frank Sinatra.  She loves to spend time with her son Winston.  Her cat Marshmallow, keeps Dr. Liz and her son company.

Dr. Mary Margaret Worley

Dr. Mary Margaret Worley, Associate Doctor

Dr. Worley earned her Bachelor of Science in Animal Science from Purdue University and her Doctor of Veterinary Medicine from Texas A&M University. She began her career as a mixed-animal general practitioner in South Texas before relocating to Washington, where she now brings her expertise to Port Orchard Animal Clinic. Her professional interests include ophthalmology, neurology, and emergency care for dogs and cats, and she occasionally extends her care to farm animals as well. Outside the clinic, Dr. Worley enjoys spending time with her cats and her Red Heeler puppy, Chili. She loves hiking and exploring the natural beauty of the Pacific Northwest.

Dr. Thea Lambert

Dr. Thea Lambert, Associate Doctor

Dr. Lambert is originally from San Jose, CA. She received her Bachelor’s of Arts degree in Biology from Lewis & Clark College in Portland, OR and her degree in veterinary medicine from UC Davis School of Veterinary Medicine. She practiced small and exotic animal medicine for 10 years in Northern California before moving to Port Orchard to be closer to family.  Her professional interests include dentistry, behavior, and internal medicine. When not reading with a cat in her lap, she can be found baking, exploring a nearby town, or finding new walking trails.

Tabbi

Tabbi, Office Manager

Tabbi knew from the start that she wanted to be surrounded by animals. She grew up thinking she wanted to be a vet but quickly fell in love with the nurturing side of being an assistant. After years of working in the field, she took time off to raise her two kids, Kailyn and Coehen, and help others raise their babies by being a nanny. As much as she loved doing that, it was only a matter of time before she found her way back into a clinic. With a history in the field, and a passion for people and animals alike, it's no wonder she ended up at such a compassionate, family-oriented place as Port Orchard Animal Clinic. When she is not at the clinic, she enjoys spending her time "getting lost" in nature. Whether it's on the lake paddle-boarding with her pup Stella, or driving down the long roads to nowhere with her husband Easton, that's where she finds her peace.

Mariah

Mariah, Veterinary Assistant

Mariah joined the Port Orchard Animal Clinic in May 2025, following her graduation from WSU with a bachelor’s degree in animal science and pre-veterinary medicine. Before pursuing veterinary school, she sought to gain practical experience, making this her first position in the veterinary field. She has thoroughly enjoyed learning what it takes to be an exceptional assistant. Mariah’s passion for animals began in her childhood, as she was often found playing outside with her rabbits, cats, and dog. Her work in veterinary medicine has reinforced the importance of patient care and diligence. She is deeply grateful for the wonderful people and animals she has had the opportunity to meet and work with over the past year. In her free time, Mariah enjoys embarking on adventures with her husband, hiking, reading, and socializing over coffee with friends.

Harun

Harun, Veterinary Assistant

Harun has had a lifelong love for animals. He graduated in May 2026 with his Bachelors of Science degree in Zoology from Washington State University. His path into veterinary medicine began with janitorial care for large animals and that exposure sparked an interest in veterinary care he has pursued ever since. At Port Orchard Animal Clinic that curiosity and eagerness to learn is shown with every patient and procedure. Outside of work he enjoys variety of interests. He winds down by playing piano, learning new snowboarding tricks, going to the gym, or playing video games with his friends.

Chloe

Chloe, Veterinary Assistant

Chloe enjoys continuing to grow her knowledge in veterinary medicine while making a meaningful difference in the lives of pets and their families. Originally from North Carolina, Chloe previously worked at a veterinary hospital before making the move to Washington and joining the Port Orchard Animal Clinic team. Outside of work, Chloe enjoys sporting events, hiking, fishing, boating, spending time at the beach, and taking walks. She is also a proud cat mom to her sweet cat, Olive.

Lisa O-Donnell

Lisa O’Donnell, Receptionist/Client Care Coordinator

Lisa has been the welcoming face of veterinary clinics for 20 years and continues to enjoy meeting new people and their pets. You might recognize her smiling face because she has resided in the Kitsap area her entire life! You will hear me say it a few times over, Lisa is a gem. She is always willing to offer a hand to anyone who needs it. Lisa and her husband, Butch, enjoy all that the Pacific Northwest has to offer - hiking, clamming, kayaking, archery, and fishing are some of their favorite activities. Not only is Lisa skilled with a bow, but she is also a trained Flamenco dancer! There is never a dull moment at Lisa’s house with her four fur-babies, Echo, Lee Lu, Frosty, and Fluffy the cat.
