At Mill Creek Veterinary Hospital, we want our pet care to have a personal touch. Get to know your veterinarian’s here before your next visit!

Charles “Bill” Acock
Doctor of Veterinary Medicine (Medical Director)

Doctor Charles “Bill” Acock has been practicing veterinary medicine for over 40 years. Bill obtained his degree at Washington State University, class of 1982. Dr. Acock understands veterinary care can be expensive and works with his clients to create the best plan for their budget, and their pet. Bill enjoys working with both large and small animals, and strongly values educating owners, staff, and new veterinary doctors. Bill and his wife have 3 grown children and they enjoy spending time on the Oregon coast.

Cassandra Van Atta
Doctor of Veterinary Medicine

We are so excited to have Dr. Cassandra Van Atta as our associate veterinarian here at Mill Creek Vet. Dr. Cassandra is not new to Washington as a graduate from Washington State University, but she originally hails from Oregon. She is very passionate about large animal medicine and loves using her knowledge to provide the best care and treatment in a mixed practice. She excels in surgery and diagnostic ultrasounds. When not at the hospital, she spends time with her two dogs Ember and Flame, and can be found tending to her plants or welding. 

Cheree Bates
Hospital Manager

Cheree Bates has been with Mill Creek Vet since 2004 and considers the clinic her second home. Active in all roles at the practice, she provides an incredible amount of knowledge and care to clients and patients. Cheree participated in the Walla Walla Community College Nursing program but has since transferred her skillset to furry companions. When not at the clinic, you can find Cheree attending concerts, enjoying the outdoors, or reading a book.

Crystal VanDyke

Crystal Van Dyke is our rockstar receptionist at MCVH!  She has been with the practice since 2009 and greets everyone with a smile. She loves creating a personal experience for each client, and her consistency and professionalism is unmatched. After moving around when younger, Crystal has found herself at home in Walla Walla for many years. Crystal enjoys spending time with her family, watching movies, and shopping.

Claire Engan
Licensed Veterinary Technician

Claire Engan is a licensed veterinary technician and has been working in the animal care field since 2014. With a passion for shelter medicine and exotics, she brings her knowledge to Mill Creek and loves being a member of the MCVH family. She enjoys providing comprehensive patient care, radiology and labs, and educating clients. Claire also serves her community as a realtor and enjoys playing classical music. Claire spends time with her boyfriend, and their ornery cat Zergling.

Tyler Dibelka
Veterinary Assistant

We are thrilled to have Tyler Dibelka join us – all the way from the east coast! Tyler grew up in a very small town in New York, before following his dream of working with animals to the west coast. After working with humane societies in both California and Washington, he set his sights on the medical field. Tyler is passionate about client education – and loves talking about exotic pets as well. He has two dogs at home, Gypsy and Rus, and is always trying NOT to add more animals to his flock (though it’s tempting.) Outside of work, Tyler enjoys hiking, gaming, art, and spooky movies.

Patsy Fuston
Veterinary Assistant

Patsy Fuston joins us from the other side of the border, currently living in Athena, OR. She was born and raised working with large animals, including sports like barrels and team racing. Patsy has always been a caregiver for people, and is excited to transfer her compassion and experience to the veterinary field. At home she has 3 children, two pit bulls, and even a snake! When not working she enjoys outdoor activities like fishing and hiking.
