Our Caring Veterinarians

Mark Acker, DVM
Veterinary School: Colorado State University

For over 25 years Dr. Acker has been serving the Wood River Valley’s veterinary needs. When Dr. Acker moved to Bellevue in 1984 to manage the Sawtooth Animal Center, he had little idea that the clinic would grow into the state-of-the-art facility that it is today. Raised in Grand Junction, Colorado, Dr. Acker attended Western State College of Colorado for his B.A. and Teaching Certificate. He also attended Colorado State University for both his B.S. and D.V.M. degrees.

Voted the Valley’s best veterinarian numerous times, Dr. Acker takes special interest in internal medicine, soft tissue surgery, as well as oncology and canine reproduction.

In his spare time, snowshoeing, skiing, hiking, fly-fishing and gardening inspire Dr. Acker to create beautiful watercolor paintings displayed throughout the clinic.

Dana Lieu, DVM

Dr. Dana Lieu was born and raised in Seattle, Washington where she attended Seattle University. She received a Bachelor of Science in Biochemistry and a Bachelor of Arts in Humanities. For the next four years she worked in the genetics laboratory at Seattle Children’s Hospital.

She has practiced in both small and mixed animal practices and has a special interest in preventative medicine, soft tissue surgery, and dentistry. When she isn’t working with patients and clients at the clinic, Dr. Lieu loves spending quality with her husband Ryan, two dogs (Skylar and Rogan) and two cats (Nugget and Nacho). They enjoy anything outdoors, especially backpacking and hiking.
