Meet Your Cheney Dental Team

DR. Stacey McDonald

Dr. Stacey McDonald grew up in the small town of Entiat, WA. She graduated with her Bachelor of Biology at Central Washington University. From there, she traded the mountain life for the sunshine state of Arizona. She attended Midwestern University School of Dentistry in Glendale, Arizona, earning her Doctor of Dental Medicine degree. She enjoyed the desert lifestyle and the opportunity to improve her golf handicap, but she was eager to get back to the Northwest after four years.

Dr. McDonald enjoys all aspects of dentistry, including treatment for sleep apnea. She dedicates herself to lifelong learning through her practice. She continually works her best for her patients, as her goal is to give them the most comfortable, enjoyable experience possible.

When she’s not in the office, you can find her enjoying all the adventures the PNW has to offer. She spends her seasons outside: hiking, camping, fishing in the summer, hunting with her dad in the fall, and skiing with friends and family in the winter. She can also easily spend a rainy day binge-watching one of her favorite shows, The Office.

Our Difference

Our entire dental team is dedicated to providing our patients with the very best that modern dentistry offers. Ongoing training and education will continue to be a mainstay in our practice. It is a must in the pursuit of excellence and allows us to educate our patients for a lifetime of healthy choices and a smile they will treasure.

We are proud to be active members of our community! Our practice is committed to helping the community in any way we can. We sponsor the Cheney High School athletic program, SmileCam for Eastern Washington University, and the West Plains Little League Baseball team.
