Meet the Bariatric Team

Ellen Plaia, Bariatric Coordinator/Dietitian at Willamette Valley Weight Loss Center

Ellen Plaia, RD, Bariatric Coordinator

Ellen, our Program Coordinator and Registered Dietitian, joined the Willamette Valley Medical Center team in 2018 to pursue her desire to work with obesity and weight management. She is a Board Certified Specialist in Obesity and Weight Management and holds a Certificate of Training in both Adult Weight Management and Obesity Interventions.

Ellen’s goal when working with patients is to make nutrition feel simple and easy instead of overwhelming and complicated. She loves helping patients find balance in healthy eating so that food can still bring joy while making lifestyle changes to lose weight.

In her spare time, Ellen spends lots of time with animals – those of her own and volunteering at the local animal shelter. She also enjoys cooking, playing board games, yoga, and doing laundry (Yep! You read it right!). We love her energy and know you will too!
