I had a great experience at Portland Smiles. Everyone was very helpful and accommodating. Daija and Katie were great with helping me schedule my appointments and set up a payment plan. Emma my hygienist was amazing, very informative and put me at ease. I would definitely recommend this office to anyone who has anxiety about to the dentist, or who is just looking for a great team who cares about their patients.
