Dr. Wittimore actually saved me from coming in for a teeth cleaning by repairing my tooth and then also doing what was required to complete the cleaning. The staff and hygienists are always very kind and knowledgeable. Dr.Whitimore has actually saved my teeth. She took a huge investment in my mouth, teeth and lifestyle so that I could finally get back on track with my teeth. She's the best in every way! Thank you.

Dr. Whitmore is excellent!!! She listens and explains everything very carefully.
Nov 6, 2025
An earlier appointment opened up and I got a text asking if I would be available, which was great. I got in about a week earlier than originally scheduled. Repairing my chipped tooth seriously only took about 20 minutes. The dentist did a fantastic job and explained the procedure clearly and what to expect going forward.

The dental crew was excellent. It just takes too long to get an appointment.
Sep 18, 2025
It was a good experience except for scheduling the appointment. Having to schedule months in advance and still not having open appointments makes it difficult.

It is as pleasant as any dental procedure could be.

We were pleasantly surprised to be able to make appointments so quickly. My dentist is going to get back to me about options for some of my treatment by the end of the week. All of this is much appreciated. My daughter has gone from having extreme anxiety related to going to the dentist (10) down to a one over the last three years. They do a great job!

Mimi and the staff were great as usual!

I have been 100% satisfied with the care I've received as the many years that I have been going to Willamette Dental. I'm going to miss their wonderful care and service to my teeth. Because I am retiring I will be getting care elsewhere.

Dr. Whittemore is always excellent. She's courteous, direct, compassionate, helpful, and superb at explaining dental concepts in lay terms

The dental hygienist or assistant is very rude. This is the second time I've tried to receive care from her, and I hope it's the last.

Having had many dentists in my 73+ years, I had always gone for annual visits , but always hated going to the dentist! It wasn't until I retired and a friend highly recommended Willamette Dental that I - for the first time in my life enjoyed my visits to the dentist! Everyone in the office is so professional and friendly. I feel o am in excellent hands with Dr. Whittemore and her well trained assistants and staff. I always learn something about how to keep my teeth healthy - even after all these years. And because of the environment and teamwork, I always leave the office feeling better than when I came in. Thank you!
