Dr. Estella’s Biography

Dr. Estella began her career as an assistant at Willamette Dental and is proud to now be a dentist to our patients. Colleagues describe her as compassionate, enthusiastic, and thoughtful. She prefers to give teeth a chance to heal themselves before placing a filling or resorting to other aggressive treatments.

Dr. Estella grew up without dental care, which resulted in considerable dental pain and a lifelong fixation on teeth and oral health. She got to experience firsthand how life-changing even one appointment can be and is passionate about helping patients overcome anxiety. She is always happy to let someone breathe, reset, and squeeze a stress ball!

On the weekend, Dr. Estella can be found hiking, walking, or running outdoors. She loves being active and enjoying the fresh air.

I have been told I have two small cavities starting and the general area. I would like to see them though. Maybe someone could send me a diagram of which two teeth have them? I've not had a cavity in a long time prior to last year. There are gaps in my teeth. Can we get those fixed so this doesn't continue to happen?

All of the people that I interact with at Willamette Dental office in Bellingham: administrative assistant that checks us in, the hygenists, the dentist, are great. Very professional, friendly, helpful, knowledgable. I would not recommend Willamette due to the fact that it is really hard to schedule appointments and we have to book far out in advance. If scheduling were easier, I would recommend Willamette.

Oct 4, 2025

I had a great experience. It was easy to make an appointment. The hygienist and the dentist were both very professional and were careful to listen to my concerns and preferences.

I asked for an emergency appointment. After a short hold, staff asked me to come right in. When I arrived, I was almost immediately taken in. The excellent dental assistant took x-rays and then got me into a treatment room. The excellent doctor then examined me and ordered a referal to the endodontist. At checkout the great staff made arrangements for the referal process and for medication. I received excellent treatment by every one of the treatment team and am grateful to the reception staff, and everyone . Thank you

Both visits with completely different people each visit the hygenist and dentist have given conflicting info about children's use of fluoride in toothpaste and whether it's good or bad to swallow some. Thought you should know.

Dr. Estella was wonderful. She listened to my husband and he was very happy with the experience. He had numerous extractions done and today, the day after, he has almost no pain at all. As he puts it, "pretty much no pain compared to before the extractions." So very happy with our dental team. They are all so very caring, from the front office to the back office. All wonderful. This is the Bellingham office.

The wonderful staff at the bellingham location were able to get me in the very next day after I called with tooth pain and a missing filling. Stacy, Dr. Estella, and the assisting hygienist (so sorry that I've forgotten her name) were so kind and patient with me. After telling them I'd had a previous painful and frustrating dental experience, they took extra steps to help me feel calm and eased my anxiety. I felt taken care of, and I am excited to make this office and team my regular dental provider going forward.

Amber, hygienist, was amazing! She has excellent bedside manner, she was patient, and thorough. She went above and beyond during my visit, and answered all of my questions. Time spent with the dentist, was too brief for me to ask questions. They were in and out. Barely spoke to me.

Aug 1, 2025

Tumwater office is such a great place to go for my dental needs. They were so professional and seem to get along. I had been going to the lacey office and I did not have a good experience . This office is pretty far from home but the experience was better.

Dr. Estella, I liked her confidence but needs to loosen up and relax when talking to patient. She had so much gear on her head I couldn't see her face, it would be nice to see the Dentist face to face. The dental hygienist was a sweetheart and was very caring, comfortable to talk to.

Feb 24, 2025

Everyone was terrific - I only wish everyone in the world had access to such care!

Feb 24, 2025

I was very impressed with how my visit went. Instead of saying that they would have to make a new bridge and charge me, they just used the bridge that fell off and popped it back in place. That meant a lot to me and showed me the honesty of the office.

Feb 8, 2025

Been a while since I was last seen and they did a great job with all my needs

Wish there were more time available for appointments.

Jan 12, 2025

95 percent of the time they call to change appointment time then call and move it back to original time. Very frustrating

Jan 12, 2025

5

Appointments are to far apart due to staffing

Jan 11, 2025

The staff in the hall, they were quite professional and helpful. They listened and they were very courteous, cordial, and they also were very good at what they did. They were also ... the dentists were very gentle and the hygienists, they were very gentle. On all, it was a very good experience. And as I have indicated before, I would recommend anyone who so desires to do dental work.

Jan 10, 2025

I have extreme anxiety around dental care and had an infected tooth and had to have it pulled. Anna the dental assistant as well as the dentist were very kind, caring and patient with me during the whole process. One of the best experiences I have had with dental care ever.

Jan 10, 2025

Very professional staff and very clean environment meaning the building and equipment and staff. Unfortunately you don't have enough dentists like many years past.

Jan 10, 2025

Jan 3, 2025

Pro - Special shoutout on the office staff - always go the extra mile to accommodate my needs. Con - Almost always very frustrating to not be able to call the office directly. Using a middleperson creates misunderstood messages and wastes time on both sides.

Jan 4, 2025

Dr. Estella was fantastic. I cannot say enough about the staff. I love Willamette Dental. If I could shout it from the hills, I would.

Jan 2, 2025

It takes me a long time to find a dentist that I am really comfortable with, so I consider myself fortunate that I have found very professional yet relaxed and personable dentists (and hygienists, assistants, and admin staff) that I have no qualms about seeing. Big thanks to Dr. Estella and the rest of the Tumwater staff for taking so much of the anxiety out of visiting the dentist.
