Nov 22, 2025
It took a long time and the office is way to cold to be there for 2 hours.

I had a tooth pulled and it was virtually painless and took such a short time. Everything went fast and efficiently and the team was excellent!
Nov 14, 2025
Got me in very fast and provided helpful information
Nov 10, 2025
Dr. Yoo and her assistants are very professional, kind, and explain things throughly. Extremely impressed with them. Very different from the last dental provider I had before Dr. Yoo.
Nov 8, 2025
Great experience with the dental hygienist? Not sure if that's the right title. But the guy that did the x-rays and cleaned my teeth. Just the right amount of interaction, perfesionional and personal. I also really like my Dentist.
Nov 7, 2025
The staff cared for me and my treatment and I felt comfortable with this appointment. Dr Yoo was great and wanted to treat me right away. I am glad I was able to get the right treatment and diagnosis.
Nov 8, 2025
Comfortable and friendly.

Professional, kind, caring, and courteous would be words that would describe the team at Willamette Dental Lancaster Salem office.

Oct 18, 2025
Always friendly! Love our Willamette dental
Oct 18, 2025
Dr. Yoo and Natasha made me feel heard and valued. They were very sensitive to my comfort. Dr. You seemed very intelligent and relaxed her treatment plan and the reasoning behind it in a way that made me feel confident in my care
Oct 16, 2025
I was glad to finally get my appointment scheduled, it took awhile! I will say everyone was very polite and professional!
Oct 13, 2025

Sep 13, 2025
There are very kind professional manners.
Sep 12, 2025
The reason I wasn't able to get an appointment in a timely manner is out of Willamette's control and I understand that.

Aug 14, 2025
Very professional and courteous staff.
Aug 7, 2025
When I called to make an appointment they were able to schedule me for the following week. They even called me back to reschedule an appointment for my daughter. Dr. Yoo is friendly and efficient. She is an amazing dentist.
Aug 7, 2025
The Dr. was super duper nice and polite and apologetic even though I'm the one who asked for no numbing. My only negative about anything was that there is nowhere to go on Sunday. ER's don't do dental so I waited 24 hours and there may have been a greater risk of tooth death now and what not. There needs to be somewhere to go every single day in the event of true emergencies.
Aug 4, 2025
Great crew!!!
Aug 4, 2025
Wonderful staff, everyone is very friendly and helpful.

good people. good staff. worth the drive.
Jul 13, 2025
The woman who numbed my upper two front teeth did an excellent job. That is usually very painful and her method was not. I wish I could remember her name, I'm sorry I can't.
Jul 4, 2025
We love Dr. Yoo. She's great and we enjoy going to her and Willamette it's the best ! Everyone is so nice and they all do a wonderful job. Thank you so much
Jul 3, 2025
I appreciate how quickly I got an appointment. She squeezed me in her busy schedule to do a adjustment to my lower denture. The denturest, i think that's his position, is stretched thin . I wouldn't have been able to see him for the adjustment for a month!! Which is a long time to be in pain over a simple adjustment. I really appreciate the team taking it on. Fyi you need more denturest then just one. A month out for an appointment is crazy for just an adjustment.
Jul 9, 2025
Thank you for fitting me in and checking my mouth that was giving me pain ?. I apriciate you.
Jul 6, 2025
Very pleased
Jul 4, 2025
The dental hygienist was wonderful!
Jul 2, 2025
It was fine. Never very fun to get a crown on, but it was as pleasant as possible. I did have quite a lot of pain of a few days, but I think that is normal.
Jul 1, 2025
Thank you
Jun 30, 2025
Dr. Yoo is very informative and kind to my son. The staff who assisted her are very helpful as well. They explained everything to my son before doing anything so my son is aware what is going to happen
Jun 23, 2025
The hygienist was especially thorough. Both the hygienist and dentist provided excellent information about my dental care and in response to any questions I had.
Jun 16, 2025
Dr. Yoo is the best dentist I've ever had and her staff is excellent too.
Jun 14, 2025
Your scheduling is the worst. Never appointments available when notice comes for yearly checkups. Always need to callback because person on the phone can only go out so far on the calendar. Scheduled 12 month checkup always turns into 14 or 15 month checkup. DO BETTER!
Jun 14, 2025
Dr Yoo was totally different than my earlier experience. She apologized for being rough this time.
Jun 14, 2025
I really enjoyed, not only the professionalism of the staff, but the personability. They were great to speak with and made me comfortable.
Jun 14, 2025
The dental hygienist I had was the best I've ever had. Super informational and educational while he simultaneously was doing his job. And I was just super impressed. I've never had a dental hygienist that was so educational in explaining things the way he did. So anyway, super, super impressed.
Jun 8, 2025
Wonderful team. So kinda and good with young kids, and for my appointments they were so courteous about my anxiety about being at the dentist and were so kind.
Jun 7, 2025
Mary Yoo is an awesome Dentist. The Hygienist did a great job! Very happy with my experience.
Jun 6, 2025
Dr. Yoo and her team did a wonderful job. The procedure went very smoothly. They had told me what to expect. After the procedure, they told me what to do to help my care. Everyone was so friendly, so professional. Highly, highly recommend them. I can't think of anything to improve it. It was just a terrific experience. Thank you, Dr. Yoo and your team for everything. I really appreciate all of your kind gestures and time and effort.
Jun 6, 2025
I always enjoy coming into this office.

Dr. Yoo and her hygienist were wonderful and caring.
Apr 22, 2025
I had questions answered about my dental health, that I had asked other providers many times. And the detail in which it was explained. I couldn't have asked for better care.
Apr 21, 2025
All around great clinic with amazing staff!

Great job
Apr 18, 2025
No complaints. Excellent care as always
Apr 16, 2025
Not only were my dental hygienist and Dr. Yoo incredible to work with (engaging conversations) but informative! Dr Yoo took the time to explain the anatomical structure of the jaw and connective tissues. She also spoke with me (at length) about TMJ, teeth alignment. As well as how my current aligners would be better suited for a more hands-on approach. I appreciated the enlightening conversation and the time the staff took with me.
Apr 14, 2025
My provider and my hygienist and the office staff are fantastic.
Apr 14, 2025
Dr. Yoo is great and even made time for a question about my own car and put in an order and got the panoramic pictures to be done so I could be referred to ortho. I really appreciate her going above and beyond! Fantastic service
Apr 11, 2025
Appreciated both the hygienist and the Dr giving tips on ways to use Waterpik and types of mouth guards.
Apr 9, 2025
Staff and providers were great and very attentive . Explained everything that was going to be done. Step by step and gave me options. I highly recommend coming here .

Mar 27, 2025
Everyone was very polite. The professionals talked me through what they were doing and explained why they were doing it. I felt seen and respected as a patient from beginning to end. 10/10
Mar 20, 2025
Our family has seen Dr. Yoo for dental care for 20+ years. I can't imagine receiving the high level of care that she provides from any other Dentist. That's why we stick with her and Willamette Dental. The "merging" with Delta Dental has been a bit rocky, but assuming leadership figures things out, we might possibly stick with her for another 20 years, if she doesn't retire.... ;-)
Mar 20, 2025
Keep up the good work
Mar 16, 2025
Dr. Yoo is the best dentist ever.
Mar 13, 2025
love my dentist and the staff too!!! Delta dental accounting is inept!!!

Feb 27, 2025
Dr Yoo is amazing!
Feb 24, 2025
The dental assistant really helped me because I was panicking in an anxiety moment. I didn't have much hope of actually getting help, but she pushed through every wall I put up as fast as I put it up. I am very thankful for everything.
Feb 19, 2025
The entire staff made is pleasant to visit the dentist office. My husband and I were both very pleased with our treatment there.
Feb 19, 2025
Dr. Yoo and her support staff are the best I have ever had in my entire life.
Feb 19, 2025
Yes, I saw Dr. Mary Yu. She is absolutely amazing. She is very gentle. She is quick. She has little hands and she is always so nice and just a very positive person. I just really enjoy her being my dentist.
Feb 9, 2025
Difficult to get an appointment in a timely manner.
Feb 8, 2025
We really appreciated that the doctor talked directly to our son who is 7 years old and talked to him like he was the one listening and that he was a part of the care and we just really appreciated that. Thank you.
Feb 6, 2025
Dr Yoo is always friendly and professional. She is fast and thorough she did an amazing job as always

Jan 27, 2025

Jan 24, 2025
people in the waiting room with phone speakers on blast. No respect for others in the room. There should be a policy, no cell phones in the office!!!
Jan 23, 2025
I like to thank the doctor and the assistant who helped me from the day 1 till my appointment with smile and so much kindness
Jan 19, 2025
Myself and my four kids were all seen in one morning for cleanings. Everyone from the receptionists, hygienists, dentist, and the checkout staff were so kind and warm. We had a great experience!
Jan 16, 2025
This was the best dentists vist that I have ever had. The team were incredibly attentive, never condensending, and were able to produce results that I can only describe as amazing. Thank you again to everyone at Willamette dental! You really improved my outlook on life.

Hi, my name is John and my doctor is Dr. Yoo. She is an excellent doctor. I am glad to have a dental for my provider like dental, Willamette Dental and especially Dr. Yoo. Thank you very much for what you do for me. Have a nice day. Bye bye.
Jan 11, 2025
Mary Yoo is the best dentist I've ever had. Her and her entire team are the most skilled and have uplifting personalities that each always make us feel at ease.
Jan 10, 2025
Very pleasant place
Dec 30, 2024
Friendly, professional, helpful
Dec 26, 2024
I'm so glad the Doctor could squeeze me in to relieve my pain before the holidays. I know it probably made her day way more hectic than it needed to be. Mary went above and beyond to provide great care, and I really appreciate it.
Dec 22, 2024
Dr. Yoo is so kind and caring and gentle. She really listens and is so compassion. She made sure I was comfortable and even offered me a blanket because it was so cold in the office and kept checking on me every few minutes during the appointment to make sure I was ok and see if I needed anything. She is the best Dr I have seen and this experience is completely opposite of the past experiences I have had when I first began coming to Willamette. I would recommend Dr. Yoo to anyone especially anyone with anxiety when it comes to dental work. She has been nothing but kind and understanding everytime I have met with her.
Dec 21, 2024
The best I've ever Known. I had a sore tooth. I did not get in immediately but next day can you believe it? My toothache was taken care of beautifully much less pain the next day and yes, all of my children receive dentistry there as well. Great job people
Dec 20, 2024
Dental hygienist was a little rude. He could have been more friendly and personable.
Dec 18, 2024
I love getting to see Dr Yoo. She has been my dentist for years and I love catching up with her.
Dec 16, 2024
The staff are great. They make the visit as pleasant as it can be in a dental office. Dr Yoo and her crew were awesome!

I was able to get in earlier for my exam, but I have problems with my teeth and need a follow-up appointment for filling and crown and no appointments available. I'm in pain. I need an appointment. Thank you.
Dec 13, 2024
It was fantastic!
Dec 12, 2024
You have a well organized programme. We appreciate the care and friendlyness of the staff, technicians and doctor. Thank you.
Dec 9, 2024
I have known Dr Yoo for over 20 years. She is the absolute best! I drive from Albany to Salem just to see her!
