Dr. Lieu’s Biography
Dr. Lieu was a Willamette Dental patient in middle school and remembers how much he admired the dentists who cared for his teeth. A few years later he had the opportunity to shadow a neighbor who worked at the practice, and he saw firsthand the compassion providers felt for their patients. Those experiences combined with the company’s philosophy inspired his decision to become a dentist and join the practice. He likes to begin his days with a cup of coffee, and take a few moments to be appreciative and mindful.
When he’s not behind the chair, he enjoys time with his dog and close family. A Portland native, Dr. Lieu attended Clackamas High, Oregon State, and OHSU.

Great experience
Nov 17, 2025
The appointment was perfect!
Nov 14, 2025
The dentist was rude and condescending
Nov 14, 2025
The girl that did my x ray was great. Dr Lieu was not empathetic and he was rude and callous. Not a dentist I ever want to see again. When someone is in pain try to be more considerate. He seemed to be irritated I couldn't bite down and he showed me his perfect bite. I'm missing teeth I don't have a perfect bite.

Thank you for your service.

The visit was pleasant and fast. My son really had a good time.
Nov 3, 2025
It takes forever to get an appointment with you folks!!! And some employees there are very unprofessional or have been.
Nov 2, 2025
I had a horrible experience. I've never felt so ashamed or so belittled at any appointment I've ever been to in my life. I was so disgusted with the way I was treated. Not to mention, they said they can't do anything about my teeth now because it's been so long. Well, that's only because that's how fast you guys could get me in.
Oct 20, 2025
Very pleased with the service
Oct 24, 2025
Thank you for your service. My kids loves coming over there, because they felt your love and kindness and the hospitality that you gave them.

Sep 28, 2025
I appreciate the appointment was on time and went faster than I expected
Sep 27, 2025
The dentist showed compassion and concern for my child's dental health.
Sep 13, 2025
They made me so comfortable especially during the time of the shot. Continued to ask if I was going good.
Sep 12, 2025
Great reception and incredible dental care!

Great customer service, they treat myself and my daughter like we are family..thank you for such wonderful support and help
Aug 29, 2025
Great job they did thank you
Aug 30, 2025
I enjoyed the people there a lot, and they helped me understand what was going on. The only downside has to be the MONTHS of wait time to get an appointment, and now I'm going to have to wait more months to be able to finish getting help with cavities.
Aug 28, 2025
I have been a patient at Willamette dental 2006 and I have never had a bad experience. Thank you!!!
Aug 23, 2025
Dentist barely looked at my tooth
Aug 22, 2025

Thanks to the nurses and doctors who treated me kindly.
Aug 11, 2025
I've been going here to Willamette denta
Aug 2, 2025
This was the first time I have ever had a positive experience getting a filling. They were so quick and the whole thing was painless
Aug 1, 2025
The dental assistant we worked with that day was phenomenal. She was so kind and showed a lot of love for her work. She worked very well with my son who has special needs. The dentist was also very professional and kind.
Aug 1, 2025
You do your job very well.. I love to bring back my kids here..
Jul 30, 2025
My dentist was very rude. He would not listen to me. He talked over me. He made me feel guilty that the fact that my cavities had spread, he didn't listen to the fact that I had other medical issues that happened in the prior years had been there. It was the worst experience I've had in decades. He's a horrible dentist. I don't know what his problem was. Even the nurse felt some kind of way after he left the room. Someone should talk to him.
Jul 26, 2025
Very good, friendly
Jul 23, 2025
My visit was good, was in and out in a timely manner.
Jul 21, 2025
My appointment time was a month out. That's the only discomfort that I experienced.
Jul 20, 2025
When a person has a appointment make sure they call way ahead time to cancel so I wouldn't have to drive to the office for nothing
Jul 19, 2025
I slept all the way through it
Jul 19, 2025
They where easy to talk.
Jul 19, 2025
Receptionist are kind.
Jul 19, 2025
So far it's ok
Jul 17, 2025

Jul 17, 2025
Wonder people took great care of me
Jul 5, 2025
Dentist had a smug and arrogant attitude. I feel my family is treated differently than others at every visit.
Jun 27, 2025
The staff there are very nice and helpful. They listened to my concerns about my grandson's dental needs. They were all very professional. Thank you

Jun 21, 2025
They were very great, appreciate everything they've done for me. She explained everything about my mouth and my teeth and my deep pocket and stuff. So I recommend my family and friends to go there, but they don't have no open for them. So thank you.
Jun 15, 2025
I wish I had asked to see the X-ray, I'm wondering how an infection would look. The teem I had was a 10 !! They made my day. Specially the technician !!!! Her calming presence REALLY helped me be relaxed.
Jun 18, 2025
The hygienist was great...very polite and informative of what I could do to help my gums. I had a pleasant experience.
Jun 11, 2025
The only downside is how long it takes to get an appointment. Everything else is great
Jun 8, 2025
The dentist and assistant did a great job!

May 31, 2025
The staff was absolutely excellent, very knowledgeable, very, very friendly, in a great mood. The doctor was very, very good. The procedure was painless. Later in the evening, I did not have any pain or anything. Thank you very, very much. It was a very good experience. Definitely have already told other family members and friends. Goodbye.
May 31, 2025
The staff and technicians have a perfect balance of professionalism and friendliness!
May 22, 2025
Nice reception people and great work by hygienist and evaluation and recommendation by dentist.

Apr 24, 2025
Everyone at Willamette dental is very professional and helpful.thank you for everything.
Apr 21, 2025
I did not see Brian Lieu, I saw a female assistant that did a good job resolving my issue
Apr 19, 2025
Scheduling was super easy, the staff were great at check in and the hygienist was amazing and patient and kind. The dentist however felt like he stomped in barely looked in my child's mouth and had a really "I don't care to be here" attitude. The hygienist was more helpful than he was. I def don't ever want him to see any of my kids or me.
Apr 19, 2025
Everyone was very helpful
Apr 17, 2025
Am very happy with the work that provided for me thank you so much.
Apr 4, 2025

Mar 31, 2025
Everyone was/is super cool and accommodating!
Mar 29, 2025

Mar 29, 2025
The staff was very polite and helpful.
Mar 28, 2025
I absolutely love the staff here. Always friendly, polite, fun, informative and best ever!
Mar 21, 2025
I wish that they had told me the results of my x-rays. Did I have any decay? I forgot to ask, but it was up to Dr. Lieu to let me know. Other than that, I'm happy with my appt.
Mar 21, 2025
Just one thing nit sure if always like this but did you do like appointment reminders. I never got one . Just wondering. Other then that really helpfully crews.
Mar 21, 2025
The staff are amazing. The appt lead times are insane. Also I waiting 25 min on the phone just to make an appointment. Got to be throwing away clients.
Mar 5, 2025
The dental hygienist/assistant was amazing and gentle with my son and also her conversation with me through the appointment was so pleasant and welcoming. Sometimes dental appointments can be filled of all the things you as a parent know that can be better but sometimes it's the delivery that can change the impact of the information delivered. The dental assistant was amazing! The dentist was great too. We never know what parents or people are dealing with so we have to treat people with kindness.
Mar 2, 2025
Actually enjoyed this trip, very satisfied
Feb 24, 2025
Well, I'm a dental group is pretty professional, pretty comprehensive, very great system. The only thing that I didn't like was the doctor. He seemed a little impatient and I kind of wanted to speak to him a little bit more about my specific teeth and things I wanted to do. But other than that, the hygienist was amazing. The person before her work was amazing. Everything was amazing, but the doctor seemed a little impatient. That's all. Thank you.
Feb 24, 2025
I am thankful
Feb 19, 2025
They care about my dental health and very punctual and professional
Feb 11, 2025
Great customer service, they take extra care and time to give the care needed for my daughter. I love how all staff and dental assistance were patience with my daughter. Thank you for such your service
Feb 10, 2025
Super helpful and friendly. I've been going to them for about 10 years and are always helpful and friendly.
Feb 9, 2025
Have the providers tell clients what there going to do before using tools and hands forcible so clients won't fill uncomfortable
Feb 9, 2025
Honestly, my experience with that specific dentist at your clinic was horrible. He looked and spoke to me like I was trash and made me feel very uncomfortable and I honestly will be requesting to never have him again. Other than that, my experience with Willamette has been great, but that dentist needs to learn how to treat people because he was super disrespectful and just rude. He really needs to fix his face to say the least. So that's all I have to say about that dentist.
Feb 9, 2025
Staff is always pleasant and helpful! We appreciate the dental team so much. It would be great if I could schedule appointments at the office, having to remember to call is very inconvenient and really my only complaint. Thank you!
Feb 7, 2025
It is no longer easy to get appointments with them in a timely manner. I really wish that they hadn't closed the dental office on Welder. The dental office where I have to go now is so far away from where I live.
Feb 2, 2025
It was quick, smooth, well executed and fast.
Feb 1, 2025
I can't remember her name. She did amazing job on my teeth. I thank you all.
Feb 1, 2025
The dentist that I saw was very nice, he was kind, he knew what he was doing and talking about and I appreciate that.
Jan 30, 2025
I am very happy with your services. Thank you very much.
Jan 20, 2025
Because of someone not having the experience of doing impressions I had to leave work in the middle of my day. It is a 45min drive for me just to get there. I still don't have my bottom dentures, no phone call either to let me know when I can pick up dentures
Jan 21, 2025
Best dentist office I ever been too
Jan 17, 2025
Wait time was a bit long.
Jan 12, 2025
everything is great. My son was satisfied after the reception! Thank you.
Jan 11, 2025
Everybody was very professional, friendly and the kicked backed, easy going atmosphere made it a very pleasurable visit. And I'm looking forward to my next appointment thank you.
Jan 11, 2025
I really appreciated Valerie's professionalism and friendliness. All the staff were great. Dr. Lieu was very knowledgeable and helpful.
Jan 11, 2025
Thanks for taking care of my teeth you rock.
Jan 11, 2025
Providers were misleading and the hygienist as well as the dentist were not in good moods, and therefore were not very friendly.
Jan 4, 2025
much. Everyone is professional and great. We just wish that when multiple appointments were needed that we could make them together or closer together rather than waiting months out between appointments. Other than that, we absolutely love it. It's great. Thank you.
Dec 29, 2024
The fill-in dentist had a bad attitude. I needed a bad tooth pulled and he barley looked at it. The assistant was good and helped me get a sooner appointment than I had already. So I can still use both appointments.
Dec 29, 2024
My request to have all the options written down so I can understand them was ignored.
Dec 27, 2024
All my expectations were met and despite me having many questions, which I wasn't able to ask all them, I was overall pleased with the professionalism of staff!
Dec 26, 2024
The hygienist who assisted me was very professional and had excellent "bedside manner" as she talked through what all was happening. It took several attempts to get my tooth sufficiently numb and she was quite patient with that process. The dentist who did the work seemed a bit impatient with the process and seemed frustrated that my tooth wouldn't numb. He had an alternative dentist come to numb it and that person was also very informative and had good "bedside manner" in assuring me that it wasn't my fault and talking through the process. All in all, I believe the problem was fixed, and the primary dentist who did the work did a satisfactory job with the tooth, which is my primary concern.
Dec 20, 2024
As an incentive, I got the gift card. That's only one problem when you're giving that gift card. We should be able to use it anywhere not just on Amazon. I have never shopped on Amazon. And really would prefer not to. So I think that should be noted when you're offering that kind of card.
Dec 19, 2024
Very smooth visit. The DA went over everything with my little one so she was not scared. Dr Lieu was very kind.
Dec 17, 2024
They really give you the attention you need, thank you.
