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.

I like it because they treat me and my family well. I would recommend Agüilame because they treat patients very well. Thank you.

The previous dentist did not listen to my concerns and this time the new one did listen. So we are getting things worked on now that should have been when I brought up the concern before.
Jul 19, 2026
Thank you for an amazing first experience!
Jul 11, 2026
After coming in find out what was wrong with my tooth, unfortunately I didn't have enough time to get it repaired the same day. The worker stated that I could just call in to schedule. I had no idea it was going to be 2 months later.

Thank you ?
Jun 27, 2026
The dentist didn't explain anything to me. He just said I want to see the patient in 6 months and didn't give me any more information until I asked. He was not informative. But it was nice being seen right away
Jun 24, 2026
Everything's fine.
Jun 22, 2026
The appointment went smoothly.

I had a great experience during my crown procedure. Jose, the dental assistant, was excellent-he knows what he's doing and took his time to make sure everything was done properly. His attention to detail and professionalism made the entire process go smoothly. Dr Lieu was also very knowledgeable and made sure I was comfortable throughout the entire procedure. He took the time to explain things clearly and checked in regularly to ensure I was doing well. I really appreciated the care and attention I received from both Jose and Dr lieu. Highly recommend!

Being overbooked with short staff doesn't help any situations; each patient deserves time to make sure needs are met.
Jun 13, 2026
I have no reservations with this dentist. Everything has been 100%. I love them!
Jun 13, 2026

The physician was amazing and I love how he explains to my child what he's doing before he does anything in her mouth he's a great physician he needs a raise...
May 28, 2026
Very efficient and caring. A touch all other professionals should learn from and aspire to.
May 26, 2026
Everything's great, thank you.
May 24, 2026
The 2 people that worked in me were both professional, eased my fear of being there, and did a great job of repairs to my teeth. On the other side, I had to wait 2 MONTHS for an appointment. When I called back to make my next appointment, as I have multiple teeth that need work, I waa told that there were no appointments available, AT ALL. I would need to call back in a couple weeks to see if any one canceled. This is very hard as I am desperate for repairs.

Apr 25, 2026
Dr. Lieu is great. He gave me a clear and concise picture of my dental health. He gave me clear information about my choices with a developing issue in a filling. The assistant and hygienist were extraordinary as well. Easiest x-rays and best cleaning I've ever had.
Apr 23, 2026
Great staff! Fast and efficient.
Apr 16, 2026
Willamette Dental seems to be way overbooked. Very hard to get an appointment. Looking at going elsewhere due to having to wait for a timely appointment.

Pro-team. That office needs a pizza party for lunch on a Friday or donuts, or some catering for lunch. Great team.
Feb 19, 2026
Overall very friendly experience and very informative on what care options are available based on the assessment.
Feb 16, 2026
Maybe other locations but not this one. It's the worst location I have ever been.

Jan 18, 2026
The last two appointments I've had to wait about 50 and 25 minutes past the time of the appointment to be seen, that can be improved.
Jan 16, 2026
It was informative

Always the best experience. Thank you!
Dec 19, 2025
My last visit left me with a very positive attitude toward Willamette dental. I was guided nicely to understand the "next" steps of my procedure. All staff handled their communication with my needed dental work professionally as well as on a personal basis. I am well on the mend following the guidance from my treatment team. Thank you to all so very much from me and my family.
Dec 15, 2025
The experience was mostly positive. I just wish I had been asked. I didn't think of it at the time. I was kind of out of it if I wanted to, you know, keep the tooth. I didn't think about it until later. But that's, you know, kind of the only thing. Thank you.
Dec 12, 2025
Dr. Lieu is magic he helped me overcome my fear of the dental office by being honest and straight forward and I would recommend him for everyone . he was great and so was his assistants. 10-10
Dec 11, 2025

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.
Nov 8, 2025
Thank you for your service.
Nov 7, 2025
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.
Oct 12, 2025

Sep 29, 2025
I had my daughter with me and they engaged with her as well and made everything go so smoothly
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!!!
