Check out what some of our happy patients are saying about us:

Isabelle H. from Portland, OR (Source: Yelp)


My family has been seeing Dr. Sievert for seven years and we are more than happy with him and his staff. I am writing this review specifically for my Invisalign experience. I just want to start and say that although I cannot compare it (this was my first and only Invisalign adventure thus far), I feel confident in sharing that it could not have been a better experience. I went in with the understanding that my Invisalign treatment would be at least nine months, however (lucky for me), Dr. Sievert had just been through a Propel presentation and asked if I would be interested in it. Propel is a method that “injures” your teeth to promote fast healing/movement. It sounded horrific at first, but then I learned that my treatment would go from nine months to two months. I was sold. I am so happy I chose the Propel route. It was quick and less painful than getting a cavity filled. The only discomfort I had was my own anxiety and nerves, but it was over pretty quickly. Then, he popped on the Invisalign trays and I was on my way to straight teeth. I will say that the only doubts I had about the whole process was in the first two weeks of getting used to how the trays felt and learning how to take them off and snap them back in. Dr. Sievert even called me the first time I had to change to my next trays to check in on me. This was a very comforting call because I was actually having a hard time putting the new tray in so I went into the office and he showed me how and had me practice until I got the hang of it. Basically, you just shove them on! I was being too tender with putting them in. With Propel, I was changing my trays every three days versus the standard two weeks. It provided a challenge for me because I never got to have a comfort period with the trays as it takes about two to three days for them to settle in. But, I was done in two months! I shared this with my girlfriend and she was very envious as she had to go into her second nine months of Invisalign refinements. I love my teeth and I highly recommend Dr. Sievert. Just remember, it’s uncomfortable at first and you may doubt your choice and think you should have just left your teeth alone, but after you’re a few trays in, you will be happy you went through with it.

Have been going here for over 2 years for a variety of procedures. Dr. Sievert and his team are kind, caring, and down to earth. The practice is very clean and quite organized, from the office management to Dr. Sievert himself – I like a meticulous dentist (and staff)!!! Dr. Sievert always takes the time to pay attention to concerns and works very, very hard to make sure you are satisfied with your dental health. This is a great family dental practice and I hope to be a patient here for a long time!

What a great team! Dr Sievert is always on time, friendly and and very thorough. He knows me as an individual, and remembers not only my oral history, but my personal one as well. The hygienist are fantastic as well! Super knowledgeable, gentle pleasant to talk to. For something as often stigmatized as going to the dentist, I couldn’t imagine a better experience!

Ash M. from Eugene, OR (Source: Yelp)


Dr. Sievert is very kind, and thorough. My new patient appointment wasn’t rushed at all. He took the time to sit down in a small room prior to the exam to talk about questions and concerns. We talked about my general anxiety (not necessarily dental anxiety) and I felt throughout my entire appointment that Dr. Sievert and his staff were very caring and considerate of that. Any treatment options were explained, and I felt comfortable with the entire process. The office itself is lovely, and has a quiet and calm atmosphere. The staff is all very sweet and genuine. This was by far the best dental office I’ve been to, and would highly recommend it.

Everyone was very kind. Katie was super sweet and created a great atmosphere for the cleaning. Both she and Dr. Sievert were very helpful and answered all my questions in a way that was clear and understandable. The cleaning was pain free and the exam was very informative. Overall a great dental experience.

Everyone at Westlake Family Dentistry is welcoming and easy to to work with! Our entire family goes to to see Dr. Seivert, and we actually look forward to our appointments (how many people really look forward to their dentist appointment?!)! Our The staff is incredibly helpful with making appointments and answering insurance questions and always with a smile!

I recently went to Westlake Family Dentistry to have an exam and cleaning done. Everyone was extremely warm, friendly, and professional, and my chompers felt amazing after my cleaning! I even got a coupon for a free custom whitening kit. Huge thanks to Alexa, Sandi, Brianna, and Dr. Sievert. I’ll definitely be recommending Westlake Family Dentistry to my friends and family!

Care is always excellent at Westlake Family Dentistry. Check-in and check-out are friendly and quick and, during COVID, all appropriate precautions are being taken. My hygienist, Sabrina, is friendly, timely, informative, and makes the whole process easy and as pleasant as one could hope for. Dr. Sievert is knowledgeable, shares information in a way that is easy to understand, and helps the patient to make the decision that is best for their dental care. I highly recommend this practice to anyone in need of dental care.

Extremely friendly team of caregivers that are easy to talk to and honestly make going to the dentist enjoyable. They are gentle and pay extra attention to making sure you are comfortable and informed of what they are doing. Dr. Sievert, and the Westlake team, are passionate about their work and their patients…it shows in everything they do!!!

My doctor recommended that I see Dr. Seivert for an oral appliance after I visited several other dentists. Dr. Sievert is very, very knowledgeable about sleep apnea and the treatment options for people like me who couldn’t tolerate CPAP. Treatment options and the benefits/drawbacks of each were explained to me very thoroughly; my insurance information for out of pocket costs were detailed very clearly; and, the staff is all excellent. I felt like I had been a patient there for years on my one visit. I would highly recommend you start with Westlake Family Dentistry if you need an oral appliance and not waste multiple trips to other dentists like I did before I found them!

This was a great experience for me and my family. Dr. Sievert and his team are very patient and take the time to fully describe what is the current status of your teeth, any action plans that are necessary as well as described the cost and how things are billed. Thank you Westlake Family Dentistry team. PS, TJ loves being in the “No Cavity” club!

I am a new patient at West Lake Denistry and very much appreciate the excellent dental work provided by Dr. Sievert and his friendly staff. Sabrina did a great job cleaning my teeth and pointing out problem areas. Additionally she gave me a shot for dental work to follow which was pain free! I highly recommend this competent and personable team!

Westlake Family Dentistry really is a family business. The entire staff greets you with a smile, remembers your name, and discusses your overall health. I have never been to a dentist that asks me about my general health as well. Dr. Sievert mentioned a mole on my head my first visist, and asked that I have it “checked out”. After doing so, I learned that I had several moles needing to be removed, including the one he mentioned to me that I hadn’t even thought about. I had pre-cancerous moles in various locations and never would have gone to see someone because I have always had moles. This is just one example of how they go above and beyond. If you are looking for a dental office that will exceed your expectations, look no further!

After 20 years, four sleep disorder specialists, many different CPAP machines, a failed throat and nose surgery, I finally received successful help from Dr. Sievert at Westlake Family Dentistry. The dental appliance he built for me has decreased my sleep apnea episodes from 36/hour (severe) to 2/hour (normal). I feel better and am full of gratitude for his care. Jeannie Woehl

My husband and I have been going to Westlake Family Dentistry for just over two years. Dr. Sievert and his staff are very professional and friendly and always talk us through procedures, which really helps with any dental anxiety. (They have headphones, too, if you are having a long procedure which is super nice and helps to relax.) He has the nicest staff – Carrie, Bri, Emily, Lauren, etc – awesome team! Dr. Sievert pays attention to detail and is very thorough in his work, whatever it may be. We have trusted him with everything from deep cleanings and fillings/crowns to Invisalign and veneers and are always happy. I have suffered from dental anxiety most of my life so it it great to find a dentist’s office that I can be comfortable in and know I am well taken care of. Thank you, WFD!

I love Westlake Family Dentistry. Every time I go in, Alexa (at the front desk) greets me by name (and says it correctly, which is rare). My hygienist says my name right, and remembers life events I’ve told her about 6 months ago (I’m getting married next year), and asks about them. Dr. Sievert remembers life events too, and cares about me as a person, as well as my dental hygiene. Everyone is friendly, and no-one lectures me about my habits if I have lapsed on anything (flossing/etc). Every dentist/hygienist I’ve visited before has made my gums bleed during a visit (I’m a “mouth-breather” due to allergies, so my gums are sensitive). Westlake Family Dentistry is the first dentist that has NEVER made them bleed. I’m very impressed by that. Also, I never feel pressured to get a fluoride treatment, but it is offered at every visit. Although they have prescription-grade toothpaste, and gum/mints with Xlyitol, they are mentioned with their benefits clearly described, but not pushed/upsold. The Dr. is thorough, but respectful of my time. I never feel rushed, and all my questions are answered, every time. I had a sleep appliance made to help my sleep apnea (which is the original reason I came here- and after this care, I switched dentists altogether!), and it was ready on time, and Alexa and her team did their utmost to have my insurance pay for it all, so that I wouldn’t have to pay out of pocket. The appliance is amazing, and the follow-up care, and studies have been most helpful. Dr. Sievert has been terrific with his communication with my referring Dr. too! I can’t say enough good things about everyone on staff with both their professionalism and their personalities. I’ve even had my fiancée switch his dentist. Everyone should go here!

I am a retired dental hygienist, so I know what to look for in a reputable dental office. Westlake Family has a friendly, knowledgeable staff. Dr. Sievert and his hygienist, Katy, were thorough in their treatment and diagnosing. They take the time to educate you so you can make the right decision regarding treatment and care. Never felt pressured. This office is current with infection control practices and new advances in dentistry. I felt very comfortable here. I highly recommend this dental office.

Fast and easy appointment setting by phone. Friendly front-desk staff upon entry. Very clean, well-lit, nice facilities, with what seems to be pretty new and latest-tech for equipment. Dentist himself and the assistants were friendly and professional. They also seemed knowledgeable and answered any questions I had. Already have appointments set to return, and will update my review accordingly. As it stands now, I highly recommend this place.

Having lived in various places and been treated by numerous dentists over the years, I can honestly say that Dr. Sievert and his staff are by far the most professional and courteous practice I’ve ever encountered. From the moment a patient steps foot in the office, they are treated like a member of the family. The quality of the dentistry and hygiene is unmatched and, having been a patient for many years, I’ve never had a negative experience. I would HIGHLY recommend Westlake Family Dentistry to anyone that is seeking a better patient experience in the Lake Oswego area!

The team at Westlake is exceptional! I needed a Maryland bridge updated from my teens and also the veneer to match it symmetrically on the other side. I talked options with Dr. Sievert, he made molds I could see and hold and then was super meticulous with the actual work itself. The quality and precision was great because he has a strong attention to detail. Additionally, it is the right color and symmetry to match my other teeth. His right-hand person, Bri, is considerate, friendly, patient and professional. Highly recommend!! have received several compliments on my smile and the dental work does not stand out or look fake.

Another amazing Experience At The West Lake Family Dentist Office. This is the second cleaning with my hygienist sabrina, and I must say, she makes going to the dental office fun. She has such a great personality and she does an amazing job, you almost don’t realize she has been working on your teeth. Truly painless, great experience again. Highly recommend this practice

Andrea (Source: Google)


I am so impressed with the expertise, efficiency and kindness of this team! I’m very phobic about even simple dental procedures, and Sabrina’s gentle technique made a long-overdue cleaning (thank you covid) completely painless and anxiety-free. Dr. Sievert’s exam was careful and thorough, and his explanation of necessary work made me confident in his treatment plan. And Mary, at the front desk, has endless patience when finding appointments and explaining charges. I’m actually looking forward to my next visit, much to my shock and amazement.

I am a new patient to Westlake Family Dentistry. Recently, the dentist I frequented for many years retired. I hadn’t thought of where I would go to yet, until I had a tooth break! Hence, I needed assistance immediately and since my daughter & her family visit Dr. Sievert’s practice, I thought it was a good place to start. From the first time I arrived with my broken tooth, the entire office staff has been over the top welcoming. Dr. Sievert is extremely thorough & repaired my tooth on the spot. NO waiting, which I so appreciated! Alexa greets me by name & Sandy, who cleans my teeth, helps me in every way possible to increase the health of my gums. She is VERY explicit in how to maintain my home care, walking me through the process so I totally understand. I’ve never been one that enjoys going to the dentist, but I sincerely enjoy the people & the care I receive. I couldn’t be more pleased to be a patient of Dr. Sievert & his staff.

I am so glad my friend recommended Westlake Family Dentistry to me. As a new patient last year, I was nervous about seeing Dr. Sievert but he and his staff were so warm and professional that I quickly felt at ease with them. I have no hesitation recommending Westlake to others. They have consistently provided top notch care from start to finish. I know I’m in excellent hands with them!

I have always felt 100% cared for from Alexa in the front office who takes care of every detail from the scheduling of my appointments to explaining to me what my complex treatment plans mean and how they work to MY benefit. Next is Sandy who has always greeted me with a smile. Her genuine interest in me and my family is comforting. Her words of encouragmenet, firm and wise advice re: proper care of my teeth and gums is spot on. My comfort and health is clearly very very important to her, Alexa and Dr. Sievert. What an awesome team of professionals. It is clear to me that Dr, Seivert has set the bar extremely high. He leads by example. Just when I thought things can’t get any better Dr Sievert proves me wrong.

I just moved here from Ohio with My wife Julie last june, and we needed to find a dentist, after searching we have found a great one in Dr. Sievert. He and his staff are amazing. They performed a very thorough exam and detected some problems I had and gave me a plan to fix them at my discretion and timeline. Everything was explained with the pluses and minuses of it all. I had a few crowns replaced and he did an amazing job, pain free and his assistant Brie is one of the best assistants I have ever had work with me.His office staff is extremely good with working with insurances and explaining all the details of costs up front. Dr. and his staff treat you as their most important patient. This is a must for all your dental needs. Thanks for everything…Bob

My husband and I have been going to Dr. Sievert for years and could not recommend the Westlake Family Dentistry team enough. I recently had been in pain for several weeks and Dr. Sievert and his front office staff were quick to get me scheduled and found that I needed a root canal. Dr Sievert made sure I understood what would be done during the procedure and went out of his way to make me feel as comfortable about the process as possible. I have always felt that he and his staff maintain a high professional standard and take great care in their patient happiness and satisfaction. The procedure was painless and relatively quick and a few days after I felt as good as new. My husband and I trust Dr. Sievert and his staff to provide professional and honest opinions regarding our dental hygiene and care. I would highly recommend this place if you are seeking a new dentist.

A fantastic doctor with an outstanding staff and facility. My entire experience to date has been extremely positive; eliminating my previous nightmares and desire to avoid the dentist at all cost. You will find the entire staff to be highly personable, notably competent and very helpful whether it is scheduling your next appointment, addressing your billing questions, or explaining the next steps in your dental procedure. I would highly recommend this dental office if you are in the need, or searching for a new dentist. I know my entire family and I are glad we lucked into finding and visiting the Westlake Family Dentistry practice.
