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

John T. from Portland, OR (Source: Yelp)


I have gone to Dr. Applegate since she took over the practice of Dr. Sommer, and have been completely satisfied with the excellent work. From routine cleanings and checkups, to fillings and crowns, she and her staff have been extremely competent, friendly, courteous and efficient. I really can’t think of how she and her team could improve the quality of service they consistently provide. The facilities and service are outstanding, yet she provides good value, takes time to explain procedures, along with the pros and cons of options. The dental hygenists and assistants who work with her are also expert and friendly. I have no reservations about recommending Dr. Applegate.

I have been going to Dr. Applegate since she opened her practice. Dianne is a very good and careful dentist. I also like her personality because she is warm and friendly. She makes me feel like she cares about me as a person ( I am more than those pretty white teeth to her!) Her entire staff reflects this same warm friendly atmosphere. So, if you must go to a dentist….and yes, you MUST, then this is the one I recommend! Sincerely, Carole Meyer.

The dental hygienist was very careful and skillful in cleaning and polishing my teeth. Dr. Applegate and her staff are excellent in providing me updates on my teeth and I especially like how they look for ways to improve my teeth. They’re great about giving me fore warnings about possible tooth problems that I may need to address or prevent. And the dental hygienist, Violet, is very caring and personable.

Mae E. from Iron River, WI (Source: Yelp)


I have been to many dentists. Dr. Dianne Applegate and her staff are wonderful. From the front desk staff, hygienists to Dr. Applegate they really make you feel welcome and try and get to know you. You don’t just feel like a paycheck. You feel like an important person to them. They did a great job cleaning my teeth. I had a few cavities and they were filled wonderfully. Minimal pain-hey it cannot be painless. I wish I was still in Portland so I could back to them. Very comfortable environment

Rachael J. from Portland, OR (Source: Yelp)


Just got back from my third visit with Dr. Applegate and I still have nothing but great things to say about the entire office. Every staff member I have worked with has been kind and friendly. I use insurance and all of my claims have been timely and correct. The office is bright, clean and up to date with all of the latest technology. I love the text message appointment confirmation and reminders–very helpful! Looking forward to seeing everyone again in 6 months!

Patricia M. from Aptos, CA (Source: Yelp)


Dianne Applegate has been the most professional dentist I have ever had. I had a fear of my previous dentist until meeting Dr. Applegate. I have never had the quality of work that she provided. Extremely caring with the hands of an angel. Her touch was soft and flawless. You would not know when she was in your mouth. We both moved so I no longer had the opportunity of her services, but because she gave me faith in her profession I was able to locate a somewhat good dentist. Never as good as Dianne Applegate. Thank you for caring.

James A. from Portland, OR (Source: Yelp)


I’ve been a patient of Dr. Applegate for several years, dating back to the former dentist who owned the practice. The transition was smooth. The staff and hygienists are friendly, competent and professional. Dr. Applegate has carried on the tradition and exemplifies this standard. The location is great for me in SE PDX and very updated, comfortable and has the latest digital technology. Very happy to be a loyal patient. J.A. SE PDX.

Barbara C. from Portland, OR (Source: Yelp)


Having to leave a retiring dentist after 20 years was stressful for me but not after finding Dr Applegate by way of a friend’s recommendation! Her thoroughness and gentle manner has completely erased the stress of changing dentists. Great dental care! The entire staff is wonderful. I would recommend this dentistry to family and friends!.

Wayne L. from Portland, OR (Source: Yelp)


Dr. Applegate is absolutely the best! I’ve been to my share of dentists and none are as respectful, caring, considerate, gentle, thorough, professional, and fun as Dr. Applegate and her crew. I will never go anywhere else for dental care. Check them out, make an appointment today, and you too will be an Applegate advocate! Wayne “Rick” L.

Jan R. from Portland, OR (Source: Yelp)


I’ve been a very satisfied patient of this practice for more than 25 years and was a little nervous when I heard Dr. Applegate was taking over a few years ago. Not to worry! From the warm, friendly and helpful front office staff, to the adept and professional technicians and Dr. Applegate’s gentle and proficient dentistry, I have been nothing but pleased with the care I’ve received. I broke a tooth late yesterday and they were able to work me in today for a full crown preparation and treat me with a temporary crown with which to go home. Now that is some fast and full service!

Debbie P. from Vancouver, WA (Source: Yelp)


I moved to Portland, OR in 2001 and was referred to Dr. Sommers, DDS at that time. He has since retired and Dianne Applegate, DDS took over his practice. I have to admit I was a bit worried at first since I liked Dr. Sommers and his staff so well. However, it has been a couple of years now, and I am just as happy with Dr. Dianne Applegate and her staff. My hygenist is very gentle and I actually enjoy getting my teeth cleaned. Dr. Applegate is very friendly and also very gentle. I had to have some periodontal work done and their office referred me to a periodontist that is wonderful too. I never have to wait once I arrive, the office is very clean and it has always been a wonderful experience. I do not have dental insuarance and they have always been very accomodating as far as working with me to pay for my services. They are awsome!!!!!!!

Vicky T. from Portland, OR (Source: Yelp)


I have been going to Dr. Applegate’s office since she took over the practice several years ago. When I heard my old dentist was retiring I was upset, but Dr. Applegate quickly won me over. Like most people I hate going to the dentist, but her office understood my fears and helped put me at ease. I had to have a cavity filled and was terrified, Dr. Applegate and her staff were patient, kind and considerate. I recently had a cleaning and the hygienist was great. She did a thorough job cleaning my teeth, I had a lot of plaque build up and she worked hard to get it all off. I did not feel rushed through the appointment like I have felt at other dentists. Great doctor, great staff, great location in SE Portland. I highly recommend this practice.

Connie M. from Portland, OR (Source: Yelp)


When you come in for your appointment the girls at the front desk greet you like a friend. Dr. applegate, her assistants and support staff treat you like your presence there is very important to them.My hygienist is amazing,thank you Jody! Dr. Applegate is professional,kind and gentle. I am very releaved that after being a patient of Dr. Sommers for 10 years, she took over his practice and I could not be more pleased.

Daniella B. from Portland, OR (Source: Yelp)


Dr. Applegate has a wonderful practice conveniently located in SE Portland – I have been going to Dr. Applegate for three years and my appointments have consistently been thorough, efficient, and extremely professional. Both Dr. Applegate and my hygienist always take the time to review my charts, x-rays, and any potentially problematic issues or “watches” with me. Their comprehensive care puts me at great ease; I feel that my short and long-term dental health is in the best hands. The office staff is also friendly and helpful, and the text message appointment reminders are great!

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


I really enjoy having a great Dentist that takes care of my kids teeth and my teeth too. Dr. Applegate and her staff are very nice, knowledgeable and genuinely care about our oral health. They bill my insurance and always answer my questions and concerns. I would recommend Dr. Applegate to anyone looking for a Dentist. WSH.

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


Finding a dentist that is gentle, highly skilled and personable can be a challenge, but Dr. Applegate is all of these things. She and her staff provide wonderful service in a relaxed office environment. The hygienists are always very quick and efficient with routine cleanings and try to minimize any discomfort. Dr. Applegate does a wonderful job of addressing any problem issues and providing me with the best possible dental care. And the receptionists are always kind and helpful when resolving any insurance discrepancies. The text message reminders are a great way to stay in touch with patients. I would recommend Dr. Applegate to anyone looking for a highly qualified and professional dentist.

Mila G. from Portland, OR (Source: Yelp)


Dr. Applegate’s Dentistry is welcoming, friendly and honest about your dental health and care. They’ll even text a reminder about your upcoming appointment which is so convenient compared with taking a call or listening to a voicemail message. If that’s your speed though, they’ll call, it’s up to you. I’m so happy to have found her and her team among all the other dentists in the Portland area. I’ve been going to this clinic since I moved to Portland (1997). They go out of their way to provide a good service and treat you like they value you as a patient, which doesn’t happen everywhere. They’ve even convinced me to floss.

Toni S. from Damascus, OR (Source: Yelp)


I have been coming to this office for over twenty years. When Dr Sommer retired, he promised me he would find someone wonderful to take over and he kept his word. Dr Applegate and her entire team feel much more like a family than a dentist office. I went in today with a very sensative tooth and in a short time its problem was diagnosed and I had a temporary crown with zero pain. I would and do recommend this office to everyone looking for a dentist.

Since I was 5 years old I’ve been a client at a great dentist. There has been a few different owners since then but it hasn’t changed their advantage on caring for their clients. They are very organized and keep all files updated with their clients and are always there to help to make sure your teeth are very healthy! Even though it’s a little bit of a drive for me to get to my dentist I still do it because they make it worth it. Having clean teeth is a nice feeling and they really do an excellent job, I highly recommend anyone that cares for their teeth as much as I do to go there. Dianne Applegate is the special hygienist now and she’s great at doing her job making sure your teeth are in good condition and your happy when you walk out. I hope everyone enjoys reading my review and will benefit from it, thank you and I hope you will go there and try it out.

Shelly G. from Portland, OR (Source: Yelp)


I have been seeing Dr Applegate now since she took over the practice from my old dentist about 3 years ago I think. I have nothing but good things to say about her and all the girls in the office. She is very professional and if I have a problem can get me squeezed in right away. They have all the up to date dental equipment which is very nice. I would recommend her to anyone.

Margaret P. from Portland, OR (Source: Yelp)


I think Dr. Applegate is great. When I first moved here, I went to a dentist near where I live and she wanted to put a cap or partial cap on practically every tooth with a filling and do a lot of cosmetic work and gave me an estimate of THOUSANDS. My insurance doesn’t cover dental, and I need to focus on the care of my teeth first, especially preventive care. My new doctor said her husband was going to a great, affordable dentist, and she recommended the dentist who had the practice before Dr. Applegate. He was affordable, kept an eye on things that might become a problem, fixed them before they DID become a problem, plus he was great with emergenices. Dr. Applegate took over his practice years ago, and seems to have the same philosphy. I’ve been going to her now for years and like her a lot. The hygienists are great too, as well as the people in the front office — they work with me to make things as affordable as possible. They also help me with the appearance of my teeth, but it’s when I ask.

I had a fantastic experience – both the hygenist and the Dr. were very professional, compassionate, and knowledgeable. The office was clean, and everyone was very nice. Dr. Applegate gave me an excellent, honest evaluation for whitening and Invisalign, as well.

Marcia B. from Portland, OR (Source: Yelp)


Dianne Applegate is a very trained and skilled Dentist. I should know I have had 10 different Dentist’s in my life time so far. She is very gentle I have not felt discomfort during the procedures. I am not receiving any free dental care by giving this review. I would recommend her highly.

Seanna M. from Belmont, Portland, OR (Source: Yelp)


Best dentist and staff ever!!!! These women are kind, gentle, laid back and professional. Dr. Applegate saved me thousands of dollars when I went to her for a second opinion. I was told I needed a root canal and instead Dianne saved my tooth and did it without pain. She also saved me from an extremely costly and painful “deep cleaning” procedure the hack I saw before her insisted I have done which she said was unnecessary. This has by far been my best dental experience, and I would recommend Dr. Applegate and her staff to anyone!

Audrey R. from Portland, OR (Source: Yelp)


My family has been going to the same location for dental work for 12 years. When our previous dentist retired and Dr. Applegate took over, we were pleased to receive the same great, professional service we had received in the past. The front desk staff are welcoming, friendly and organized. They seem to enjoy their job and checking in with returning clients. My kids look forward to going to the dentist because they have been treated so well and enjoy the special prize at the end of their visit.I never thought I would say this, but I actually look forward to my cleanings, as well. My favorite dental hygienist at Dr. Applegate’s office is Markieta. I can’t say enough good things about her. She is gentle, kind and an absolute joy to talk to (when you don’t have cleaning tools in your mouth). 🙂 I appreciate having such a great dentist two blocks away from where I live.

Sandra D. from Montavilla, Portland, OR (Source: Yelp)


Dr.Dianne Applegate’s SE dental office location is easily accessible in the greater metropolitan area. The waiting room is clean and the front desk is staffed by friendly informative personnel. My appointments are always on time. The hygienist are knowledgeable and very experienced. Dr Applegate herself is a direct but soft spoken professional. Her personality and demeanor is suited to all age groups. Visiting her dental practice is a pleasant experience. Sandra D.

Shelby N. from Vancouver, WA (Source: Yelp)


Dr. Applegate and her staff are fabulous! Everyone is skilled, proficient and kind, always making me feel comfortable and welcome. My cleanings are always top notch. Dr. Applegate and her hygienists are always willing to take the time to answer all of my questions, which is greatly appreciated. They always go above and beyond to make the experience a great one. The front desk is also very friendly and proficient with great follow up. Thanks guys for keeping my smile bright and healthy! I highly recommend Dr. Applegate and her wonderful staff!

Anna D. from Portland, OR (Source: Yelp)


Dr. Applegate is professional, realistic, and kind. My husband and I have had our teeth worked on by her for the past three years and have had nothing but positive experiences. Her staff is competent and friendly, always making sure that procedures are done carefully with no pain. The office has a friendly ambiance, is clean, and has up to date machinery. Dr. Applegate even found time to squeeze a visiting family member, who had a dental emergency, into her busy schedule. I highly recommend Dr. Applegate if you’re looking for a great dentist!

Jo P. from Portland, OR (Source: Yelp)


I really appreciate Dr. Applegate’s ability to perform dental procedures with such a gentle touch. I’ve had crown work done by her and she did a wonderful job-they look and feel great. She’s very easy to talk with and her office staff is top notch! They all make you feel like part of a family in her office. A great location in Southeast Portland, beautiful modern building, and a very clean office. The front desk is very organized, knowledgeable in dealing with insurance and scheduling appointments, and very good at follow up calls. I have never had to wait for my appointment for anymore than a few minutes and when I needed to get in for an unexpected problem they were able to work me into the schedule. I would recommend this office to anyone who is looking for a great dentist!

Beth A. from Portland, OR (Source: Yelp)


Dr. Applegate is great and so is her crew of dental professionals. I went in to have my cleaning and due to circumstance sbeyond my control, had my 6 and 7-year-olds with me. They offered to give them their cleanings too, despite having no appointment. The were so great. They explained why it was so important to floss, and now my 6-year-old asks me to floss his teeth. My 7-year-old finally spends more than 2.2 seconds on his teeth, watching to make sure his 2-minute timer runs out before stopping. Pure magic! Thank you! Beth.

Laura L. from Portland, OR (Source: Yelp)


Dr Applegate’s business is fantastic. My son and I have been patients of Dr Applegate’s for many years. Her dental hygienists and staff are very thorough. My son and I are lucky, but in the past 18 years we have only had one cavity between us. She and her staff have great chair side manor and state of the art technology. I would recommend Dr Applegate for families: the kids will love the treasures after their appointment and will be excited to return. And for any adult who enjoy freindly staff and curtious of your time. I have never had to sit and wait to get in the chair. If you’re looking for a dentist – you should definitely call Dr Applegate.

Devon H. from Seattle, WA (Source: Yelp)


If you are looking for a dentist, look no further! I have been a patient for 2 years, I have had 2 cleanings and a tooth repair and I would recommend this place to anyone. I would also like to thank everyone for making my experience relaxing and very easy, my insurance was taken and out of pocket expenses were affordable.

Alle M. from Teton Village, WY (Source: Yelp)


Dr. Applegate and her staff are by far the most enjoyable that I have ever worked with. From the text reminders for appointments, easy insurance process and clean and upbeat atmosphere, her practice is one to try out! I have worked with several different hygienists over the last year and a half since switching to her office and each one of them remembers who I am and is so kind thought the entire appointment. It is refreshing to look forward to getting cleanings compared to unpleasant experiences in the past. All in all, if your looking for a new dentist in the area or a switch from your current practice, Dr. Applegate is really worth checking out!

After having avoided any sort of dental care for almost two years I decided that it was time to get my teeth looked at and cleaned. I had heard a very positive review of Dr Applegates practice from my father who had his wisdom teeth removed here. I was not disappointed. The location is nice, and easy to find. The building is clearly marked, but I did miss the parking in the back. I left a voicemail to make an appointment and they called me back in a very timely fashion. The front desk is polite and the ambient is very relaxed, professional and comfortable. At no point through my appointment did I feel uncomfortable, the entire process made me feel welcome and at ease. My teeth are noticeably cleaner and I was able to get some good advice on products for oral care. I highly recommend going to see Dr Applegate, she and her staff are very friendly, warm, knowledgeable and they make the drudgery and terror of going to a dentist a much more enjoyable experience. Definitely a 5 star dental practice.

I was seeing Dr. Sommer since 1990 and after the sale of his practice, I have been receiving great dental care from Dr. Applegate. A different type of dentist but the transition was smooth. I found her highly personable and she listens her patient’s voice and her personality makes it relaxing even though a dental work can be stressful.
