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

Ian P. from Arlington, MA (Source: Yelp)


I’ve been going to this practice since it’s original location at 1203 Beacon in 1992 (when I lived upstairs!). I loved Dr. Ken. It moved a few years ago to new and improved digs, and I couldn’t imagine using any other dental practice. Dr. Kwak is great, very personable and professional, and has a conservative approach (will tell you when they will ‘keep an eye on something’ as opposed to when it needs to be taken care of; and I trust her judgment implicitly). And I love Aimee M., my hygienist for the past several years, who has a great touch and is a delight to talk to. I come here every three months, and while I’m not one to say “woohoo, dental visits, oh boy!”, I have had a first-rate experience here and recommend it wholeheartedly.

I can’t say enough about this practice. It’s so clean and they use such modern technology. I’ve been working with Dr Kwak for crown work. She has such a precise eye and a gentle touch. I have dental anxiety and I feel so comfortable with her. I had my temporary crowns in for way too long and they stayed in without issues. My kids and I have seen other dentist too and they are all so kind and they do such great work.

I’m sure I’m not alone in saying I’ve always hated going to the dentist. But after going to Dr. Kwak and her team, I don’t dread it at all! They do a great job making you feel comfortable and also explaining everything you would need to know about your teeth. I’ve never understood what exactly is going on in regard to my dental health, but they spend the time to thoroughly explain. They’re all so friendly! It’s such a welcoming office and I would highly recommend it. I’m confident in saying my teethe are in the best condition they’ve ever been.

We love Brookline Progressive Dental. Dr. Kwak is awesome with my three kids and very kind and patient with squeamish, wimpy me. Her sense of humor and easy, unwavering confidence put me at ease from my first visit. I feel incredibly lucky to have found a dentist who I actually enjoy seeing! When I cracked a tooth last year, she stayed late to fix it the same day so I could avoid any potential complications. Also, when we first switched to her practice, she redid the dental work that my former dentist screwed up and I’ve had no problems with it since. The hygienists are really nice and thorough, too, and give excellent advice regarding daily dental hygiene. The office itself is welcoming and clean, with soft music and tasteful decor, and the desk staff is friendly and helpful. If you’re in need of a new dentist in the Brookline/Boston area, I highly recommend Dr. Kwak. Your teeth will thank you!

I love going to the dentist! This practice is wonderful: clean, pleasant, attractive. And that’s just the space! Dr. Kwak is a miracle — fast, painless, careful, kind. Funny! Every technician and staff member is also top drawer—pleasant, efficient, helpful. Who would ever have thought I’d look forward to visiting the dentist? I do now. Thank you to everyone at Brookline Progressive.

Caryn S. from Watertown, MA (Source: Yelp)


This great smile was given to me by Dr H. Kwak, Brookline Progressive Dental Associates . She is incredible. She meticulously  redid my teeth to look and function completely naturally, and I now smile with full confidence. She and the team are gentle and were sensitive to the fact that I am a very squeamish patient, and they used a variety of interventions to make the process virtually painless. It is a sincerely caring patient centered practice I would refer without reservation . Go here if you are considering any restorative dental work and you will be thrilled with the results .

Katy B. from Boston, MA (Source: Yelp)


When my 3 year old daughter bruised her gums and we needed to take her to a dentist, I knew I had to get up the courage and go too–for the first time in 18 years!!!!! I was truly terrified, but a friend had been recommending the Brookline Progressive team for a while, so I did it, I went. They were so, so kind, even though my gums were a wreck. Fast forward 3 years and I just got a great cleaning and check up, with news that my healthy gums continue to improve! I really thank my lucky stars that I have been under the expert care of Dr. Kwak and the team of kind, thorough, gentle hygenists. Sheesh! I wish my younger self could have had this experience, and saved myself years of pain and anxiety.

First the office is exceptionally clean and beautiful – very relaxing. The staff is calm & organized. This help because when it comes to dental work I am a train wreck – the worst patient ever. Dr. Kwak is amazing, she has an amazing technique administering novocaine (I’m extremely needle phobic too). Her skills, eye, and hands are truly exceptional. Dr. Kwak also made me feel like I was part of the procedure and made sure that I was comfortable from start to finish. When the procedure was done and I finally looked in a mirror I actually broke down – an amazing transformation.

More than pleased with Brookline Progressive Dental! Had recently changed when my dentist switched his practice. Everyone in this group is amazing and made me feel so comfortable! I was impressed and reassured to see all Covid -related safety precautions being followed. Front desk staff (I met Victoria and Emily) are professional, friendly and efficient. Dr.Kwak put me at ease with her kind manner. Shout out to Taniya, an excellent hygienist! Just returned from my next visit at Brookline Progressive Dental. I continue to be pleased with this practice. My visit ran smoothly from start to finish. My hygienist, Ashley, explained everything she was doing along the way, and easily answered any questions. She was awesome! I always felt at ease! Front desk staff are exceptional.

Wilson K. from Concord, MA (Source: Yelp)


The best dentist I have ever had. Expect a basic, no frills office and an honest, easygoing, simple style that leaves you feeling at ease and as if you got every penny you spent in care and advice. My third year with Doctor Thomases and I am always amazed the place is not PACKED. Again, I suspect it’s the decor and “old school” look and feel. Please look past this. He is top notch in every way.

Davy L. from New York, NY (Source: Yelp)


I was referred here by my dentist in San Francisco. My dentist in San Francisco had a dental hygienist that moved to Boston and is working here. Firstly, the place is super modern, clean and a pleasant office to be in. Really helps when you’re going in for dental procedures! For cleanings, I’ve had Aimee (the one that used to work in SF) and she’s wonderful. Just like my great experience in SF, the cleaning is not stressful and actually quite delightful. She also shows the problem areas that I’ve had with plaque build up. For other dental operations, I’ve had Dr. Kwak. She is truly an amazing dentist and person. I had to get some cavities filled in between my back two teeth. I’ve got quite a bad gag reflex so you can imagine how bad it is to do anything back there. The procedure was quite a struggle for me, having to take breaks and triggering my gag reflex. Dr. Kwak was super calm the entire time and was not annoyed or frustrated at the situation. Her attention to detail for making the patient comfortable is super admirable. When numbing your teeth, she hides the needle out of your view – something small, but helps the patient not freak out. I had to come back for a refilling due to a gap. I was honestly terrified of the operation given what I experienced the first time. But she managed to complete the whole operation in less than 10 minutes and it was 10000x better than I anticipated. It’s a bit inconvenient for me to come, but given my experiences here, I’d come back again and again. And possibly even look forward to it.

This is the only Dental Office that I will go to. Dr. Kwak is the BEST dentist I have ever had in my life. I am 70 years old. She and her entire staff are competent and kind. Before finding Dr. Kwak, I needed anti anxiety medication before sitting in a dentist chair.. Now I don’t. This how dental practice should operate. They are exemplary! Linda A BSN CCM

Rebecca T. from Charlestown, MA (Source: Yelp)


This place is amazing. Dr. Kwak was recommended to me by a good friend who is terrified of dentists…and she said that Dr. Kwak and her team were excellent with her. Since I needed some work done, I booked an appointment. The building itself doesn’t look like it would house a dentists office – you take the elevator up to the 3rd floor – but once you’re in their office, it’s extremely clean, updated and nice. The receptionist is always friendly and I’ve never had to wait more than 5 minutes for my appointment. Today, I had to get a deep cleaning (scaling) which I’ve heard can be painful, but Aimee is amazing!! She explained everything she was doing, and said that I might feel some pressure – but she was so good, I didn’t feel anything and am recovering well. I am so glad I found this place and will continue to go here for my care!!

Erikka M. from Los Angeles, CA (Source: Yelp)


Was recommended by a friend to Dr. Kwak a few years ago, as I had moved to area and need a new dentist. The office isn’t in the best building, but there is ample 2 hour free street parking and once you walk into the actual office you’re confused on whether you’ve ended up in a spa or dentist office. I’m personally not a big fan of dentist visits in general, so this little things like offering free water and window facing treatment chairs go a long way for me. Dr. Kwak (and the rest of the staff) are friendly and knowledgeable, explaining necessary procedures before preforming the work. For somebody who stereotypically hates the dentist, this one isn’t too bad!

Marni S. from Boston, MA (Source: Yelp)


Let me just start and say, that from the moment I called the office till the end of my visit, the service and kindness was stellar! Its hard to find a dentist that is honest and tells you what you need and not looking at the dollar signs. Dr. Kwak was very sweet but honest about the work I needed done. I had a cleaning as well with her Hygienist Nini. She was gentle and patient with me.. I have the most sensitive teeth… lets just say, I am probably one of her most annoying patients lol! She was amazing and very educated about oral care! I will definitely be back and will be referring anyone that needs a new dentist. On a side note the office is super modern and clean, it was beautiful! Super impressed!

Jodie S. from Brookline Village, Boston, MA (Source: Yelp)


This dental practice is simply the best. Dr. Kwak is so thorough, expert, and just puts you at ease. She reviews your choices and supports you to make best decision. Her staff is also top notch. Everyone there is personable and knows what they are doing. They did a great job with my daughter’s invisilign as well. Have no dental fear! Brookline Progressive is here! I guess you can see I like and trust them.

Jordan P. from Allston, MA (Source: Yelp)


I’ve been coming here for over a year now and Brookline Progressive is the best dentist office in Boston–maybe the world. Everyone who works in this office is friendly, professional, and more than competent. Linh, who handles appointments, is phenomenal and extremely accommodating. Paige, my hygienist, is a pro and always so nice to talk with. Both Dr. El-Rafie and Dr. Kwak are wonderful dentists. I’ve had to have a number of fillings in the past year (5 to be exact ¯\_(ツ)_/¯) and Dr. El-Rafie has made them as easy and stress-free as possible. I’ve never once felt pain or discomfort during a procedure–I actually don’t even feel the numbing shots he’s that good!! I can’t recommend this office highly enough. It’s a mistake to go anywhere else.

Best dental office hands down!!! The experience is like no other. From the beautiful interior, to the staff and the treatment. Everyone is willing to go out of their way to help you in any manner needed. This is apparent in the first visit and every one after that! The dentists are specialist, the hygienists are gentle and very thorough, the assistants are caring and friendly and I always get a warm welcoming from the receptionists! If you’re looking for a dental home, you have found it!

Maxine Dolle (Source: Google)


Dr. Kwak is the best dentist I have ever had. She is supremely knowledgeable in her craft. I had several long term problems that other dentists had “watched ” for far too long, including old fillings that had cracked and caused tooth damage. She expertly corrected the problems. She works quickly and confidently. I have never had any pain during her procedures. I have the utmost trust in her work. The entire dental practice is staffed by friendly, warm people. The place is wonderful!

Margaret S. from Brighton, Brighton, MA (Source: Yelp)


I have been going to Brookline Progressive Dental for 2 years and they have provided me excellent care and service.  They have a very calming environment with an indoor water feature and pleasing instrumental music.  I love that they offer appointment reminders and confirmation via text.  I have had negative experiences with my sensitive gums and hygienists who are overly aggressive.  My hygienist has been Paige, and she is very gentle and thoughtful in her chair-side manner.  I have had issues with gum recession, and they recommended a reputable periodontist in the area.  Overall, I would highly recommend Brookline Progressive Dental.

Lee K. from Brighton, Brighton, MA (Source: Yelp)


I can’t say enough good things about Dr. Kwak and her amazing team. I had always been terrified of dentists but couldn’t put it off any longer. Dr. Kwak is fantastic when it comes to working with patients like myself that demand extra patience and a lot of explaining. She is very friendly and does excellent work. I couldn’t be happier with my new crown! The front desk team is always welcoming and helpful, giving excellent explanation about everything that has to do with payments and insurance issues. Always friendly and highly professional on the phone and in person. And I absolutely loved Aimee the hygienist! Best cleaning I’ve ever had!!

Laila S. from Boston, MA (Source: Yelp)


I’ve been going to Brookline Progressive Dental for a few years now and I love it! Everything is very clean and the staff is very kind. Andy in the front desk is always so helpful and the dental teamf is excellent. My most recent cleaning was with Aymee and she was great. She took a long time with me, explained everything and was very sweet. Would recommend BPDT to anyone in Boston!

Rich Caswell (Source: Google)


Post COVID, I felt safe, welcomed and was very pleased with the steps they are taking to insure safety and great dental care. This office staff, dentists and dental assistants are considerate, professional and top notch in the care they deliver. Dr. Kwak is one of the very best dentists who takes great pride in her work. While I don’t always look forward to another visit to the dentist, I travel past many others to go here and am very pleased.

David Medeiros (Source: Google)


First time back at Brookline Progressive Dental Team since Covid hit. I’ve been coming here for years for what I feel is phenomenal dental care with Dr. Kwak. In the past, she has restored a few problem teeth with onlays which is a more conservative approach to a crown when it’s doable. I am so pleased with the results. This time around, I was past due for an exam so it ended up being a yearly cleaning. My old hygienist, Paige moved away so I saw Ashley. I felt right at ease with her. They are back with the tools vs ultrasonic cleaning due to the aerosols released from ultrasonic cleaning. I can appreciate their decisions to keep their people safe and healthy. Even with the old school tools, it was a gentle experience. Of course, the staff were masked up and the waiting area was properly distanced with what I remember as stuffed penguins? on chairs for separation. (nice touch) As usual all my questions about my oral health and teeth were met with kind and informative answers. I had a gum pocket that had turned a little deeper and rather than come back, I asked Ashley if she could take care of it now since it was only one spot. She was game and I got to leave there without worrying that there would still be tarter stuck at the bottom of that pocket. BPDT – great team!

Donna M. from Newton, MA (Source: Yelp)


I have more than a little anxiety about having dental work done.  When my wonderful dentist of 30 years retired and referred me to Dr. Kwak, I trusted she would be good, but never expected the personalized, caring and state-of-the-art care she and the entire team provided.   They absolutely knew how to put me at ease.  They listened, respected my fears and adjusted their treatment accordingly.  I have been back several times and always receive the high quality care.  Absolutely 5 stars!

Kelley H. from Stoughton, MA (Source: Yelp)


I wanted to take the time and say THANK YOU to Brookline Progressive Dental Team! First, the office is absolutely beautiful with soothing music and a waterfall in the waiting room! Second, the dental staff is awesome! They really take care of their patients especially dental-phobics like myself! Third, Dr. Kwak! She is hands down the best dentist I’ve ever been too and recommend everyone to her! I’ve never had a dentist who was so consistent with their work and would take the time to explain everything and make you feel as comfortable as possible! And don’t think because this office is in Brookline it would be hard to get to and find. There’s plenty of meter and/or free parking and right in front of the Englewood T – Station!

Kathryn T. from Cambridge, MA (Source: Yelp)


The whole team here is fabulous! Dr. Kwak examined me and explained exactly what I needed in a kind and courteous manor. I had a filling done here recently, it was quick and pain-free.  They even honored my requested to take photos so I could understand what was going on.  Dr. Kwak is the best, hands down!

Anna C. from Salem, NH (Source: Yelp)


I had never been to Dr. Kwok before, but she was amazing and made everything easy and painless. Her assistant Caitlyn is so warm and friendly that she calmed my nerves and made me feel at ease. The tough part is trying to convince my husband to go to the dentist after 3 years! I’m sure it won’t be hard because my entire experience was relaxing and efficient. Every dentist should be as gentle yet thorough as Dr. Kwok

Deirdre McCarthy (Source: Google)


My current dentist–who is awesome–Dr. Krowne–moved offices and because of this, I needed to begin getting my dental services from Dr. Kwak at Brookline Progressive Dental Team. In short–if you are looking for an outstanding dentist who is kind, super skilled, responsive and supported by a stellar team of dental hygienists (Tanieya is AMAZING), this is the place to go. Additionally—if you have Delta Dental (like I do), Dr. Kwak and her office still ACCEPT Delta Dental—you just need to pay up front but then you get reimbursed. Finding a great dentist can be a huge source of stress. If you are looking for an outstanding dental team that is focused on your long term dental health (not making $ off you), THIS is the place to go. I left my appointment with key dental advice that I know will save me a ton of dental fees in the long term. In addition–the receptionist (Victoria) is fantastic! Go here! Your teeth will thank you!!!

When I started looking for a dentist’s office in Boston I picked Brookline Progressive Dental because of its location. Although, I was happy to find that not only was it a good location but the team and service was great! They are always flexible and easy to schedule with, including Saturday appointments which is nice if you have a busy schedule. They are located by ample parking and right on the green line making it easy to get to and from and the team is professional and always happy to answer questions. Highly recommended!

Carlie O. from Boston, MA (Source: Yelp)


This is the best dental office in the area. From the receptionists, to the hygienists, and dentist everyone is super professional and friendly. My RDH, Paige is the best- so thorough yet gentle, I’m never in discomfort unlike my old hygienist. I’ve seen multiple dentists here at each of my cleanings and they’re all awesome and honest, this office does’t try to scam you or rip you off like a lot of other ones in the area. Let be honest, no one LIKES going to the dentist but the team here at Brookline Progressive Dental is amazing and puts all of your “fears of going to the dentist” at ease.

Rina W. from New York, NY (Source: Yelp)


Dr. Kwak and the whole staff at Brookline Progressive Dental are amazing! I have never liked going to a dentist’s office and have avoided it for the past few years after moving to Boston, but Dr. Kwak and her team makes me feel at ease. I first visited Dr. Kwak for a second opinion. (The first dentist I went to in Boston was very disappointing. I felt like they just wanted my money and I saw the dentist for a total of two minutes, if that.) However Dr. Kwak spent a lot of time with me during my first appointment telling me everything I needed to get done. She was very sweet but very honest about the treatments I needed. She was easy to talk to and very understanding. She was able to answer all my questions and come up with a treatment plan for me. It did not feel like the appointment was rushed. She is a wonderful dentist! I also really hate getting local anesthesia but she made it less painful. She’s good at what she does. All the hygienists that I’ve done cleanings with have been great as well! They are all so knowledgeable and good at informing me every step they’re about to do. On top of that, this facility is extremely nice, new and clean. It has been very easy to make appointments and I’ve never had any issues with billing or insurance. I was always well informed about how much each procedure was prior to getting the treatment. I’ve had to reschedule an appointment last minute due to work and they were kind enough to waive the cancellation fee. I’ve also never had to wait more than 5 minutes to be seen. Everyone is extremely friendly and accommodating! I highly recommended Dr. Kwak and her team to anyone looking for a great dentist and a nice, clean dental office.

Amina M. from Boston, MA (Source: Yelp)


I was seen by Dr. Kwak who was very sweet and understanding. I was running a bit late on one of the appointments and her and the office staff made it a point to help me out. The front office staff were very patient when explaining to me about my payments and insurance benefits as well. Highly recommend!

Eduardo Hariton (Source: Google)


Always had great and timely clinical care with their team for the 3+ years I have been there. This last time, I had a small billing issue where I was charged more than I was quoted. They were able to resolve it quickly, assumed responsibility for it, and adjusted the charge to the initial quote. That is exemplary service and the reason I will continue to go back as it is a great and honest practice.

Darneesh T. from Boston, MA (Source: Yelp)


Excellent dental work and worth every penny. I don’t need much dental work at the moment, but I only trust these guys with my dental needs even though my work insurance doesn’t cover them. No worries–I’ll pay out of pocket for their expertise and friendly service. I’m serious! They’re just that great!
