This is the first time I’ve ever felt compelled to leave a review. Dr Demesa and the rest of the office are so incredibly friendly and welcoming. I hadn’t been to the dentist in many years before coming in, I was anxious about going but so happy to have found this practice and so close to where I work. Dr Demesa makes coming to the dentist the most enjoyable experience it can be.

This place is top notch. Excellent synergy and coordination between staff, hygienists and Doctors Mak & Klieger. The doctors gave great interpersonal skills and I always leave well-informed and confident that I’ve received the most professional treatment.

Sanji Y. from Chatsworth, CA (Source: Yelp)


Jennifer and Dr. De Mesa are excellent. I went for a second opinion and was relieved I did not need to have an expensive and unnecessary deep cleaning that was suggested by a local dentist. Their location is nearly an hour from me, but I have come back twice due to their proficient and reliable practice. I’ll be sticking with them.

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


This is hands down the best dentist I’ve ever been to. I’ve bounced around a lot in last 20 years (army and corporate life) and have been lucky to have some great dentists, but these guys (and their staff) are by far the best. Complete experts in their field grants me the confidence I need in others doing such important work on me, and total professionals in the way they go about it. Whether you new to LA, or just need a dental reboot–these are your people!!! They are so pleasant and down-to-earth, at this point I consider them friends, and gladly drive all the way from Studio City just to keep them as my dentists.

Have I not rated my dentist!!? I highly recommend MKD Dentistry. I’m probably one of the few people who likes going to the dentist. Perhaps it’s because I’ve never had cavities or drilling or the like, so I haven’t had traumatizing experiences. But I have had deep scaling, regular cleanings, and a tooth pulled. I really love Dr. DeMesa, who I followed from his previous office in Pasadena. Dr. DeMesa is super patient with me even though I don’t do most of what he tells me to do. He has a gentle demeanor, but can be tough when he tells you plainly what you need to do to take care of your teeth. Plus, he’s fine with my looking over his shoulder and trying to analyze and interpret my xrays… What is that? Oh that’s normal.. And what is that? I may be the only one who likes a report card for their teeth whenever they do measurements at annual check ups… Can I have a print out of my numbers? Ummm sure… He remembers me each time (probably because I’m a weirdo at the dentist) and is always friendly and nice. The office itself has a good vibe. It’s on the 5th floor of the Pac Mutual Building (the one with the Starbucks on the corner)… and is conveniently located (to me anyway because I can walk from work on my lunch break). Each seat faces a floor to ceiling window so you have nice lighting, it feels open, and has a nice view. If you have to go to the dentist, go to this one.

Aaron P. from Los Angeles, CA (Source: Yelp)


Nobody likes going to the dentist, but i like going here. There’s usually no wait and they do their thing quick and hassle free, without trying to upsell you. Only stuff that’s necessary. You can tell everyone is well trained and experienced in all situations. I wish they did root canals at their office though, instead of referring you to another place.

Jessica M. from South Pasadena, CA (Source: Yelp)


I went for my first visit with Dr. DeMesa and was super happy! The staff were helpful and the location is convenient since I work downtown. Scheduled my next 6 month appointment so I’ll be back soon!

Monica N. from Alhambra, CA (Source: Yelp)


Located inside the historical Pac Mutual building is the very modern, open, loft-like offices of MKD. It’s convenient if you happen to work downtown like I do. There’s also a Pasadena location that I hear gets quite busy. I see Dr. DeMesa, who works out of downtown LA once a week. Thank God I have dental insurance because my teeth are a hot mess and I needed a lot of help. I’ve had the experience of having a bad dentist and also a really good dentist previously. So when I came here for my first visits I was aware of what I needed and what kind of service to look for. I knew already that I needed a long term treatment plan and even though it was overwhelming to get started, I’m really happy a year later and I am so pleased with my results. Even when this office needed to refer me out to another specialist, THAT office was fantastic too. They had such nice things to say about my dentist, his reputation among his colleagues is strong. Dr. DeMesa and his staff are so kind and always very professional. I usually have lots of questions about my insurance plan and payments. Mercedes (at the front desk) answers them all, and even if she can’t answer something on the spot she will follow-up with an email in a day or two. Dr. DeMesa reassured me that even though I was in bad shape in the beginning that I would be ok and he was right!

My wife was in need of a dental procedure. It was either going to cost a lot or a really lot. I had prepared myself for the really lot because; how could I tell the difference? The work, if done well, would never be seen. The bill came in and it was even less than the original quote. I never imagined someone with that level of integrity was still operating in Los Angeles. We’ve found our dentist for life. Thank you Dr. De Mesa!My wife was in need of a dental procedure. It was either going to cost a lot or a really lot.

Dr. De Mesa has been our family dentist for over 10 years. He is absolutely fantastic and we feel blessed we found him. He is extremely friendly, personable and highly skilled in what he does – he’s a natural with both adults and kids. He goes out of his way for his patients – and truly cares about you. He was a dental hygienist before he went to dental school (both degrees from USC) so he has significant experience all-around when it comes to taking care of your teeth! When looking for a dental professional – the combination of excellent skills and outstanding and dedicated patient care is what matters most — and you will find it in this practice and especially with Dr. De Mesa! There are a ton of dentists out there but he is one of a kind! Their practice has grown from the Pasadena location into this beautiful historic space in DTLA with exposed brick walls and lovely city views – and super convenient to the Metro, restaurants and offices.

Melissa H. from Los Angeles, CA (Source: Yelp)


Really nice office with really kind and professional staff.  The dentists are caring and have great personalities/bedside manners.  I no longer dread my dental appointments!.  I see Dr. De Mesa and couldn’t be happier with MKD Dentistry!  After a couple of fillings, I was pleasantly surprised to get a personal email from Dr. De Mesa checking in  Ito see how I was feeling, wow, now that’s customer service!  Finally, a great dental office in Downtown Los Angeles 🙂

Walter H. from Carson, CA (Source: Yelp)


I met the doctors at a LA Chamber event and got their business card.  Needed some cosmetic work done, so I decided to give them a try.  The work that was done was excellent, and I am very happy.  I would recommend them for general dentistry as well as any cosmetic work that you want to have done on your teeth. Go MKD!!!

Jonna W. from Glendale, CA (Source: Yelp)


Hands down, the BEST dental experience I have ever had (and this is coming from a girl who once had Joe Pesci walk in on her cleaning…and stay!  lol.) The ease of making an appointment and the level of customer service I received prior to and during my visit was phenomenal. The PacMutual building is less than a 5 minute walk from my office so it was easy to get there and the suite easy to find. The new offices are beautifully high-tech…and I love the exposed brick charm throughout. I was greeted by the beautiful Teresa and had fun checking myself in with their new touch-screen system. Only waited a few moments before Ishmael greeted me, brought me back for x-rays, and later had a brief Invisalign conversation. Next, Dr. De Mesa  performed my exam and cleaning, and discussed with me next steps in my plan for a more fierce smile. He was very attentive, extremely easy to talk to, and explained everything so well. Afterwards, I even received a tour of the new facility (and some cool pink floss). Thank you Dr. De Mesa, Teresa and Ishmael for an amazing experience. I am so very glad that MKD Dentistry now has an office in Downtown and that you are my new dental team. See you all again in 6-months.  😀

Eve T. from San Diego, CA (Source: Yelp)


I got a groupon for a $45 exam, cleaning, and x-rays. I went in yesterday for my exam and x-rays and had the best experience! The whole staff was really nice and the dentist explained the x-rays in detail – and he didn’t try to sell me any services that were necessary! The office is really nice as well. I highly recommend!

Awesome. I was recommended to this office by a friend and I was not disappointed. Dr. De Mesa even did the teeth cleaning himself – which has NEVER happened for me since I was a kid, it’s always been a dental hygenist! I’m so glad I found this office. The office was clean with a convenient DTLA location, and staff was pleasant, helpful, and well informed.

Karla Torrejon (Source: Google)


The entire staff was friendly, kind, and gentle when working on my teeth. From the front of the house to the dentist and hygienist. I felt comfortable with my experience here so far as a first time patient. I’m due for another visit soon, I look forward to the same experience again!

Syd K. from Los Angeles, CA (Source: Yelp)


Just came back from my third visit to MKD Dentistry, with Dr. De Mesa and the staff. I’m new to Los Angeles, but I couldn’t be more satisfied and grateful I found this practice. I had a terrible experience in San Diego, but Dr. De Mesa, the hygienist, the techs and the receptionist put me at ease and in comfort from the time I waked in to the time I left. I feel so much better about my teeth finally getting fixed. The downtown LA office is sparkling clean and secure. I highly recommend.

Nicole T. from Santa Monica, CA (Source: Yelp)


I’ve been going here since they opened a few years ago. I have been to all of the dentists and hygienists, and I really like them all. I’ve never been overcharged or had any issues with billing or insurance as other reviews have mentioned. There’s no hard up sell like other dentists for extra and unnecessary services. My only comment is that I wish the front desk staff was more pleasant to communicate with… but I like the other staff (dentist and higienis so much that I still feel strongly that they are 5-star worthy. **update** they have new front desk staff and she is lovely, smart and never forgets to follow up with you.

Johnny L. from Los Angeles, CA (Source: Yelp)


I finally found my go to dentist in MKD Dentistry! I had multiple procedures done 3 days in a row and I found that each doctor and hygienist that I met with were all extremely friendly and informative. The pricing was very fair and they never tried to up sell me. I felt that they sincerely cared about my oral health and took time to thoroughly explain my situation.

David Gitter (Source: Google)


Very modern, clean, professional dental office. I feel very comfortable with their care. Certainly, there are dental procedures that are accompanied with some pain, but they strive to minimize the pain and discomfort that come from visiting a dentist. They send out email reminders for appointments, which is helpful. They also have a caring attitude which I appreciate. I am happy to recommend them.

Travis F. from Los Angeles, CA (Source: Yelp)


Great people, and great dentists. They are kind, have pleasant personalities, and are very communicative when they work on your teeth, detailing every item for you as they are working on them. They explained to me which items would and wouldn’t be covered by my insurance (after checking with the insurance I submitted to them) and why they were performing each item on my teeth. They’ll show you the X-Rays, and very clearly display and explain what’s going on with your teeth with regards to what needs to be fixed. The office is comfortable, clean, and welcoming. They also send text message updates/emails, and Mercedes will usually call you prior to your appointment to confirm, which is truly helpful in remembering.

Heidi H. from Los Angeles, CA (Source: Yelp)


Somewhere along the lines I developed real anxiety about going to the dentist. I always put it off until I’m convinced my teeth are about to fall out. So today I finally went, a real ball of anxiety. I’m slightly embarrassed to admit I may have cried, but everyone and I mean EVERYONE in the office could not have been kinder, more patient and understanding. The only thing that would make this office better is if they served margaritas.

Karen S. from Los Angeles, CA (Source: Yelp)


Dr. Dennis De Mesa is so awesome. I had a very early 730am appointment last December and he was there ready for me. I had an issue with a tooth for a while that needed a new filling. I got there and his assistant was not there yet but he managed to do everything really well by himself. He did the filling really well and fast. I was able to get to work on time. He’s an expert. He is very hardworking, very honest and very nice dentist. He truly cares and he would not tell you that you need a service that you don’t actually need. I also had the best teeth cleaning ever. Vivian cleaned my teeth. She is the best! If you need a really good cleaning, look for Vivian. Mercedes is also awesome. She was helpful with setting my appointments and taking my payments. Anyone who is reading this review should go to this dentist. Also, if you don’t have a dentist yet and you are looking for a really good dentist that cares or if you’re not satisfied and happy with your current dentist, you should go to this one. If you have issues and worried about your teeth, Dr. Dennis De Mesa will really help you. You should call Mercedes and make an appointment and you will know what I’m talking about after your visit. I’m writing this review because they really helped me and they provided really good services and they really cared so it’s the least I can do. I’ve been to a lot of different dentists and Dr. De Mesa is really really awesome and very skilled compared to the other dentists and I just want other people to know that.

G. C. from Los Angeles, CA (Source: Yelp)


Very clean and new office in the beautiful, historic Pac Mutual Building. Receptionist is friendly and sometimes if I arrive early, they take me in early which helps if you are paying for parking. There is downtown parking (not validated) in the building or across the street at Pershing Square which I think is cheaper. Dr. De Mesa is great. He is very friendly and makes the visit comfortable especially if you have some anxiety when seeing a dentist :). He will answer all your questions and takes the time to explain things. You can get text reminders about your appts and also confirm by text so you never forget about your cleanings!

Tina G. from Artesia, CA (Source: Yelp)


I came to MKD dentistry for a crown placement and was treated by Dr. Dennis DeMesa.   He eased my fear with his kind and gentle demeanor.  He took his time to explain what my X-rays showed and what the treatment process entailed.  The office staff was awesome and friendly, and the equipment is modern & convenient because my crown was made that same day I got my mold done!!   Dr. DeMesa takes his time and ensures your comfort.  I live in North Orange County and the drive is worth the excellent service!   Come see for yourself!!

Rachel N. from Scottsdale, AZ (Source: Yelp)


I have finally found my dentist in LA!  Dr. De Mesa was BEYOND awesome.  I came in for a groupon deal as a way to try someone new out, and he did an exceptional job on my cleaning and exam.  (Rudy did an awesome job with the x-rays, too…) I have some old bonding on a front tooth that was a bit rough and I thought I had to have it all redone, but Dr. De Mesa told me it was ok and just needed a quick re-polish, which he did, for no added cost.  I’m no longer playing with my screwed up tooth 24/7… Let’s just say he could have redone the whole thing and I would have never known the wiser.  Super honest, very nice, great experience.  I’ll be back

Tai Z. from Los Angeles, CA (Source: Yelp)


Great dentist in downtown LA. Dentists here do the cleanings and I’ve had good experiences with both Dr. Kleiger and De Mesa. Appointments are punctual and quick. Waiting room is clean and quiet. Glad I found this spot, and no desire to look elsewhere unless my insurance coverage ends up changing. Highly recommended.

Christine P. from Los Angeles, CA (Source: Yelp)


I am not someone who likes going to the dentist, but MKD Dentistry is such an inviting practice that they get me there.  Dr. Demesa is so incredibly knowledgeable (and doesn’t judge!), but more importantly very gentle with my sensitive gums and teeth.  I haven’t been so lucky in the past when it comes to pain in the dental chair.  I highly recommend Dr. Demesa (he also treats my two small children who both really like him).  And the new downtown location is modern, clean and comfortable.

Mari Z. from Pasadena, CA (Source: Yelp)


Dr. DeMesa and his staff are fantastic. Dr. DeMesa is extremely knowledgeable and is the most personable dentist I have ever had. His staff is also very welcoming and helpful. Dr. DeMesa does a great job of explaining his procedures and an even better job of getting you to really want to take better care of your teeth. As someone who used to hate going to the dentist, I can’t recommend Dr. DeMesa enough.

Jessica D. from Los Angeles, CA (Source: Yelp)


I don’t like going to the dentist. My first dentist had a terrible personality/bedside manner, and he didn’t really seem to care about what I did with my teeth. He was such a drag, that I dreaded seeing him. My last dentist was very pushy — she started out nice but then would scold me, always tried to make me feel like I had committed a crime for not flossing enough, and tried to freak me out about the perils of gingivitis. I get it, but calm down. No need for extra dramatics when going to the dentist! Plus, she got into this bad habit of charging for things my insurance didn’t cover and had all these hidden costs. Way too much drama. But… she was in downtown near my office – so convenient, that I just stuck with her for a few years and tried to ignore her dramatics. BAD DECISION. I stopped going regularly and of course, my smile suffered. So, when MKD Dentistry recently opened in downtown L.A., I thought I’d give it a try. Fresh start, if you will. BEST DECISION EVER! The doctors/dentists are ALL from USC, and apparently they’ve been practicing together for years, but they’ve just opened this brand-new office/practice downtown (and even closer to my office near Pershing Square!), so I scheduled a cleaning. THANK GOD! I’ve definitely now found my new dental office, and I actually am looking forward to my return in six months. (I can’t believe I suffered for so long w/the last dentist.) BEST THINGS ABOUT MKD: The entire staff is friendly, prompt, and thorough — no attitudes, no weirdness about dental insurance (they take MetLife Dental, which is what I have, and seem to take all others), and they try to explain everything very clearly up front, so you’re not surprised by costs or services. The office space is modern, high-tech and pristine — in fact, there’s no paperwork — it’s all digital and super easy. There’s a very impressive patient tech station in the lobby, and you just login and type your info — so easy. And lastly, of course, the dentist I saw, Dr. DeMesa, is GREAT. Cool guy. He has such a friendly personality, seems really knowledgeable and isn’t pushy at all. He seems to genuinely care about his patients and just helping you do what’s best for your teeth. Great manner about him. I also was surprised that he (the actual dentist) cleaned my teeth at this very first visit together, and didn’t just hand me off to a hygienist. I wouldn’t have minded but talk about quality professional service! If you work downtown, don’t waste your time anywhere else. I’ve lived in downtown for years, have been to four different dentists in the area, and MKD really is a cut above the rest. Easy to get here, easy to get your teeth cleaned on a lunch break. Plus, there’s an awesome view of the city from your dental chair and nice music playing in the background. Couldn’t have imagined a better visit. So, don’t procrastinate — book your cleaning now w/MKD! Your teeth will thank me.
