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

I don’t think there is much to add that hasn’t been said already. However, I would like to reiterate that  EVERYONE that works here does a tremendous job!  Daniel at the front desk is cordial and great with billing/insurance issues. Dr. Winther is as professional as they get, but also very personable. There is also another woman who performs some procedures, it’s sad that I don’t know her name, but she is also amazingly pleasant! I’m pretty sure I’ve dealt with all employees here and nothing but 5 star things to say. They are quite busy, so appointments are usually a month out, but totally worth the wait.

I’ve been very pleased with all of the care and service I’ve received in Dr. Winther’s office. The staff is excellent; Dr. Winther is very professional and I feel comfortable in her care. I actually saw her regularly a few years ago and switched because of changes in my dental plan. But I went back to her and paid for a different plan because of the relatively poor quality on the other plan. Dr. Winther has never tried to sell me a product or service that I don’t need and I have never felt pressure to do a procedure. This is something that I’ve experienced in several other dentist’s offices, and it’s such a turn off. Dr. Winther’s office is top-notch professionalism at its best. Also, super cheap parking across the street in the Marina public lot – I think it’s only like a $1-2/hour.

I love Dr. Winthers. She is kind, fast and professional. She did my new crowns, fillings and veneers and she did a great job on all of them.

Tony C. from Marina del Rey, CA (Source: Yelp)


Dr. Winther is not only a great dentist, she also goes above and beyond to care for her patients. I called her late last night (Thanksgiving night) as I had an infected tooth and was in great pain. She said she could get to her surgery and treat me that night! I was amazed she was prepared to do that. I saw her at 10:30 pm and eventually left her surgery around 11:15 pm and pain-free. I can’t believe there are many dentists who’d go that extra mile, that late and on Thanksgiving night. Simply the best.

New patient with Dr. Winther and I am so happy she’s my dentist now! Really friendly and welcoming vibe from first walking in, and Dr. Winther is so patient and made me feel comfortable before we started (crown). She kept me informed upon each step during procedure which is really helpful and I appreciate. She also kept adding chapstick to my lips during procedure which surprisingly is the first and only dentist that I’ve ever had that does this! And to top it off, the marina view from her office while I waited is the best view I’ve ever had when at a dentist! As weird as it sounds, I’m actually looking forward to my next check up!

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


Finaly an honnest dentist,because 99 % of them are for the money FIRST, unfortunately is no second.We need more like her in this world. Don’t be surprised by her look and youth because she’s a pro and skilled dentist.May I add that she cares and she’s a good listener. THANK YOU Dr. WINTHER.

Kristina G. from Marina Del Rey, CA (Source: Yelp)


Thank goodness for Dr. Winther and her staff. Without a doubt, her dental practice is the best I’ve ever had the pleasure of encountering. My husband and I have been seeing Dr. Winther since we moved to the Marina over 10 years ago. As other reviewers have said, she does not push unnecessary procedures (which is very unusual in California IMHO). I trust her completely for all my dental needs. When I cracked a tooth chomping down on a fork, she was available to speak with me ASAP and get my situation taken care of immediately! She basically reconstructed my broken tooth and it looks as good as new. Dr. Winther also assisted me in finding me the perfect night guard and she patiently spent quite a bit of time doing a wonderful fitting for me. She also corrected a previous dentist’s poor work on a filling of mine. Her office facility is clean and beautiful with lovely views of the Marina. Parking is either pay at the deck or across the street for a very nominal fee. Billing issues are nonexistent. The one time there was an error, it was corrected immediately. Also, her support staff, in particular her dental hygienists are incredibly sweet, kind, and have a very light touch when polishing teeth. It’s a pleasure getting my teeth cleaned! Whaaaatt?! Added bonus right there! So happy that my husband and I found Dr. Winther – with her lovely, kind bedside manner, I always enjoy my visits!

Marissa H. from Beverly Hills, CA (Source: Yelp)


Dr. Winthers is wonderful! I truly trust her with my teeth. It is hard to find a good dentist in general but LA as well. The last guy I saw was a complete crook and then I came to her for a cleaning and fillings, and I’m so happy I did. She is nothing like the last. She and her staff definitely care for their patients, it is not all dollar signs. Look forward to seeing the office again soon!! Thank you!

D. F. from Culver City, CA (Source: Yelp)


Dr. Winther is the Best Dentist. She takes her time to make sure that your teeth are super clean and always consults with you before doing any extra work on your teeth and explains why you may or may not need something done. I was explaining to Dr. Winther That I have extremely sensitive teeth and that I would need a bleaching done if possible and if she could recommend something for me. She cleaned and bleached my teeth and I didn’t feel a thing!!! I’m so happy I found her 🙂

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


Been coming here for regular cleaning and some crown work for past 4 years. Their schedule is so packed that you need to make appointments weeks to a month in advance. Doctors are knowledgeable, super friendly and i’ve recommended friends as well who are generally “scared” to go to the dentist. This place is pricey but comparable to other places in marina del rey but if you’ve got dental insurance, everything is a breeze. The online booking tool doesn’t work well since no one contacts me after i put in a request so a phone call is much easier. They sent email and text reminders before your appt.

Randal B. from Petaluma, CA (Source: Yelp)


I’ve been going here for several years now. The staff is always friendly, attentive and efficient and Dr. Winther is great. If you want a dental experience that is of the highest caliber and yet conducted in a casual comfortable manner then look no further.

Liz A. from Newport Beach, CA (Source: Yelp)


Well worth the wait to see Dr. Winther and her staff! I had previously gone to another dentist (first time) and she had told me I had cavities, pushed me to get Invisalign (I had braces growing up), my enamel was wearing down and eventually I should consider veneers . I didn’t have a good experience, teeth cleaning was like my mouth was a car wash and she used a cavitron which made my teeth incredibly sensitive. I didn’t trust her at all and after reading the reviews, I realized that this particular dentist was very dishonest. Fast forward, I made an appointment to see Dr. Winther and today was the day! Her staff is phenomenal, they’re so nice and made sure I was comfortable. Dr. Winther really listened to my concerns (I even wrote them down) and went through each one of them with me…plus you really can’t beat the gorgeous view! She was also incredibly thorough on my teeth cleaning as well. I found out that my teeth are in great shape, I don’t have any cavities and she told me I don’t need Invisalign or veneers. This was such a great experience and I’m looking forward to seeing her and her staff in the near future. It’s hard to find a trustworthy dentist who truly cares about her patients and staff, and she is it! Thank you Dr. Winther and staff!

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


Seriously love this office. I went back for a filling and cosmetic bonding on my front teeth, due to a chip. I’m really anal when it comes to details bc I asked her 3x to fix how it looked so I would really like it. She did and I really love the results. I also added filling in a hole where I constantly would get food stuck. So she fixed this as well in the same appt so I wouldn’t have to come back. I was treated like I truly matter here and I can’t say enough about their great attitudes and smiling faces. Dr. Winther really took her time to ensure I was happy and I recommend her to anyone looking for a great dentist with a great personality to match. Dr. Winther and her staff make me look forward to going to the dentist. Something I am very pleased to say!

Nichole C. from Playa del Rey, CA (Source: Yelp)


Love this office!  I moved to Los Angeles from Denver approximately 3 1/2 years ago and needed a new dentist.  I also had not seen a dentist for several years and am a very nervous patient.  Reading reviews online, I decided on this office, which is in close proximity to home.  Although appointments seem to be difficult to come by, the staff made my appointment, confirmed my insurance and was extremely accommodating.  They also send confirmation text messages to remind you of your appointment.  The day of my visit, the check-in process is digital, allowing you to check-in via IPAD.  Dr. Winther was warm, friendly, engaging and kept me aware of every action being performed. Her assistant possessed the same demeanor.  Their office overlooks the marina, which can be quite calming for a nervous patient!  Definitely a great experience and I highly recommend Dr. Winther.

Had the BEST dentist appointment today, thanks to Jennifer and Dr. Winther. I am a huge baby when it comes to going to the dentist, I am somehow prone to cavities despite taking great care of my teeth, and I also grind my teeth really bad which has led to issues in the past. But Dr. Winther was SO nice and calming and thorough and really put me at ease. Also Jennifer, who did my cleaning, was so sweet and gentle and really took the time to answer any questions I had. It doesn’t hurt that you have a beautiful view of the marina. Dr. Winther is the best, I cannot recommend her enough! As for parking, it’s really easy; just park at Admiralty and Bali in the public lot and you just have to cross the street. I got lucky and someone gave me their parking ticket which was valid for the whole day.

Holly P. from West Hollywood, CA (Source: Yelp)


If you’re terrified of going to the dentist like I am, Dr. Winther is the answer! Dr. Winther is amazing at making you feel comfortable immediately, and she talks to you the whole time. She’s thorough and meticulous but works quickly. Her office staff goes above and beyond, and I’ve never had to wait longer than a couple of minutes to be seen. I’ve never been happier going to the dentist, and it used to be my biggest fear!

Melanie W. from Torrance, CA (Source: Yelp)


I’ve been to many different dentists due to traveling over the years, and I can say with confidence that Dr. Winther is the best! She’s fast, efficient, nice and most of all, she explains the entire procedure before beginning and always makes sure you’re comfortable. I had to get a root Canal done unfortunately, but the procedure was so smooth I almost fell asleep 🙂 Plus every one of her staff is super nice. Thanks Dr. Winther!

Lisa Christy (Source: Google)


My experience at Dr. Winther’s practice has been good overall. I’ve never waited longer than 10 minutes, including when I arrived early for an appointment. Jennifer, the hygienist, is friendly and gives a thorough cleaning, and Dr. Winther is kind and personable. I’ve deducted one star because there is no parking validation, and parking at this building is rather pricey.

Tatiana K. from Marina del Rey, CA (Source: Yelp)


Dr. Winther is our family dentist for the last two years and I couldn’t be happier with her and the staff. New equipment, high quality professional work (all my crowns and filling are in great shape, teeth are happy and the last two visits were just cleanings). I highly recommend her office to all my friends.

Norma W. from Los Angeles, CA (Source: Yelp)


Love Dr. Winther. She is so good at what she does. She is also a true artist. When she is working on you, she is very gentle. Also she is funny and nice, really makes you feel comfortable. Which is not something you can say for a dentist visit, usually. She has done a lot dentistry work over the years for me and my family. Wouldn’t trust anyone else with my choppers. Also most Dentists are all about the $$$ and will make up services you don’t really need to charge you extra. Not Dr. Winther she is ethical and honest. Her office is very cute and clean and her staff is very friendly and easy going.

S. M. from Mountain View, CA (Source: Yelp)


Dr. Wither and her staff are amazing! My dad was a dentist and had treated me my entire life. When he retired, I was scared that I would not find another dentist with whom I was comfortable. I began seeing Dr. Witnther, and she has been wonderful! I had an issue with a veneer breaking off, and she was able to get me in the same day to repair it. It was the day before her wedding, and she was not even supposed to be at the office, but she came in just to see me! I also had issues with the temporary crown getting stained, and the staff was again able to get me in the same day to fix it. Bao has been excellent about returning my phone calls and messages quickly and giving me a treatment plan. Everyone in the entire office is warm, friendly, and welcoming. In addition, they don’t charge you for unnecessary services. I would HIGHLY recommend Dr. Winther and her staff!

Elnaz J. from Los Angeles, CA (Source: Yelp)


I’ve been to Dr. Winther twice now and both times have been an AMAZING experience. First let me say everyone in her office is extremely knowledgable and very friendly. The office is very timely, I have never been there longer than the advised time and they always take me in on time. Dr. Winther did an incredible job on my two fillings. I felt no pain or discomfort during or after the procedure. Sometimes after fillings things feel a little off for a while but not with Dr. Winther. My teeth automatically felt better and back to normal. Her friendly attitude makes you feel and ease and comfortable. Her and her entire staff is great!

Christian E. from Piedmont, CA (Source: Yelp)


Dentists that you can trust are few and far between. Dr. Winthers is the first dentist I have met in Los Angeles that does not try to find something that needs “fixing” unless you truly need it done. The field of dentistry needs more dentists like her and less money grubbing scammers that charge you $$$ for unnecessary procedures and in the end do more harm than good to your teeth; an asset that I would argue is the true window to the soul 😉 Her staff rock too

A. D. from Beverly Hills, CA (Source: Yelp)


GR8 with teeth 🙂 I’m not a “Yelper”, I don’t generally Yelp but I saw these reviews and felt a need to contribute. I HATE going to the dentist but LOVE going to Dr Winther! I have a horrible dentist phobia but Dr Winther is incredibly understanding, caring and gentle!!! I’ve been her patient for 5 years and I can’t speak highly enough about her practice and her staff. Look no further she’s amazing!! I heart Dr Winther to pieces… Reese’s Pieces!

Liz C. from Wilmington, CA (Source: Yelp)


Dr. Winther and her staff are amazing. One of the hottest Dentist in the Marina. Her approach is very conservative with treatment and recommendations. NO UPSELLING! hygienists are awesome and gentle. Getting your teeth cleaned with the best view to the Marina Priceless. Totally worth the wait for my appointments.

Kim V. from Santa Monica, CA (Source: Yelp)


Been a patient of Dr. Winther’s for almost 10 years and think she is exceptional. They dental hygienist is thorough, caring, and gentle with cleanings. Dr. Winther is skilled with her dentistry work, honest, and genuinely cares about her patients. The only downside is that it is tough to get an appointment. Sometimes she is booked solid for months at a time.

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


I had a great experience here. I had to wait at least a month before I was able to get in for my cleaning/checkup, but it was worth the wait. The office was clean, and the staff and dentist were friendly and professional. The view from the dentist chair is fantastic and makes it a little easier to have someone working on your mouth.

Zuki T. from Culver City, CA (Source: Yelp)


I’ve been seeing Dr. Winther and her office every 6 months for the past 5 years. Never had to do anything more than a check-up but the staff, dental hygienists, and Dr. Winther are always friendly and professional (and gentle!) Had to correspond back and forth a few times when I switched jobs and insurance but otherwise no issues.

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


Best Damn Dentist I have ever had in my life! I love Heather and her insanely clean office, and incredibly nice staff. Look no further, hope you can get in! Heather dropped her plans for me once when I had an emergency and treated me after hours! Thank you Heather and Company!

Shai M. from Marina del Rey, CA (Source: Yelp)


I am the world’s biggest wuss when it comes to dentists but I just had my first appointment with Dr. Winther – just an exam and cleaning – and it was easy as pie. I usually cringe at the very thought of anyone poking at my teeth but she and her staff made me feel comfortable and as though my dental health was in good hands. I set another appointment in 6 months and am totally looking forward to it. I highly recommend Heather Winther.

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


I was nervous about trying a new DDS for the first time in many years but had a great experience with Dr Winther and her staff.  The office was clean and pleasant and I was taken in for my new patient appt very quickly. Anna was my assigned assistant and she did a great job of painlessly taking my full set of x rays. As Anna finished up, Dr Winther came in to review them, examine me, and discuss  my needs.  She was very reassuring and I felt confident about what she was explaining. I was also very happy to get my teeth cleaned at the same appointment. Overall a really good experience and I look forward to continuing the relationship for years to come. Thank you!

Erin K. from Topanga, CA (Source: Yelp)


I initially started with this office approx 20 years ago when Dr. Hood was the primary dentist. Then it transitioned to Dr. Winther – who is now the primary dentist. I have always had great experiences and felt I was in good hands. I moved away and started going to another dentist closer to my home, but, was very unhappy. I decided to make the drive and go back- and I am so happy I did. The office staff is very friendly. The hygienist was extremely knowledgeable, gentle and funny. And Dr. Winther is extremely good at what she does. She’s very quick and responsive to questions. A great overall experience. I’d highly recommend this office to anyone and everyone. Big perk- you look out over the Marina and Ocean while in the chair.

Maureen S. from Los Angeles, CA (Source: Google)


I almost don’t want to tell you how great she is because she’ll get too busy for me! I’ve never been compelled to give a dentist raving reviews before but Dr. Winther is professional, personable, and knowledgable. Her entire staff is beyond nice as well and do their jobs with great skill and efficiency. Each person who took care of me was on point and very welcoming. Not to mention that I had the most thorough cleaning in my life. I had no issues making my appointment and they are great about reminding you about your appointment.

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


Am I crazy by saying that I actually like going to see Dr Winther? Possibly. I live in Downtown LA and commute all the way to the Marina, even though there’s probably 561 other local dentists that I could choose. But Dr Winther is my chosen one. Let’s start with parking because it seems to be an issue with other reviewers. Yes, the parking in the attached structure is expensive. It’s the marina, hello? If you don’t want to pay for parking, buy a snack at Ralph’s around the corner and leave your car parked there. That’s legal, right!? Well, that’s what I do. If you don’t mind paying for parking, then you shouldn’t have any complaints. So Daniel is the gem (guy that checks you in) at the front desk. He’s great. He knows his job like a master. He knows the dental industry, how to deal with patients, how to explain billing, etc. Other dental offices treat you like a number or a widget on a conveyer belt when you sign in. You won’t get that treatment with sweet Daniel. Dr Winther and her assistants (Ana and a few other ladies) are the creme of the crop in dentistry. They explain everything they’re doing before and while they’re doing their work, so you don’t have any sudden unexpected surprises in your mouth while you’re sitting there with your mouth wide open. It’s very comforting, especially since so many people fear going to the dentist. The office is super clean and the view of the marina from the dental chair is spectacular and calming. I’ve been to other offices and my view is a cheesy animation of a tooth as a cartoon character, reminding you not to forget to brush and floss.

My husband and I have been going to Dr. Winther for the past 5 years. She is truly exceptional at what she does. She has gone out of her way to help me with issues outside of general dentistry. You never have to wait more than 5 minutes before they take you in. Her staff is professional and polite. If anyone is looking for a new dentist I highly recommend Dr. Winther. She is a true professional and really excels at her profession.
