County of Los Angeles – Harbor City

I’ve been going here for 7 years, including my parents. Best dentist office, best doctors, best staff. They always make sure I’m comfortable.

Dr. Simbol is an amazing dentist. She is very gentle. I've experienced little discomfort with the most invasive procedures. The staff always greets you with a smile and takes care of the insurance billing.

I truly enjoy coming to Tinoco Simbol Dental Care. From the moment you walk in, you can feel a pleasant and peaceful atmosphere, and the office itself is very clean and modern. Lety, the front desk administrator and… biller, always greets me with a warm smile. She is incredibly knowledgeable about insurance coverage and consistently helps me find the most cost-effective treatment options. She also does her best to accommodate my schedule, which I really appreciate. On top of that, she’s simply a joy to talk to. Dr. Diane Simbol has been taking care of my teeth for years, and her work is excellent. She is extremely gentle—so much so that I once fell asleep during a procedure! That says a lot about how comfortable she makes her patients feel. Her colleague, Tess Tinoco, is also wonderful. I can always rely on her expertise, especially when it comes to newer treatments or specialized dental work. The dental assistants are efficient, kind, and professional, which adds to the overall positive experience. The prices are reasonable, and the office hours are very convenient. Overall, I am very pleased with the entire team. I’m even willing to drive all the way from North Hollywood to Lomita because the quality of care and the welcoming environment are absolutely worth it.

Dr. Tinoco and Dr. Simbol have been taking care of my family and I for years. All their staff are friendly and professional. Their office space is always clean and bright. I did Invasalign here with them and was very… happy with how they explained the process and the end results. No need to drive in circles or fight for street parking here either because the building parking lot is large. Highly recommended them.

I am so happy that I chose Dr.Simbol when I was looking for a new dentist! I had several fillings to take care of, so I ended up having 4 appointments with her. Everything was done with such care and professionalism.… She even fixed my very front chipped tooth that I was worried about the most. The color matched perfectly, can't tell that it was fixed. Another important factor I would like to point out is someone at the office always notifies me about the price I would have to pay before starting on any procedure. No "surprise copayments" comes later by mail. Appreciate such honesty! The staff in their office is very friendly and polite, always ready to help. The office is clean. I highly recommend Dr.Simbol to anyone I know!

Best first dentist appointment experience

Lety is the best! Very welcoming and I really appreciate the energy when I walked in. Got a nice clean and they did a great job! Thank you guys🙏

Dr. Tess and her amazing team have been taking good care of my family's dental needs for 10 years now. She's gentle but efficient and thorough. She would give honest recommendations which I appreciate. Their office and… equipment are always kept clean. Some days they'd play classical music which I enjoy. They are all professional, courteous and friendly. If I have questions about billing or schedule changes, Ms. Letty always helps me. I'm sincerely grateful for their team and will always recommend them!

The best dentist!! We drive quite far to stay with Dr.Tinoco. The office is so clean and professional. All rooms are separated and the service is amazing!

Great service nice people

Had a great first time experience! Everyone was super sweet, thorough, and patient. Dr. Simbol took her time explaining and giving advice. Also, shoutout Leti, she was super helpful with setting up the appointment and… contacting my insurance.

came in from a recommendation and had Doctor Simbol work on my teeth, and was very vocal and helpful to make sure I was comfortable. Overall not to timely and came out smiling!

The Best Dental office by far ever in the history of the inception of dentistry. My entire family has been patients of this beautiful staff of amazing ladies for 30+ years, an we refuse to ever let any other dentist… near our teeth. The entire staff exhibits the highest level of gentle care, award winning skills and unmatched professionalism. The facility is very well kept an extremely clean even offering little snacks and a tea/coffee maker for the waiting room. They use state of the art technology to ensure the highest level of quality an extremely accurate results are produced. Most people fear the dentist but for 30 years I’ve always been excited and looked forward to all of my appointments. They are so gentle and caring that I’ve allowed them to perform fillings without the use of numbing medicine an I would still almost fall asleep. Most importantly they are honest an only perform work that is necessary to ensure teeth are in mint condition. I can’t thank these beautiful ladies enough but they all are truly angels from heaven.

Came here based on a good review from an existing client. I was in need of a root canal and a deep clean. Staff is amazing and well informed , best decision ever. I no longer fear coming to the dentist. I recommend… everyone I know to come here.

They have been my dentists since high school (so for almost ten years), and have taken great care of my teeth. Cleanings and fillings are thorough, considerate, and well done. I’ve done teeth whitening before my college… graduation, and my smile looked perfect for my photos. I also use Invisalign through them, and it’s wonderful! Scheduling is easy to navigate. Their office is clean, and always plays relaxing music.

I have dental trauma from previous work I got done when I was younger. Dr. Simbol is very gentle and whenever I’ve gotten work done, she tries to preserve as much of my tooth as possible. She’s also great at explaining… materials that will be used (i.e. for onlays and crowns). Great listener and always able to squeeze me in for an appointment whenever I have sensitivity or any issue. Very grateful for them and their staff is very friendly too.

Love Tinoco Simbol dental. Everyone is so friendly and they’re always on time.

I've moved 30+ miles from here but I still come back for a great service and experience. I highly recommend Dr. Tinoco because of her attention to detail you won't be disappointed, if I can give 10 stars I will.

I'm a very Happy customer for over 20 years!!! DR.TINOCO & STAFF ARE THE VERY BEST OF ALL TIME! I LOVE THEM♡♡

I have been with TINOCO & SIMBOL DENTAL OFFICE for almost 16 years.. A very friendly, caring, from Doctors to Staff cannot compare. I stayed because I know I will be taking care of, not taking advantage for they are… both honest and not a sellers.. Dental office is clean, and all their dental materials are sterilized for every use and I see it on my own eyes.. because I'm very clean and afraid to get diseases or get sick.. Doctor Simbol has a gentle hands and very good in checking if I'm ok or if she wants to hold my hands.. That's how caring she is. Please check it out I have recommended this Dental to all I know and so far all of the people I referred has same experienced.

Love Tinco-Simbol Dental Care been going here for 15 years. With my boys since they were 5 years old. Always got taken care of here.

I've been looking for a dentist that will exceed my expectations regarding bedside manner, and now I've finally met her! Dr. Tinoco is one of a kind when it comes in taking good care of Ur teeth and explaining… everything that need to be done. I don't know if we have the same experiences, but in my previous dental, the dentist won't explain everything to you, instead they will let someone to discuss what needs to be done I think that person is the one who was trained to talk to Ur insurance and Im telling u, they will ripped Ur pockets off! Lol but in Dr Tinoco's dental, I can tell that shes genuine in taking good care of Ur teeth, she explains everything to u and let u see what needs to be done in Ur teeth.. This is the kind of all dentist should be! Also, her hands were so light while checking and cleaning up my teeth which is I really like and admire! Special mention also to Linda (hygienist) for taking extra care of mine while doing teeth polishing! I would highly recommend this dental clinic to everyone who's looking for a genuine and accommodating dentist like Dr. Tess tinoco!

I love this place! Amazing staff and very clean. I highly recommend this dental office for you or your family. Very professional and friendly. Thank you for always taking great care of me. I recently moved but still… love coming here. 5 stars!

I’ve had the pleasure of knowing Dr. Tinoco before she had her own practice. From a teenager with braces to now an adult, her level of care has always exceeded my expectations. Very accommodating and weekend… appointments as well!

The Dentista Ladies are amazing and accommodating! Been with them for more 5+ years now and don't plan to go anywhere else!👍🏼
