    Dr. Marin and the others are great! Been coming here for years and they always take care of my…read moreteeth. Everyone is so friendly and welcoming! Thank you all!

    For years I moved from one dental clinic to another in search of the perfect dentist for me and my…read morefamily. But once I found West Covina Smiles, my search was over. With my love for adrenaline-driven adventures, I can say I have a brave soul. And yet, I am a total wuss when it comes to dentists and I would come up with all kinds of excuses to avoid that anesthesia injection. But Dr. Marin's professional but friendly demeanor can put the most anxious patient at ease. The rapport he has with his patients is what sets him apart from all the other dentists I have seen. He takes the time to explain things and he is never in a rush to get to the next patient. Today, I finally came for my filling and as expected, I was asking for the numbing gel before I even sat on the chair. But Dr. Marin's hands are so light I didn't even flinch from that dreaded numbing injection I managed to avoid for months. He's also great with kids! And when you're a parent with a scared child, that can make all the difference. I also would be remiss if I don't acknowledge Dr. Marin great team. They are courteous, friendly and always accommodating. I have never had a negative experience dealing with any of them. And my, are they on top of appointments! Dental visits are never fun. And that's why finding a dentist like Dr. Marin is all the more critical. Kudos to him and his staff for taking care of my family's dental care all these years. Please don't retire.

    I originally found this dental office just by googling a local dentist. They had really high…read morereviews. Within the first phone call, I already understood why. Dominique was very personable! She answered all my questions. Helped me navigate my son's busy schedule and the dentist available times. She was so patient. She told me Vickie would be calling to help me verify the insurance. Ms. Vickie...is the GOAT. She is so kind!! When you meet her, you feel like she's some how apart of your family?? Or like, a friend you've known a really long time. She so just...kind. Went over every detail of the bill. Made sure I fully understood and agreed with next steps. I appreciated that once in office both Dominique and Ms Vickie spoke directly to my children. Acknowledged them as the patients and as people. The office is very clean. What I appreciated THE MOST, and I told them, was their scheduling was superb. We walked in for a 1 oclock appointment, and was seen at 1 oclock. We didn't sit in the lobby waiting. There was no one in there until we left. We've been there 4 times now (kids needed some cavities filled and we spread it out for time) and each time, no one is coming until we're walking out. They have it DOWN. I appreciate people that respect my time. I hate waiting 30 min to an hour or hour. Arriving on time to sit. The technology in office was very good. The doctor was excellent. Explained everything. Give recommendations. Got the work done. I highly recommend it. And once you meet the front office, you'll know they definitely reflect the back office and the doctor. It's great here.

    Let me start by saying 10/10 RECOMMEND! I have always feared the dentist ever since I can remember…read morebut Dr. Tran is absolutely amazing! He is a very honest, knowledgeable dentist and will explain your treatment in detail. He also has an amazing staff working for him. Vickie is super sweet and goes on and beyond to make sure everything is good with your insurance before your visit. Valerie and Dominique were also super sweet to me during my visits, they were helpful in calming my anxiety prior to treatment. They explained in detail the process and reassured me I was in good hands with Dr. Tran. Overall, the office is very clean and welcoming. I will definitely recommend this dental office to my friends and family. I have found my forever dentist!

    wow, i am amazed by the quality of care and the softness of the staff. every team member i spoke to…read morewas very kind, professional, and helpful. they are also well staffed so wait times are short. this was my first visit and i was very grateful at how the providers listened and built a great treatment plan with me. my previous dentists were not as willing to work with me on a treatment plan. in the past, i had been concerned about my receding gum line. my most recent dentist, another private practice, had nothing to say. i got a second opinion and he said there was no concern, that my teeth were growing and elongating. well, fast forward to my visit at west covina dental, Dr Abu took a look at my x-rays and did advise there was a bit of bone and gum loss. finally, i don't feel crazy! it was wonderful to be taken seriously and have treatment to prevent further loss. periodontal services can cost a bit so if i can prevent it further, i will. my hygienist Maria Bonilla made sure the procedure was comfortable and enjoyable. she was a master with the tools and i seriously have never had cleaner teeth. i have quite a few follow ups and i am looking forward to having them as my dentist. shoutout to my dentist Dr Abu, my hygienist Maria Bonilla, Jasmine for finance and Angel for finance and front desk. everyone was awesome!!

    Hi. I came to this dental office around May 2025. I needed crown work done on my tooth, they…read morecleaned the tooth and charged my insurance, trying to upsale me of a zirconian ceramic tooth that they like to add for crown work. Which they promised about 10 years. It's more than a year later now (July 2026), and the crown fell. Not only did the crown cap come off, there is significant decay underneath as a result of extremely poor built crown (fast and cheap). But they charged me $800 for the crown. There's only 2 reasons why decay would form #1. They didn't properly clean the original decay, #2 they didn't seal the crown it properly. Now, my crown came off 3 days ago. I have to get my tooth removed because of this botched work. They were very adamant on selling me the highest quality crown (zirconian ceramic) and charged my insurance all kinds of work done (which they didn't do). This place isn't a dentistry, it's a business that wants to upsale you and make the most money out of you. They really push bs charges so they can charge the insurance of a lot of things and make money. The dental work they do should be sued for. Please avoid this place at all costs

    I cannot recommend this dental office highly enough. Finding a dentist that satisfies an entire…read morefamily's needs--and actually makes them look forward to their appointments--is no small feat, but this team manages to do it with ease. From the moment you walk through the door, the atmosphere is welcoming and professional. The front desk staff is incredibly organized, helpful with insurance, and always greets us with a genuine smile. It's clear that patient comfort is their top priority. Why We Recommend Them: Clinical Excellence: The dentists here are truly at the top of their field. Whether it's a routine cleaning or a more complex procedure, their attention to detail and commitment to quality are evident. A Gentle Touch: For those who might have dental anxiety, this is the place to be. They are patient, thorough, and always take the time to explain every step of the process, ensuring everyone feels safe and informed. Family-Friendly Environment: They are wonderful with children and adults alike. They have a unique way of making the kids feel comfortable and brave, which has turned what used to be a stressful chore into a positive experience for our whole household. State-of-the-Art Care: The office is spotless and equipped with the latest technology, giving us total confidence that we are receiving the best modern dental care available. If you are looking for a dental home where you are treated like family rather than just another appointment number, look no further. This is, hands down, the best practice in the area. We wouldn't trust anyone else.

    I went in for a cleaning. They give me an exam and explained what I needed, but didn't do the…read morecleaning. They billed the insurance company. I didn't want some of the dental services, they were supposed to check on the rate and call me back. I forgot about it. Four months later, I still didn't get a call back from them. I called them about the service quote, they had me on hold for over 30 min. The office manager said she was going to call back in 15 to 20 min later. She never follow up. I called got an answer machine and left a message, very, very, poor customer service. I called them back, next day, I was place on hold 3 times b4 someone finally answer the phone. They said they haven't gotten a quote, after 4 months later. This is the F-ken worst dential office I have ever been to in this area. I highky recommend go to other dentist office with better customer service and forget this office. I would not be surprise if most of the 5 stars are paid.
