I called the office every day hoping for an opening, and thankfully they were finally able to squeeze me in. Dr. Luu agreed to take me even though she didn't have to, and I can't thank her enough for going out of her way to help me. Dr. Luu was absolutely amazing from start to finish. She was incredibly kind, patient, and professional. You can tell she genuinely cares about her patients. She fixed my tooth quickly and perfectly, and because of her, I was able to go on my trip feeling confident instead of worrying about a missing piece of my tooth the entire time. Dr. Luu truly went above and beyond for me. I'm extremely grateful and would highly recommend Dr. Luu to anyone looking for exceptional dental care.

This place is an absolute joke. At first, they were the only option, so we made do. Now, in 2026,…read moreDO NOT START HERE. Do not look the other way AND TRUST YOUR GUT. Let me $2k be the example as to why this place is a total scam, and it's only getting worse.... This office has engaged in improper billing practices. Patients should review all statements carefully. The office billed and collected payment from both insurance and the patient for the same period of orthodontic services, resulting in a confirmed duplicate payment. This has been verified by the insurance provider. When a refund was requested, the office stated it would only be issued at the end of treatment and only if an overpayment remains. This position ignores the fact that this is a confirmed duplicate payment, not a projected overpayment. Under California law, including Business and Professions Code §732, duplicate payments must be refunded within a specified timeframe upon request. Despite this, the office has refused to issue a timely refund. There are also ongoing concerns with communication and coordination within the office, particularly between orthodontic and general dental services. Proceed with caution, actually don't proceed at all, please trust me when I tell you "they are fire and you will get burned" please don't learn for yourself

I've been coming to Sierra Parkway Dental for about four years now, and I can honestly say they've…read morebeen amazing from day one. I originally found them during a dental emergency when my previous dentist couldn't see me at all. I called around to a few local offices, and they were the only ones who called me back and got me in the same day. They took great care of me, and I've been a patient ever since. Since then, my husband has also switched over after having a bad experience elsewhere, and now he comes here too. We are both so happy with the care we receive. The front office team is always friendly, welcoming, and remembers you, which makes such a difference. They're also great with reminders and staying on top of appointments. The dentist is truly exceptional. He's gentle, honest, and never makes you feel like you're being pushed into unnecessary treatments. You can tell he genuinely cares about his patients. I've always had a fear of going to the dentist, but that completely changed after coming here. Now I have no problem coming in every six months or whenever needed. Highly recommend.

I wanted a simple checkup as a new patient - waited over 15 min after my paperwork was done (I'm like... ok fine they are busy). I got x-rays done... waited another 20-30 min for the doctor... and the doc came - did my exam. Said what I needed to get done. Totally understand - I need things done but I have GREAT insurance.... like so great that I don't have a copay for MOST things. so when the financial lady comes by and slaps a $1600 quote in my face and tells me nothing is covered i go... "Just do a regular cleaning - I'll figure out the rest later". Me thinking Ill go back call my insurance on Monday cuz theres a mistake and then Ill make another appointment". She proceeds to push and tell me that "due to your health, we cant do that and deep clean is required and its $200... blah blah blah" im like.. "im not paying that - just do a regular clean for now" and she says "we cant do that" So yes, I leave pissed off for wasting almost 2 hours in this damn office who did nothing for me..... ONLY TO FIND OUT MY INSURANCE COVERS EVERYTHING and she kept trying to push a laser treatment and whatever other crap on me. Like there are other ways and other methods that are covered in my insurance.... and crowns and other things are covered so don't give me options NOT COVERED when I clearly have options that are. When I called on Monday she had the audacity to go "Deep clean is covered.. laser isnt..." THEN CHANGE THE LASER PORTION TO SOMETHING THAT IS COVERED.... "Well your dentist asked for laser..." Honestly, good for him but im the customer and its my wallet not his... I make the decision not him... She should be trained on how to do her job. RUDE AND A RIP OFF. Trying to just take money from customers and then will turn around and still take money from the insurance companies im sure. I will not be taken advantage of and I refuse to let other customers be to. STOP TREATING PEOPLE LIKE THAT because many are already struggling - getting medical care shouldn't be part of the everyday struggle. Worst facility I've ever dealt with.

It's honestly so pleasant to finally find a dental office where you feel truly taken care of. Dr…read more Martinez is an incredible dentist who makes you feel comfortable, heard, and genuinely cared for from the moment you sit in the chair. After going through five different dentists before, I can truly say I have never been treated the way he has treated me. He explains what you need, listens with patience, and creates an environment where you don't feel rushed or judged and that alone makes a huge difference. I'm beyond happy and grateful that I finally found the right place. A very special thank you to Blanca, one of the dental assistants, who made me feel comfortable and cared for even before seeing Dr. Martinez today. Vanessa, the coordinator, has now helped me twice with insurance issues and has always been polite, patient, and professional. Wendy, the manager, went above and beyond when I got my measurements for Perio Protect. There was still some white material left from my mouth mold, and she kindly suggested I step into the restroom so I wouldn't leave feeling uncomfortable. That level of attention to detail really shows how much this team cares. Eileen at the front desk has also been amazing at helping schedule my appointments based on my availability, which I truly appreciate. I also want to give a big shout-out to the hygienist who performed my deep cleaning and the oral surgeon who handled my wisdom tooth extraction, even though I don't remember their names, I'm very grateful for their exceptional work. After three visits, I can confidently say this place is a keeper. Thank you, Dr. Martinez and the entire team, for such an incredible experience. Patience truly is a virtue, trust the process and you'll feel the difference here.

I had a very disappointing experience with West Coast Dental of Fontana. From start to finish, the…read morelevel of customer service was far below expectations. The wait times were excessive and completely unreasonable. Even with a scheduled appointment, I found myself waiting far longer than I should have, with little to no communication from staff about delays. What made the situation worse was the inaccurate information provided throughout the process. I received conflicting details from different staff members, which created confusion and made it difficult to trust what I was being told. Communication overall was poor. Calls were not handled professionally, questions were not clearly answered, and there seemed to be a general lack of organization within the office. Additionally, the lack of basic people skills from some of the staff stood out. Interactions felt rushed, dismissive, and at times unprofessional, which only added to the frustration of the experience. Overall, I would not recommend this location based on my experience. There are many other dental offices that provide more reliable service, better communication, and a more respectful patient experience.

Getting an appointment was fine but they do not care for you in the long term. Dr. Gonzalez took off my retainers and told me my only option was to get braces again. I would've been happy to get it glued or let it be like that to keep my shape. I felt like they were trying to get money out of my minor visit which was ridiculous. I even asked if my teeth would be in the same shape after getting my retainer removed, just cause of how long I had them for. He said that they would stay in shape but the fact that he lied was what lost me as a customer. I have so much anxiety sleeping every night now just because how much my teeth shifts at the bottom. Mind you, the defect in the retainer was from the lack of glue placement of Dr. Gonzalez. His work is great but he does not take accountability in long term errors. Adding on to that, the visit costed 20$! For a 5 minute removal. I came in thinking that I would receive help or some sort of reassurance but was in shock of how I got charged. If that was the case I could've yanked out the permanent retainer at home myself. I do not recommend coming here, please shop around other locations in Fontana. Sincerely, Kimmy
