Jovina O. from Rancho Cucamonga, CA (Source: Yelp)


The staff was very friendly & welcoming. I arrived 10 minutes late & they still welcomed me with minimal wait time. Dr. Harry was great! He was very thorough & clearly explained what my problem areas were, along with providing information on what my upcoming procedures would consist of. I would highly recommend this dental office to my friends & family, very pleased with the service I received today!

This was truly the best dental appointment I have ever experienced!! I Am thoroughly impressed and very pleased with the kindness, courtesy, knowledge and professionalism received. The delightful receptionists were a pleasure to talk with, the Procedure Advisor/Financial Planner had such a beautiful spirit and demeanor and made the steps and requirements crystal clear. Dr. Harry is a Dream walking and the other dentists and hygienists were all amazing!! The extraction and first step titanium rods inserted for the future dental implants and crowns was explained to my satisfaction for which I’m grateful. My comfort was of the utmost importance. Including the prescription given afterwards for an antibiotic and for pain meds. After care instructions and a care kit were also given and all questions answered. This was the first in a series of upcoming appointments. I’m looking forward to having the sparkling smile I’ve longed for. It’s finally coming true!! I would rate Golden Smiles Dental a 10+ and highly recommended this office and staff!

I’ve been to a lot of dental facilities but this one is by far the best experience I’ve encountered. They are extremely professional, punctual, and accountable for all their patients. It’s great to be a part of a functional establishment. I go in for my next filling tomorrow!

Renee J. from Rancho Cucamonga, CA (Source: Yelp)


I have been going to the Golden Smile for 6 months and there are 2 things I really like the receptionist Marissa greets me by name. Dr Harry is the best he is always concerned if he is hurting me or if I am having any pain  All of the office staff are friendly and it is always a great experience when I am there

Lindsay C. from Rancho Cucamonga, CA (Source: Yelp)


Over the past few months, I have had tons of work done here. Every single visit, the Dr’s as well as all the staff, have been amazing! I have never had to wait longer than my appt time. I always get greeted by the most wonderful girls at the front.

Awesome staff with fast and friendly service. Golden Smiles Dental is wonderful and does a great job. Highly recommended this office to anyone needing a cleaning, tooth pulled, or surgery. With the well qualified staff and doctors they will take well care of your dental needs

Maral N. from Arcadia, CA (Source: Yelp)


Everytime I’ve gone in to see Dr. Harry he has always taken care of me. This last week i had a sudden horrible pain on an old root canaled tooth and my cheek was starting to  swell. Bridgette was able to get me in within like 2 hours of me calling the office, god bless her.  They got me in and out the office within like  an hour. Thank you again guys

Ilene M. from Rialto, CA (Source: Yelp)


**Updated Review** Bridgette is very professional. Like I mentioned I was a little a disappointed at first but she turned my review around. With her promptness, professionalism,  & her caring attitude. So THANK YOU BRIDGETTE for fixing this in less than 24 hrs. I appreciate that

Dr.Nigoghosian and Dr.Deragobian are extremely professional and knowledgeable. They helped me greatly with the pain I was having in one easy appointment. Bridget is incredibly personable and the entire staff is friendly and sweet. Highly recommended!!

Jared V. from Etiwanda, Rancho Cucamonga, CA (Source: Yelp)


Over a week ago my wife woke up with unbelievable teeth pain, it was Saturday and I was able to walk in and have my beautiful queen taken care within an hour. The staff was geniune and helpful. The dentist calmed her nerves ( she has a huge phobia of the dentist), gave her meds for infection and pain, got her in first thing Monday for oral surgery. True professionals , clean environment , amazing customer service. Highly recommended

Robyn M. from Rancho Cucamonga, CA (Source: Yelp)


This is the best dentist I’ve ever had. They are very professional and courteous. Both dentist and staff communicate with you about the procedure and what to expect. They have a very soft touch from deep cleanings to implants. Even if I move out of the area, they will remain my dentist of choice

Louisa C. from Carson, CA (Source: Yelp)


I’m such a baby when it comes to the dentist but here everyone was so great and kind!! I was reassured everything would be okay from my treatment to my payment options. Definitely made my dentist experience a positive one!! I’m so grateful, thanks again Golden Smiles!

Golden smiles and all its staff is God’s gift to dentistry! Dr Harry, Dr Ankin and also bridgette have been a true blessing in my life ! No only do they do amazing work but they are beyond reasonable in pricing. Never do they judge make ugly faces or shame you. They are loving compassionate and walk u thru every step of the way .. THANK YOU GOLDEN SMILES

Vanessa B. from Rancho Cucamonga, CA (Source: Yelp)


I couldn’t recommend Dr.Harry, Dr. D and there highly skilled team enough! They’ve truly taken “going to the dentist” to an entire new level. The attention to detail and attentiveness they gave me during my appointment was beyond any experience I’ve ever had. Golden Smiles Dental set the bar high. I found my dentist for life! Thank you C’era for all your amazing help and breaking down my insurance

Vanessa W. from Chino Hills, CA (Source: Yelp)


I was in incredible pain last Saturday and they took me as a walk in. Got me meds for the weekend and did surgery Monday ….I’m very nervous at the dentist and they made me feel at home. Incredible service. Loved both husband and wife team. The staff was also very helpful and sweet. If you are looking for a dentist that cares , listens to your concerns and is more than reasonable cost wise this is your place …thank you Golden Smile

Rocio V. from Fontana, CA (Source: Yelp)


I’m so excited to have found Dr.Harry and staff. They’re fantastic! There’s never any rush, no one is stressing and the service is awesome! Usually it takes a while to numb me but I only needed some anesthesia. He saved my molar!!!! I highly recommend this doctor to everyone!!! Thank you Dr and staff!

I give the dentist, the radiologist and the assistant all 5 stars. The front desk leaves a bit to be desired. I have to agree with the other reviews , personality is definitely lacking. The girl that came out to take my temperature did not say hi, NOTHING, just snuck up on me and pointed the thermometer at my head. I thought it was strange also that she took mine and one other guy, but there were 4 of us all arrived around the same time and she didn’t take anyone elses. If it weren’t for the Doctor and the back office staff, Id go somewhere else. I want to give kudos also to the girl in the billing dept. She was super sweet and helpful

Angela S. from Rancho Cucamonga, CA (Source: Yelp)


I highly recommend Golden Smiles Dental. The first time I called was on a Saturday like 2 minutes before they closed. I cracked my tooth that day on a lifesaver and had been putting off the call because I didn’t think I would be able to afford it. The receptionist answered kindly then listened to my concern and patiently booked me an appointment for The following Tuesday. She assured me that they have different types of financing as I knew I was going to need a lot of work done. The 1st appointment they told me what I would need and got me financed even though I thought I wouldn’t qualify for a loan. No Nonsense! I’ve had about 10 appointments since, have seen several different people as they have a doctor for each specialty. I’ve had nothing but positive experiences. The 2nd appointment I needed an extraction to get an implant and I was terrified! The receptionist Natalie was warm and welcoming and Maritza kindly assured me that I wouldn’t feel any pain. Dr. Harry was also very comforting. He has a calm demeanor, took time to explain the process and made sure I was comfortable. He did a great job. I didn’t feel any pain! I left there feeling so cared about. Im so grateful I found this dental office

Cheryll M. from Rancho Cucamonga, CA (Source: Yelp)


This dentistry is Awsome staff is Excellent from Dr D Dr Harry To Staff. Griselda Lorena Ms M at the front desk & Eunice they are very informative & courteous I fell asleep twice during my procedure which I’ve NEVER DONE !!! That’s how confident I was in Dr Harry’s ability I will be telling family & friends about this place 5 stars is not enough I USED To HATE !! the Dentist but no More Thanks Golden Smiles God Bless U

If this is not your Dentist, you have screwed up buddy… Correct yourself, or you will be sorry. Dr. Harry, you and your staff are REALLY good at what you do.. I am very grateful for myself and my family!! Thanks again, you are seriously in the correct profession

I really like this team, the dentists are very kind and make me feel very comfortable, the staff too is very friendly and treat me like someone special. I am having a lot of work done including implants and even though its not a cheap process, I feel good investing into my future smile with this team. I have sensitive nerves in my mouth and I literally feel no pain with these dentist. The facility is state of the art and they even have TV monitors for us at their dental chairs. Thank You Dr. Harry & Dr. Ankin

I had some trouble getting my correct appointment in on the day I requested but they were able to fix the issue and have me seen the same day. The ladies at the front desk and Bridgette are very lively and friendly. The duration of my visit was a bit long but I am sure it was because I was a new patient. The dentist that gave me my fill-ins was able to answer all of my questions and also has a great personality, 3 fill-ins took less than about 25 minutes and she and her assistant had me laughing the entire time. I would come here again

Kylia M. from Rancho Cucamonga, CA (Source: Yelp)


I love this office!!!  The Doctors really know how to get your teeth back to normal/right. Its so clean and very professional in this office  … like I need. I especially enjoy the Special treatment from Bridgette at the door. She always helpful and she makes me comfortable with being at the dentist

Brittini P. from Rancho Cucamonga, CA (Source: Yelp)


I have been taking my daughter to Golden Smiles for a few months now and I have nothing but great things to say! After a few bad experiences with previous dentists I was very wary but I choose Golden Smiles because of their great reviews and I could not be happier with my choice. My daughter is 6 and as you can tell by this picture, getting a baby root canal & a few fillings done is a breeze( she was relaxed & watching Netflix) We have never waited more then 15 minutes, the front desk has been amazing, very knowledgeable and accommodating to all of my family needs. Dr. Harry Nigoghosian is absolutely amazing. He is gentle, takes his time and makes sure to explain everything that is being done. I have already referred two family members and I will be in soon myself for my dental work!

Dominique B. from Pomona, CA (Source: Yelp)


I have been coming to golden smiles dental for a while now and I really love it, I haven’t been able to find a dentist office that makes me feel comfortable and they have friendly staff and great service, another thing that I love is that they keep me up to date on appointments/follow ups. I definitely recommend this dental office

Mark P. from Rancho Cucamonga, CA (Source: Yelp)

My experience with Golden Smiles has been nothing but excellent!!! I’ve been going to see Dr Ankin and Dr Harry for almost the last 3 years since they took over the office. Bridgette, their receptionist is amazing! Very pleasant, accommodating to my schedule and always greets me with a big smile! The office is clean and very modern. Dr Ankin and Dr Harry are very knowledgeable in the field. During my visits they explain my options for treatment and give me payment plans. Let’s not forget to mention how light their hands are when they work on your teeth, you don’t feel a thing!!! Their fees are very affordable and competitive. You can tell their priority is the patient and not their profit.

Dr. Harry and Dr. Ankin make going to the dentist a joyful experience, and this is coming from soneone who has always feared going to the dentist. It does not matter to me which doctor I see when I come to the facility, I know I am going to get the best care. I have had multiple procedures done at Golden Smiles and am extremely satisfied with their work and professionalism. The facility is extremely clean and the staff is beyond friendly. Big shout out to Bridget behind the front desk. Bridgets bubbly attitude always lifts my spirits up when coming to Golden Smiles. I would most definitely recommended this practice

Stephanie J. from Fontana, CA (Source: Yelp)


Dr Harry and his staff is incredible. I put off going to the dentist due to fear and anxiety but he made me feel comfortable and my root canal didnt hurt!!!I am so happy I came and recommend this location to everyone!  Maritza and Laura will treat you like VIPs!

Javier S. from Fontana, CA (Source: Yelp)


I am a new patient to this dental office but i do have to say this, This dental office has to be one of the most friendliest places I have ever been to. As soon as you come in you are greeted by a very warm welcome by the front counter staff. The dental office is very punctual which is great so you don’t wait long in the waiting room to be seen. I was seen by Dr. Harry today and he was such a respectful person and very easy to deal with. I highly recommend this place

Rachelle Estella Mean (Source: Facebook)


The doctors and all staff members were very professional, welcoming and very comforting. The office manager made sure that all my dental needs fit into my financial budget. They continue give me follow up calls as well as make time for me to see me with my concerns. I would definitely recommend Golden Smiles Dental

Elizabeth T. from Corona, CA (Source: Yelp)


I went to Dr. Harry needing extensive dental work, including multiple implants. He thoroughly explained the treatment plan and took the time to explain the how and why of what was being done at every step of the way. Dr. Harry’ price was very fair. I specially like that he is very detailed thorough, and does not take short cuts.  I am very pleased with all my treatments overall
