Dr. Joson is the BEST! Super patient and knowledgeable. We came here because our last dentist said my son needed a root canal. I wanted to get a second opinion and it turns out no root canal needed. Dr. Joson is honest and she will always choose the best option before drilling into your teeth. I highly recommend her as your family dentist. read more

Went in for a deep clean and some fillings and both the doctor and her assistant were just so nice and patient. Dental visits always scare me, so I am relieved to come to a place where I am comfortable. read more

Long over due for a review. Nice and friendly staff. Clean and on time. They took care of me since I'm a baby and scared of pain.

I'm not sure why this place doesn't have a thousand 5 star reviews yet, they are AMAZING!! If you are looking for a kind, gentle dentist look no further because Dr Joson is for you! Took me a month to get seen but once I got in and they found I needed more work after two years of not seeing a dentist the staff is great about getting you back in right away! Dr Joson, the hygienist and even the lady at the front desk are fantastic and go above and beyond to help, refer (for a orthodontist for my son) and walk you through the things I didn't know or understand. Highly recommend it here!! read more

Love the staff! Love my Dentist! They are very professional and friendly at the same time. I drive 20-30 mins for my appointments but I don't mind because they will really take care of you. Also, their office is so nice and clean! Highly recommended! read more

Excellent customer service. Very knowledgeable and I am never kept waiting. Great staff meets all your needs.

i've been coming here for close to 4 years, and each time has been wonderful. I suffer from anxiety and don't like sitting still for too long and they always accommodate and make sure i'm comfortable. Dr.Joson is amazing and sweet and remembers details about our conversations. she did such a great job with my cavity refills that I was shocked it was done so quickly. her aides/assistants are always super talkative and nice. Mildred is the best and is so good at scheduling and making sure they work around you. cannot recommend this place enough!! read more

A very caring healthcare professional, my dentist for many years now, Doc Joson.

Since moving to SoCal few years ago, finding a Dentist for our Family has been tough, we tried several other dentist/ dental Clinics. We've been going to Sierra Dental Clinic (San Dimas, CA) for more than 3 years now. Clinic is clean, relaxed atmosphere, not crowded. Dr. Joson has a gentle hands and has a superb technique in doing dental procedures. Mildred and the rest of dental staff were friendly, efficient, and professional on what they do. Easy and flexible scheduling. Dr. Joson listen to Clients dental concerns, gives expert advise, and provides different options based on dental needs and affordability. read more

Visiting California from Colorado I found myself needing emergency dental work. I had lost a Crown and unfortunately that area became infected so I needed immediate service to relieve the pain. I called Sierra Dental and they got me in for an exam almost immediately. They referred me for a root canal to get the area repaired and then scheduled me for a replacement Crown, on which they did an excellent job. The entire staff, from Mildred at the front desk, to Dr. Joson in the chair, were professional, polite, kind, and knowledgeable. I would highly recommend Sierra Dental to family and friends for thorough and courteous service with a friendly attitude. read more

Glenda Joson, DDS - Nice & Modern! - General Dentistry Near Me - San Dimas, California

Everyone here is amazing and super friendly! I was nervous about coming to the dentist because I hadn't been in such a long time but everyone and I mean everyone here was so sweet to me. The office is very clean and they have strict covid screening procedures which I loved and appreciated! I definitely recommend! read more

I cannot say enough great things about this dental office. I had been putting off going to the dentist after several terrible experiences elsewhere. I love my dentist. Dr. Joson is so nice and puts you at ease. The office staff are knowledgeable and very helpful. I have recommended to my family that they change dentists immediately to Sierra Dental! Thank you for helping me enjoy going to dentist again. read more

So I just started going to Sierra Dental (with Dr. Glenda), and she is brilliant! Super nice, easy going, but at the same time very professional. My first visit consisted of a cleaning and an exam. She explained everything and was in such a good mood, that she totally made my visit that much more pleasant. My second visit was for a couple fillings. I should note that I hate dealing with fillings mostly because of the anesthetic shot which is always really painful for me. However, with Dr. Glenda, I barely felt the shot and the whole process was by far the best I've ever experienced. Minimal pain, composite fillings (ie the tooth color ones), and again light humorous conversation. As a result, I left with a great smile, and in a great mood. I am so happy to have found her; definitely the best dentist I've ever had. I highly recommend. read more

My daughter Leriq had her follow up with Vista to complete her root canal and filling and the staff welcomed and took care of us as if we were family... I flew all the way from Atlanta on the day of her appointment.. I was a little late but they were so understanding accommodating.. I need work done to my mouth.. When I have some time I will be coming back.. My review is super late but they remain fresh in my mind. read more

I love having my check-ups here! Nice, easy, and quick! The entire staff is friendly and accommodating from start to finish. Glenda always leaves me with a fresh and gleaming smile. I have never had an issue here. read more

I have been in the look for a good dentist since I migrated to this country. By far only Dr. Joson has met my high expectations. She would give you a thorough treatment plan and explain the procedures to be done. She will also recommend further treatment without being pushy and gives you a chance to weigh your options like how much will be covered by your insurance and what would be affordable . Her hand is also very light. The office is very clean with up to date dental equipment. Has a very friendly & accommodating staff that would feel you very comfortable. I was glad I was referred to her and will definitely recommend to my friends. read more

Best dentist I've ever been to. She has all the newest technology for her office. Takes her time with each patient and isn't in a rush to get you out of the office. The Dr. was also super kind by helping me out when I did not have insurance, and I needed a lot of work on my terrible cavities. I recommend her to everyone in the area. It's also super easy to get an appointment with her and she's available on Saturdays for all you Monday- Friday workers. read more

I was first looking for a primary care physician for my son. After calling and speaking with Mildred, I decided this will be my son's dental office. Soon there after, they became my dental office. From the moment I stepped into the dental office, they have taken care of my son and I. I never have to wait longer than 10 min once we arrive for our appointments. They work with my schedule and even have openings on Saturdays. That helps tremendously so that my son doesn't miss any school time and I don't have to call off work. The doctor has always made sure we are comfortable once we are in her chair. Any questions or concerns before and after our visit, she is willing to answer. I never have to worry or question if the procedure will be painful for my son and I because the doctor is always very careful and makes sure we are fully numb. Everyone working here is very polite and welcoming. I want to thank everyone in the office for they're hard work and professionalism. read more

I've had a great experience coming to this office for the past 5 years. Dr. Joson is really nice and genuinely cares. It is very simple to get an appointment and go through the whole process.
