Your beautiful smile starts here!



Braces for All Ages

No matter what walk of life you are in; child o​r adult- it is never too late for braces. If your gums and teeth are healthy, we can help. We have traditional braces, Wild Smiles (fun shaped braces like hearts, stars, ect.), Invisilign aligners and braces that go behind the teeth. As you can see, we have the perfect solution for everyone!

Flexible Finance Options

We understand that everyone's financial situation is unique, and want to cater to that. We proudly offer in-house interest-free financing, affordable down payments and accept many types of payments and insurances- including Medi-Cal. We are here to help with a common goal- giving you and your family the healthy beautiful smile we all deserve. We look forward to helping you!


​BigSmile Orthodontics has two convenient locations, Chino & Riverside, for you to choose from. This makes seeing us for regular appointments, emergencies or stopping in just to say hi that much easier! Communication is a priority. We also understand how hectic life can be, and we go the extra mile to call and confirm your appointments. Missed the call? We'll e-mail you! We also offer Saturday appointments for the 9 to 5'ers!

State of the Art Technology

​We are proud to offer the latest technology at BigSmile Orthodontics. All of our x-rays are digital, exposing you to a fraction of the radiation that traditional x-rays let off. That combined with our lead apron allows our patients to rest assured that they are being as minimally exposed as possible. You can also take advantage of our 3-D scanners to avoid the gooey molds as much as possible! We also take part of a rigorous sterilization monitoring program to ensure the highest level of sterilization and disinfectant. Our patients are our #1 priority!

Lilly Sandoval

Smile Manager

Hello!! My name is Lilly Sandoval. I have been working as an Orthodontic Administrator and Office Manager for over 25 years. During all these years I gained a wealth of knowledge. I'm able to help our patients with maximizing insurance benefits, flexible spending accounts (FSA), and health savings accounts (HSA).​

My goal and priority is to motivate our team to understand the importance of quality care and great customer service. I enjoy witnessing the huge smile patients have the day the braces come off. 

I am happy to leave the office very day knowing we have changed a patient's life through a new confident smile. 


Smile Coordinator

Hi, my name is Ruby. I take care of the billing of insurance along with scheduling patients and helping them at the beginning of their treatment with paper work.  I have been with BigSmile Orthodontics since the beginning in 2007. I am so happy to see how the office has grown since then and I love the camaraderie that has evolved with the office staff. 

In my spare time I take art classes, hang with my girl friends and take care of my little doggy. I love painting and giving my artwork to my co-workers as gifts! I have two children, one boy and one girl, who are both in their twenties now. I also love zumba and traveling!


Smile Coordinator

Hello! My name is Alicia. I am the  Scheduling/Financial Coordinator for BigSmile Orthodontics. It is my second year working in an orthodontic office, and I am always excited to see all of the beautiful transformations!

 I enjoy spending quality time with my dog, husband and the newest addition to our family, our son! Visiting the beaches, having cook-outs and traveling to new places (for the food) are just a few of the things I When you visit the office, it will most likely be me welcoming you in! I look forward to being apart of making the smile of your dreams a reality. 

Sage O.A., R.D.A

Smile Supervisor

I've been a dental assistant for 9 years, specializing specifically in Orthodontics. I also train and certify Orthodontic Assisting to dental assistants wanting to enter the specialty. I am thankful to have chosen a profession where I enjoy what I do on a daily basis. I enjoy forming relationships with the patients and watching their confidence blossom as their smile transforms.

In my spare time, I enjoy backpacking through national parks. Being in the middle of the wilderness is an excellent escape from the busy and fast paced world we live in today.  Whether at work or home, I enjoy singing (not very good, but I try!), joking around and making people smile.  That is one of the reasons I love my job so much, because I can be myself in the office AND make an impact on people’s lives. The perfect combo for me!

Fabian O.A.

Smile Creator

I have been a dental assistant for Big Smile Orthodontics for almost 3 years. It gives me much satisfaction seeing our patients walk out of our office with the smile of their dreams. I feel very proud to be a part of this rewarding career, and practice.

In my spare time, I enjoy photography. I am the proud owner of a DSLR camera. I like taking artistic pictures at night time. That is where I feel I can capture those once in a lifetime shots. I take my camera everywhere I go to make sure I capture the moment at the right time. I also like to stay active by taking long walks in down town and enjoy the fresh city air. I also enjoy the Japanese culture, I have visited the country once before and can not wait to go back!

Pedro R.D.A

Smile Creator

I’ve been in the dental field for over 20 years as a Registered Dental Assistant, with 10 of those years in orthodontics. I was happy in general dentistry helping patients with several types of dental problems. However, when I changed to orthodontics I knew this was where I wanted to be! I realized that I enjoy helping patients have the best smile they can have, and I enjoyed providing that service with care and passion.

When I have time, I have several hobbies that keep me busy. My first and foremost is my family; My wife for 28 years and my 3 daughters, plus our two little chihuahuas. I love watching soccer games and other sports. I also enjoy working on cars and just relaxing with my family. I like to travel either to visit family or someplace new, near or far. I feel blessed to be in this field because I can help others feel better about themselves. I always keep myself updated and challenged by all the new advancements that are available in orthodontics.

Jessica O.A.

Smile Creator

Hi there! I've been a dental assistant for 4 years now and love what I do. I accomplished my goal in obtaining my Orthodontic Assisting Permit and am proud to be able to provide more advanced treatment to the patients.

My free time consists of staying active whether it’s at my soccer games or out for hikes! The best part of my job is seeing how happy our patients are with their braces coming off and their new smile. When I am not working, I am on the field playing soccer or enjoying my afternoon runs with my two dogs Pancake and Waffle. When at work I am ready to help our patients any way possible, whether it is a question that they have or listening to their opinions about what their idea of the best smile possible would be. I am very friendly and enjoy hearing what our patients have accomplished throughout my day.

Jasmin O.A.

Smile Creator

Hey there! My name is Jasmin, I have worked as a dental assistant for about 3 years now. I finally obtained my Orthodontic Assistant Permit, which has been a goal of mine for a long time and I am very proud!  I am loving the career I have chosen. I enjoy learning new things every day because one can always benefit from learning new things and  getting out of their comfort zone. 

In my spare time I enjoy  relaxing. I also really enjoy binging on Netflix, going on random adventures, trying new foods and handing out with my family. I am beyond thankful for my family! Without my family I wouldn't be where I am today. 



I love BigSmile Orthodontics. They are always so nice and professional. Not only have they done an amazing job on my daughters teeth, they addressed the social aspect and worry about having braces for a young teen in middle school. I highly recommend coming to BigSmile.

We have been coming here for over a year. My son has braces and I can not believe how awesome his teeth are looking. The staff is beyond far the best! I would recommend anyone looking for a orthodontics this is your place. Thank you and keep it up!!
