Excellent dental office. Customer service was wonderful starting with Maria at the front desk. Gil, dental hygienist, and Dr. Ra treated me gently and ensured I was comfortable at all times.

This was first time to Smile Studio in Fontana. The office is brand new, uses new dental technology, and looks beautiful & clean. The employees are all extremely friendly and knowledgeable. I had an excellent cleaning by one of the hygenist's Gil. Dr. Soniya and Roxy did a great job and made me feel very comfortable, as well.

For me, it's important to be able to trust my dentist and their employees. I trust them 100% and have total confidence in their work! I would highly recommend Smile Studio to everyone I know!

P.S. They have an automated Starbucks Coffee and Tea machine free to customers... A very nice touch!

Gil and Sonya were both amazing, first time coming here after having a bad experience from another office. Both Gil and Sonya answered all my questions and was a super friendly environment, from the check in all the way to the check out. I would highly recommend anyone to come here for any dental needs!

I got to the dental office a couple minutes after my appt and didn't have to wait. Gil was personable, knowledgeable and kind. Because I had periodontal disease he recommended a deep cleaning. Explained everything as well as after care.

First time visiting this dental office recommended by a good friend of mine. Loved the staff very friendly informative and professional. All put me at ease with the whole experience. Awesome experience especially for that amped up anxiety I had just making the trip there. Looking forward as hard as that sounds to be serviced by them again. Great crew front desk, xray tech, dental hygienist, and Doctor...and very clean facilities. Thank you all so much.

I came to Sierra dental with teeth issues not knowing what I wanted or if I could afford what I needed They assisted me if They felt I was unsure they would go over it again. After the swelling went down I had to go in for adjustments they didn't mind the staff is magninnocent I am not scared of dentist no more and I'll come back here for anything they're wonderful if you need a dentist this is the one. All the doctors are great I was blessed to have doctor Walter Jefferson and Walter Moran

This was my husbands first visit to this office, he could not stop talking about what a wonderful experience he had. Great service all around. The front office took the time to explain every detail of the services he received and any future needs he may have including his costs and options. He definitely recommends this office

I went in for 2 extractions and a consultation for implants.
Leilani explained the recommendations and pricing throughly, and we began treatment. Dr.Choi was great, quick and to the point with the extractions and bone graft insertion. I did have issues with the healing portion, nothing to do with the procedure itself, but Dr.Choi, Dr.Ra and Dr.Jon were friendly and very helpful with follow ups and ensuring it healed properly. The 24hr emergency hotline was a life saver. Marina helped from the first appointment thru the most recent one and made sure anything I needed was taken care of. Definitely recommend this office and will be continuing here once the new office is opened!
