Dr. Najaran and the whole staff at Sand Canyon Dental have by far been the best experiences visiting the dentist. I’ve moved a lot and have had a lot of dentists, but have been grateful to have found such talented and friendly folks in Irvine the past few years. They are proactive, precise, and excellent with communication. Fillings have been easy and pain free. I recommend Dr. Najaran to all my friends in the area.

I’ve been going to Sand Canyon Dental and personally to Dr. Najaran for over a decade.  She is a professional and a perfectionist!  She has filled cavities and done crowns and I’m am always pleased and never have pain or any problems.  She knows I am sensitive so always checks in and follows up to make sure I am comfortable.  She pays attention to detail and is dedicated to her patients and practice.  I’ve called her in the middle of the night with a dental emergency and she helped me right away!!!  Amazing doctor!  I have recommended friends and family here and everyone has the same great experience!  If you are looking for a good dentist go to Dr. Najaran.

I’m not sure how many people can say this, but I like going to my dentist! Dr. Sepideh Najaran is caring, informative and patient. She definitely enjoys her practice as she is always positive and warm. She takes her time to explain all available options. I have never had an issue with any of the treatments performed by Dr. Najaran. I have to admit that I’m very picky with my choices and I always search for the best. I have changed dentists throughout the years due to constant disappointments, but I’m certain that I won’t be looking for another dentist anymore. … and Stephanie, you rock!

This is the best dental office around! The first impression you get just when walking in the door is phenomenal. Warm, inviting waiting room. Friendly staff. As a dentist, Dr. Najaran is a friendly, polished professional with excellent “chair-side manner”. She really cares about her patients and makes sure they’re always comfortable and pain free. And she treats her staff right, which is important to me as a customer / patient.
Let’s face it — no one likes going to the dentist, but with this place, I actually don’t mind.

Wonderful Doctors and professional and caring staff! I would highly recommend anyone who is looking for an experienced Dentist who always does an amazing job along with staff who’s first priority is patient comfort and satisfaction! I’m so happy to have Dr Najaran as my Dentist!

I recently had the pleasure of going to Sand Canyon Dental. Everyone was so friendly and professional. The facility is very calm and serene. I had to get some work done on an old crown that I needed replaced. Dr. Najaran was able to replace my old crown and I was out of there in no time. I haven’t had any pain, and I am definitely going back for future visits to the dentist. I definitely recommend paying a visit the Sand Canyon Dental… Everyone is super friendly and provided great service.

Best dentist I’ve ever had!

Dr. Najaran is very gentle and detail-oriented. She makes sure  everything is perfect and will encourage you to come back for any adjustments needed. She always explains what’s going on, your options, pros and cons, etc. She always call to make sure you’re doing fine after each procedure.

All the staff are very professional yet personable.

My experience at Sand Canyon Dental have been so great that I recommended my husband to switch to Dr. Najaran. He’s glad he did!

Ean P. from Costa Mesa, CA (Source: Yelp)


My husband and I are patients of Dr.N for a few years now. Being in the dental field myself, I find their office very professional and very friendly! Never once were we pushed on unnecessary treatments. Today my husband went there with our 18 month old. We were a little nervous as we didn’t want to disrupt the peace in the office. And they assured us it was fine. They welcomed our boy and watched him while my husband got his prophy done! We are very thankful and I will be there tomorrow for my teeth cleaning.  Thank you!!!

I will be a returning customer. all Staff is super friendly too

Friendly staff, excellent and meticulous dental work.  Dr. Najaran has been our family dentist for the past 5 years.  She treats us like family.  The staff remember everyone’s names.  They clearly go over all your options with you and never pressure you in making any biased decisions, however provide excellent updated clinical opinion.  I would highly recommend this office, take it from someone who dreads going to the dentist.

I highly recommend Sand Canyon Dental!
Dr. Najaran and Crystal made my visit stress free and comfortable. I was nervous going into the appointment as I’m sure some people feel about going to the dentist, but their professional care and attention to detail made my fears of the dentist go away.
I also recommend getting a whitening treatment done by Dr. Najaran. The results are amazing!

If you’re looking for an office with professional, friendly, and experienced dentists and staff this is the place.
I’ve been going to this office for the past 3 years and I see Dr. Najaran. Every experience I’ve had during my visits have been very pleasant, which is an adjective I never thought I would use to describe a dental appointment. I feel Dr. Najaran is professional, meticulous and very trustworthy. The dental assistants and hygienist’s are experienced and gentle!! I’m so happy I found this office. I would recommend this office with no hesitation!

Sara N. from Newport Beach, CA (Source: Yelp)


I’ve been going to Dr. Najarian for almost ten years and have never had a complaint. The office staff is friendly and accommodating. The office and the dental tools are always clean. I never feel rushed or like I can’t ask all my questions. Dr. Najarian’s work is always thorough and has never caused me additional problems or needed to be repaired. I would highly recommend her and this office.

Sam M. from Los Angeles, CA (Source: Yelp)


I recently had a couple cavities filled by Dr. Najaran at Sand Canyon Dental in Irvine, CA. I was very pleased by her experience and attention to detail. I am not a huge fan of getting shots, but she made me feel calm and the procedure was pain-free.

The office staff was very kind and the overall vibe of the office was very welcoming. I used to live in Irvine when I went to college down there, but now I live in LA and I still visit Dr. Najaran at Sand Canyon Dental because she’s one of the best dentists I’ve ever been to. If you live in the Southern California area and are looking for a dentist, I highly recommend Sand Canyon Dental.

Absolutely the best dental treatment and care in Orange County. My whole family & I have been coming here for many years. Doctor Najaran & (partner dentist) are amazing, I will not go anywhere else. They are extremely knowledgeable, capable ,caring, gentle and will take care of all your dental needs while always being so pleasant. The staff are always very helpful & friendly. If I could give them more than 5 stars I would !!

Was looking for a new dentist last August as I just moved to Irvine . Found Sand Canyon Dental on yelp and chose it purely for convenience . What can I say , I am just mind blown from the entire experience . All the staff member were super friendly and knowledgeable . The facility except looks and feels like a five star hotel . Dr. Najaran is probably the best dentist I’ve ever had.  She answered all my questions  and provided patient education . Sad to say, I’ve never had a dentist who taught me anything  . Flash forward to six months later , they squeezed me in for a last minute cleaning and cavity filling . Patty , the dental hygienists noticed that I had receding gum. She then assessed how I brushed and flossed . Turns out I’ve been brushing and flossing wrong my entire life haha. I really appreciate her taking that few extra minutes to teach me . It’s funny how we are always told to brush and floss but no one really ever correctly shows you how . Dr. Najaran did an amazing job filling in my cavity . I was actually pretty scared from previous experience else where . I remembered it to be super painful and uncomfortable. However , Dr. Najaran made sure I was numbed well before she started working on me . Thanks for everything Sand Canyon!

Dr. Najaran and her staff at Sand Canyon Dental continue exceed my expectations after every appointment. Dr. Najaran is highly skilled, attentive and takes time to listen to her patient’s concerns. I appreciate her conservative approach and trust her and the staff at Sand Canyon Dental 100%. I have had several experiences in the past at other practices where I was told I needed certain dental work, or extra “treatments,” when in fact I did not. It took me years to find Dr. Najaran and I’m so happy I was referred to her- she is the best! Her office is so clean and beautiful, and her staff is so friendly and accommodating. I highly recommend Dr. Najaran!

Dr Najaran and the staff are the best! Like most people, I avoided going to the dentist. Once I found Sand Canyon Dental my opinion of the dentist office has changed. I actually look forward to going, the staff is friendly and honest. The doctor is gentle and kind, I highly recommend Sand Canyon dental

Dr. Najaran and staff are fabulous and provide excellent care. My husband and I have been going there for a couple of years and now our daughter does as well. Highly recommend if you want quality care!

V. C. from Santa Ana, CA (Source: Yelp)


I’ve been going to Sand Canyon Dental and have been a patient of Dr. Najaran for about 5 years and couldn’t be more pleased with their service (I’ve had general checkups/cleaning,  fillings, and crowns). They have a very nice facility, and the entire staff is great! I highly recommend them!

Dr Najaran was wonderful.  needed a crown after a root canal.  She was fast and explained every step of the way.  The staff was also great.

I have been a client here for many, many years. They are always extremely professional, knowledgeable and caring and I would not hesitate to recommend Sand Canyon Dental, they deserve 5 stars and more.

I’m a long-time patient of Dr. Najaran and I know I could not be in better hands. She is knowledgeable, skilled, professional, and very nice too!

Today was my first time at Sand Canyon Dental. From the moment you arrive, it’s clear how much the doctors care about their A+ practice. Stephanie and Crystal greeted me and were extremely friendly as I did my paperwork. Deena the hygienist cleaned my teeth, and didn’t even make fun of me when I couldn’t really talk with her tools in my mouth. Yvonne was efficient with my X-rays and very considerate. Finally, Dr. Najaran took the time to review my films thoroughly, and she gave me great information about my dental health.

I will definitely be returning. Keep up the fantastic work you guys!

Best clinic with best hygiene. And best staff. Doctor is most genuine and gentleman. Really happy with the staff treat. Instruments were hygienic and ambiance was clean. I went there for root canal treatment 2 weeks back and love to share my experience. It was painless and low on pockets. Really happy.

Doug W. from Irvine, CA (Source: Yelp)


Super courteous/friendly staff. Hadn’t been to the dentist in a couple of years and wanted to get in ASAP. Sand Canyon Dental took me right away. Had 6 fillings, 2 of which were handled on the spot during my cleaning and the last 4 took only an hour in a second appointment. Didn’t feel a thing and I left asking “that was it”. Dr. Najaran was very gentle and relaxed. I highly recommend these folks!

Such a caring family practice. My whole family has been treated here and everyone is genuine and sincere and the dentistry is excellent.
