What Our Patients Say

The staff here is always so great, lovely, and helpful. I've been going to Dr. John for 10+ years and highly recommend him! I used to dread going to the dentist before I found Smile Design Center and now I genuinely love going to the dentist! Dr. John is the best! Run, don't walk and keep those pearly whites healthy and beautiful!

Just had to write this review because I moved to California and got a new dentist. I'm honestly devastated because I LOVE this place. I have been going to this dentist since I was 8 years old and I am 23 now. I was never scared to go to the dentist because of these people. Through so many cavities in my teen years to cleanings every 6 months, they have always taken great care of me.

Dr. John Nassar is just AMAZING, to say the least! He explains everything in detail and is extremely patient. He even offered options according to my situation and was completely transparent. I've never felt so comfortable with a dentist before. The dental assistants and front desk staff were polite and courteous. I would HIGHLY recommend this place.

I have been a patient of Dr. John Nassar for over 20 years. He has treated my parents, my friends, my colleagues and many, many people I have recommended over the years. I have an amazing beautiful smile and I owe it to Dr. John... and his wonderful brother Dr. James when he is not available. The staff is amazing.

Can't even begin to say how excellent this dental office is, and the staff members that work within. Growing up, my biggest fear was visiting the dentist and within my first few visits at Smile Design Center, Dr. John and his wonderful staff made that fear go away. Truly exceptional care.

I have been going here for over 10 years. The staff and Dr. John Nassar are absolutely amazing. Dr. John is only my Dentist, but I swear he feels like family now. He truly cares about his patients. A couple of times I have chipped my front tooth and he saw me right away.

Currently here at Smile Design Center w/ Dr James and his beautiful assistant Ashley and I couldn't be happier!! They fixed an issue a previous dentist created with ease and complete comfort. They are true experts in their field. Seriously, don't look any further... come here for ALL your dental needs!

I have been coming here over 10 years and even though it is a dentist office, I enjoy my experience every time. Serena is awesome and Dr. James is great. He knows I am sensitive to pain so he makes sure I don't feel anything during any procedure I have. The dental assistants are friendly and kind.

I can't say enough about what a GREAT dentist we have here. Dr. John just finished fixing a very difficult cavity for me. I can honestly say I felt absolutely no pain. He is an expert. I really mean NO PAIN. And did a beautiful job. I've been seeing him for over 10 years.

I am irrationally afraid of the dentist. I have an anxiety attack every time. Or at least I did, until I got comfortable at this office. Dr. Nassar had to pull a molar and his dental assistant held my hand the whole time, it was really nice. I didn't actually feel any pain, at any time, ever, with any procedure I've had done here.

Came from California to celebrate my son's 21st birthday. He chipped his two front teeth at 7:30 pm on Friday night. I scrambled to find a dentist that was open on Saturdays and could take him in. Dr. Nassar saved the day — truly outstanding emergency care.

Best dental experience in my life. Interactions on the phone - 5 Stars. Front desk and check in experience - Professional, organized and 5 stars. Dental Assistant - Personal, experienced, casual and caring. Dr. Nassar - Knowledgeable, kind, thorough and professional. Highly recommend.

Dr. John Nassar is an amazing dentist. I needed a root canal and I needed it fast. He stayed until 7:00pm to get me taken care of. My entire family goes to him including my two young children and my parents. If you want a high quality dentist that is fair, reasonable and truly cares about his patients then Dr. Nassar is for you.

I woke up with a terrible toothache and contacted SDC (Dr. John) at the recommendation of my sister who has been seeing him for 12 years. The receptionist was kind enough to squeeze me in the same day, even though I was a new patient. The moment I walked in the door I was greeted with warmth and professionalism.

I live in North Las Vegas and drive all the way to Henderson to see them. They are the best dentists and staff that I have ever had.

This is the most amazing dental office! For the first time ever, I was completely relaxed at a cleaning! Dr. James is so nice, I felt comfortable immediately!

Almost anyone I know hates going to the dentist! Not anymore!!! Felt absolutely zero pain and with multiple injections!!! Highly recommend!!! Very professional.

The dentist and hygienist were great. Both were personable and professional. This is definitely the place for me.

I started with Smile Design Center shortly after they opened for business. Both James and John Nassar are better than any dentist I have ever had. Plus the staff is both competent and friendly. I have recommended several friends and all feel the same way. Best in town!

My experience with Smile Design Center in Henderson was amazing. I saw Dr. John and he was very warm and friendly. His assistant, office manager and receptionist were all friendly and equally helpful. The staff and doctors will try and give you the best experience possible.

My visit to Smile Design Center was really great. No problems whatsoever. Everyone in the staff was very professional and helpful. I will look forward to many years of their very caring service and outstanding dental health.

I have been coming to Smile Design Center for just over 6 years. These guys are great. Dr. James and Ashley are awesome and super friendly. The other staff is always nice and friendly. I will continue to come here as long as I live in Las Vegas.

Dr John Nassar is hands down the best dentist I have ever known! Even when it's time for novocaine, I have never even felt a pinch during the injection. His assistants, staff, and dental hygienists are all wonderful.

Love Dr. John, I've been a patient for years, their staff are always friendly, hardly any wait time to see the Doctor. I had a crown fall out over the Holiday weekend and he called me right back and took care of me immediately.

Although I moved from LV 4 years ago, I still call The SDC my dentist. Dr. John and his staff always give me top care. It's worth the time and money to come back for my cleaning and office visits.

Always a great experience for more than a decade. Best dentists and staff anywhere. Never go anywhere else.

I have been going to Dr. John and James Nassar for over 10 years and my whole family really likes the personal quality care the whole staff provides. I would definitely recommend them for all your dental needs.

As always, I had a very good experience. The support staff scheduled me in right away even during the busy holiday season. Dr John was great. He is always so easy to talk to.

The team at Smile Design eliminates the agony of visiting a dentist. They are professional, friendly, competent, empathetic, and punctual. I am fortunate to have found them.

Both Dr Nassar's are miracle workers. Sometimes I consider moving back to Vegas just to see them again. Remember to mock USC while you're there!

This is a top flight dental practice. They have a great staff, and are very personable and quite punctual. Equipment is state of the art. My dentist is Dr. James Nassar and both he and the whole team are outstanding.

Love my dentist, they are so sweet, great service always.

Great place really good people here! Just need to serve cocktails and snacks for these long appointments!

No one should go anywhere else! The staff and Dr. John are wonderful.

Simply one of THE best dentists in All of Las Vegas. Amazing staff and hygienists. Dr. John Nassar did my veneers and they are AMAZING!!!!

I've been going to Smile Design Center for 14 years. Dr. John knows how terrified I am with any kind of dental work and he's so good at calming me down and making me feel comfortable. The hygienists are super sweet and gentle. I'll never go anywhere else for dental work.

"If you are putting off going to the dentist for any reason, please go see Dr. John at Smile Design Center! He truly treats each client as if they were family and he is an artist! My teeth were in bad shape but after a visit to see him, I could not be happier."

"Wonder place to go! Caring and kind. Love the staff and dentists. Prompt care. Easy to get appointments."

"I've been a patient of Dr. John for over 20 years and will always be his patient. I have referred over 30 people to him and they all still see him and love him. He truly is the best dentist I've ever had. My smile is amazing, the staff is absolutely wonderful, the office is spotless clean."

"As a new resident to Las Vegas it's a challenge to find high quality services equal to public reviews. My experience has been above and beyond expectation with Dr. John Nassar at Smile Design Center. Outstanding care and professionalism."

"I love when I can go get a teeth cleaning and the doctors can be honest with you! This is the right place to go! This place runs a very honest business and they are very friendly!"

"I've been coming to Dr. John now for over 10 years. I literally drive out here once a year from California just to get dental work done. That's how good these guys are. I've gotten everything from fillings, to root canals, to simple cleanings and always had a great experience."

"My favorite dentists (the brothers)! Another dentist told me a certain procedure was mandatory and needed to be done asap. I went to Dr. Nassar to get a second opinion and he was completely honest with me. That honesty and integrity is why I keep coming back."

"Dr. Nassar has been my dentist for years now. My hygienist is the best."

"Very professional team, very kind and awesome. This is the best dental office I have been to. I was originally referred to Dr. John but Dr. James took good care of me, very helpful and will answer any question."

"Dr. Nassar is an extremely talented dentist. I've been bringing my mom here for two years for her dentures. Her smile is beautiful and she never has problems. If you're in the market for top quality dental work then Dr. Nassar is the dentist for you."

"Best dentist hands down!!!! Every single one of their staff members is sweet, kind, efficient, and great!!! I have been going here for over 12 years and when the military moved me out of state I still plan my trips around my cleanings!"

"Going to the dentist has always been very frightening for me. I met Dr. James and his staff and from the very first visit he and his staff attended to all my needs and fears. Every visit has been so wonderful. Highly recommend!"
