Very gentle and experienced. First rate schooling and state of the art equipment. I can’t think of a reason you would want to go anyplace else! I’m not crazy about going to the dentist but I honestly enjoy my visits with Dr. Roshangar. The fact that she is one of the nicest people you’ll ever meet, is just a huge bonus!!! This is honestly the dentist you’ve been looking for your entire life. After almost 10 years now, I wouldn’t even consider going to any other dentist!!!

My wife and I have been coming to Dr. Roshangar for several years. I remember my wife’s first visit. When she was done with her treatment she said “she is so gentle!”. I laughed and told my wife to look at the business card in her hand. The tag line on the card said “The Gentle Dentist”. It was truth in advertising! We knew then that we had found the right dentist for us. We have bragged about Dr. Roshangars’ skills to others and now my father is also a client. She is a gifted practitioner as well as a kind individual with a caring demeanor. We would highly recommend her to anyone.

I have been going to Marjan Roshangar DDS for a number of years now and have always been pleased with the service. I have referred other people as well. The office staff is very friendly and polite. Dr Roshangar is very gentle and professional.

I hate the dentist and hadn’t been for years! Dr. Roshangar is super gentle and not at all scary.  Her office is easy to find and is really clean and modern.  There is no waiting and she is always on time.  Her staff is wonderful and very accommodating.

Finally went for cleaning, had been putting it off. Dr. Roshangar is so gentle and wonderful, that I actually relaxed in the chair! When she was done, I couldn’t believe it was done. Don’t be like me and put it off, make the appointment today! You’ll be very happy that you did.

Dr. Roshangar is so gentle and tells you exactly what she is going to do. Her entire office is calming , from the music to the chair. There has never been a wait and both my husband and I have been clients for over 10 years. Thank you Dr. Roshangar!

Excellent service. I feel always feel very comfortable. Very professional and personable staff. I love not having to wait. The office does not over schedule. When you walk in at your appointment time you go right in. My whole family has been to Dr. Roshangar and are very pleased.

For being a dentist they actually create a very relaxing environment. I brought my 2 year old as well and she really enjoyed it. They made her feel comfortable . Not only will me and my family be returning for all of our Dental needs but I know tell all my friends and clients who asked to try them out!

She made time to get me in quick, even though I was a new patient. Prices very fair.

I have been coming to see Dr. Roshangar for many years and have always had a five star experience. She is very kind and professional. Highly recommend her for all your dental services.

Dr. Roshangar and her staff have taken great care of our family’s dental needs for 17 years now. We wouldn’t go anywhere else and highly recommend her when friends or family ask.

Dr. Roshangar is such a wonderful dentist! My husband has been seeing her for years and when I met him I hadn’t been to a dentist in years. The dentist had always been not the best experience for me but when I decided to come in and see Dr. Roshangar that fear went away. She is so gentle, really cares that you are comfortable in her chair, and wants you to leave educated about your teeth and experience you had that day. I recommend this office to everyone and you would be lucky to have Dr. Roshangar as your dentist!!

X-rays, examination, cleaning and fluoride treatment done in less that 25 minutes gets me back to work before my lunch hour is over. Thank you.

Justin T. from Orange, CA (Source: Yelp)


Most pleasant experience ever with a Dental Office. The professional staff is very polite and caring.
I hadn’t been to the dentist in 5 years or so; it was most certainly time for a cleaning and check up. I had 7 new cavities, and several old silver fillings I wanted removed and composites put in. We were able to accomplish all of that in two 1 hour visits.
Excellent state of the art equipment. Gentle touch. Couldn’t be happier with Dr. Marjan Roshangar.
I also did the Zoom whitening here as well; fair price and improved my teeth by 9 shades. Brand new smile!
Such a great experience that I will look forward to my next general cleaning and check up.

Dr. Roshangar is an awesome dentist. She is caring and very gentle while working in your mouth! Her staff is friendly and efficient!

We love Dr. Roshangar. When I first moved to California I struggled to find a dentist that I liked and trusted until I found Dr. Roshangar. We have been with her for a 10 years now (including our 2 children). She is great with kids, and her office has a very laid back feel. She has many additional services available but NEVER pushes them whereas other dentists always seemed to be trying to up-sell me. You get none of that with her. She also has all the latest equipment making going to the dentist much more enjoyable.

I have been seeing Dr. Roshangar for a long time, I think it has been over 5 years. (I lose track of time). I always fee very comfortable and very welcome when visiting. I recently had an issue with a pain in my tooth and she was able to diagnose the issue and help me get it resolved. I would recommend Dr. Roshangar to everyone I meet

Sandra J. from Mission Viejo, CA (Source: Yelp)


I have gone to Dr. Roshangar for two years, and she has always been conservative in her treatment plan and also very thorough in her exams.  She even called my insurance when I was unsure if I had coverage, and we created a plan that would minimize my personal contribution.  She is truly a class act.  I am very selective about my dentists, and usually only see dentists affiliated with major universities such as UCLA or USC, so I was apprehensive about the change to a private dentist.  Dr. Roshangar came highly recommended from a family I knew from USC, and she has not disappointed.  Her rates are reasonable and she is very talented.

We no longer hate the dentist! Dr. Roshangar is the best dentist I have ever gone to and I hate the dentist and have avoided it for years. Her office is ultra modern and pristine and her staff is really accommodating and you never have to wait. She is super gentle and patient and will do research on how best to solve a problem without making you spend a ton. She has actually called and emailed me saying she found a better solution and a less expensive one. She has let my daughter come and play with the tools to get her used to the dentist and now my daughter loves the dentist. She is now in the process of rebuilding my husband’s mouth. Could not recommend this dentist enough.

Dr. Roshangar is great!! I’ve been going to her for years and she is always very friendly and professional. Her office is very up to date and clean and she always remembers you and details about you which makes you feel at home. I’ve recommended her to several other people and coworkers and all of them love her. Definitely a great dentist!

I used to hate going to a dentist. I have no problem going to the dentist now. I am very relaxed and the dentist knows all about my mouth and my sensitivity and she makes me comfortable. I have actually fallen asleep in the chair.

Dr. Roshangar has been our dentist since 2006. We live in Huntington Beach and still drive to Orange to see her. She and her staff are wonderful! She makes going to the dentist easier and carefree. Always with a smile on her face and even answers the phone and takes time for her patients 🙂

Wonderful person and yes, so gentle!!

The best dentist I have ever had and believe me, I have had many dentist. She has performed 3 root canals, crowns and bridges. ALL of them were absolutely pain free. She absolutely is the BEST in the business. HIGHLY RECOMMENDED WITH HIGH ENTHUSIASM!!!

My daughter began having all of her dental needs taken care of by Dr. Marjan Roshangar in 2011, when her practice was located on (different location), also in Orange, CA. I remember the visits being pleasant. The office was serene, the receptionist was professional, and Dr. Roshangar always greeted me kindly.

Over time, my son, my wife, and I joined our daughter in having all our dental needs met by Dr. Roshangar’s excellent service. Dr. Marjan has personally performed all of our teeth cleanings biannually for many years now. I know that our family is receiving the best of dental care.

She is accessible by phone, email, and has even accommodated an unscheduled visit when I have had dental related questions. The practice is now located on East Chapman Avenue, just a few blocks east of down town Orange’s traffic circle. The office atmosphere is serene, the receptionist is professional, and Dr. Marjan Roshangar still always greets me kindly.

My husband, daughter, and I have been going to Dr. Marjan Roshangar for the past eight years. We have been extremely pleased with her dental expertise, and her gentle service and care. She is always on time, unhurried, pleasant and professional. She does not recommend unnecessary work and is respectful of the patient’s decision.

Exceptional care and a gentle touch! Dr Roshangar’s office and staff is friendly, warm, and state of the art.  She is also honest and highly ethical. I am a dental professional and I highly recommend Dr. Roshangar!

Shirin A. from Orange, CA (Source: Yelp)


My husband and I have been going to Dr. Roshangar for years. And now even our little girl goes for cleanings I can’t say enough good things. First of all Dr. Roshangar is a very good dentist with a gentle hand. I have always been satisfied with her work. Second she is kind and interested in you as an individual. I always feel like I am visiting a family friend. Her office is modern, clean and very relaxing. Her staff is also kind and courteous. As an added bonus there is never a long wait . This office respects your time and never overbooks. So I can always rest easy that I will be able to get to work on time after my appointment.

I came to her with a root canal and a fear of needles, she was so kind and encouraging and walked me through the process. Referred me to an excellent oral surgeon and took care of my cap. I’m so glad I went to her.
