PW on 06/21/2017    My experience with Dr. Roshangar on Monday, June 19, was very professional, caring, and very knowledgeable when it came to the root canal procedure she performed on my ailing molar. Dr. Roshangar called me the following day to check on my progress. I'm doing much better on the third day after the root canal and no longer have any pain. Thank you very much, Dr. Roshangar
PV on 06/21/2017    Always so friendly and professional. My last visit I had to bring my 2 kids with me and they were extremely accommodating. While I had my teeth cleaned the very friendly receptionist kept my kids entertained. I've never experienced this kind of service anywhere else.
RM on 06/21/2017    There is never a wait with Dr. Roshangar and she truly does provide gentle dental care.
Anon on 06/15/2017    I absolutely love going to the dentist as long as it's here! Everyone is so friendly and kind. There is no prodding or poking without consent of you and it's very soothing!
Anon on 06/15/2017    Wonderful!
Anon on 06/15/2017    Excellent!
DH on 05/26/2017    Very caring. Explained what was happening step by step.
EJ on 05/19/2017    Marjan is amazing ! I have never had a dentist take care of me so well. She was patient and gentle with me. She is sweet and genuine, something that all previous dentists of mine did not have. Thank you Marjan!
KA on 12/29/2016 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.
BS on 11/08/2016    Dr. Roshangar provided exceptional care when I came to her for a second opinion. Dr. Roshangar recommended onlays instead of crowns for two posterior teeth that were cracked. Not only did it save me money but it preserved the teeth! Great communication and pain free dentistry, what more could you ask for. She also volunteers at local clinics which is great for the community.

JT on 09/08/2016    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.
DQ on 04/23/2016    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.
EB on 07/13/2015    Dr Roshangar is a phenomenal dentist and I hate going to dentist lol. She is comfortable and caring.  Her office off of Chapman is amazing. 
I have been going to her since 2006. I live in HB now and still go over to her with kids.  They love her as well....
LN on 09/06/2013    Dr. Roshangar moved off of Chapman and Pine. The new office is awesome! Everything is very new and modern. Really looks great. Much more open feeling. Plenty of parking and easy to find. She even has new chairs that give you a light massage while you are getting your teeth cleaned or whatever procedure you may be there for. The X-ray machine is hidden away in a cabinet, that you would never think it would fit it. Not only that, she has a new assistant that is seriously the best one yet. I had to get x-rays done and she was the only one that didn't have to retake x-rays because they weren't right the first time. I've always liked coming to Dr. Roshangar, but now I do even more! She always seems to remember what you talked about the last time you visited. Really makes you feel at ease. I highly recommend her!
JM on 07/26/2012    Very friendly, quick and gentle. Would highly recommend!
SJ on 12/05/2011    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.

MD on 08/05/2017    I recommend Dr Roshangar highly for dentistry. She is kind, caring and skilled. She does not push unnecessary dental work on you as has been my experience with other dentists.

SH on 07/31/2017    This biannual cleaning was especially meaningful. One of my fourth-grade students commented on my brown teeth. After the cleaning, I was so pleased when I looked into the mirror and saw white teeth again! I drank a quart of black tea every day, but no more. Thank you doctor Roshangar for removing those unsightly tea stains.
MM on 07/28/2017    Dr. Roshangar is very honest, professional, and personable. She explains every procedure carefully and makes sure her patients are comfortable. She really is wonderful!!
