Great service.  All of the below reviews are right on.  This guys goes above and beyond and there is no hard sell (like other offices) of services that are not needed. There is a long wait to see him and there is a reason why.  HE IS GOOD

The location is great but if you are unfamiliar with the general area then you may show up at the wrong building.  There are several building that look the same in the general area.  The actual location is great with plenty of parking, just keep in mind the fast moving traffic on the main street adjacent to the location.  Once inside the office is super clean with a recently remodeled look to it.  The crew (Kathy+Norma) is always really friendly and knowledgeable as well.  Mani is a professional and trustworthy dentist that is confident in his work ethics.  I was recommended to Mani by fellow coworker when I was 16 when I worked and lived within miles of his office.  I now live roughly an hour away and continue to make the drive because of the expertise in which Mani and crew present, even as my wife urges me to change to the dentist which is about 5 minutes away from the house.  I used to get cavities and root canals completed here, if I am not mistaken I think Mani only does cleanings now. Would definitely recommend!!!

Looking for a good dentist is no easy task, and I feel like Dr. Mani Zarnegar fits the bill. I found out about his office through my boyfriend and his family, who have been seeing him for over 10 years. His office staff is very warm, friendly, and helpful.  There is always someone available to answer the phone, and they are great about calling you to remind you of your appointments. I really feel like they care about your treatment and well-being. In addition, they are very accommodating to their patients’ specific needs. As a new patient, I discovered I need periodontal surgery, and would require a cleaning before I can proceed. His office went out of their way to schedule me with a cleaning with only 2 days notice. What service! As for Dr. Zarnegar himself, he is a very warm, personable, and is very competent when it comes to dental care. He explains what you need clearly, without judgement passed. He has top of the line equipment, and his procedure chairs even have a massage feature. He also encourages you to listen to music with an iPod he provides while he works. It really helps to take the edge off. There is also nitrous gas provided for added comfort. He does all of the work himself, including cleaning, and he is very gentle and efficient.

I’ve been going to Dr. Zarnegar almost my whole life and he is truly the best. I moved to the East Coast a few years ago and have yet to find a dentist that compares. Years ago, I requested that Dr. Z  put in a few veneers on my front teeth to help with spacing and every dentist I’ve gone to has told me the work is perfection. On that note, he never suggests or pushes unnecessary procedures on people and his pricing is very fair.

Dr. Zarnegar has been our family’s dentist for a decade. He knows us and remembers us even though we only see him for visits twice a year. We love our dental visits here. Even after I moved to Los Angeles I kept going to Dr. Z’s office for my regular teeth cleaning visits. The staff is so nice and the chairs are the most comfortable. You have a choice to listen to music on headphones during your visit. They really try to make you feel as comfortable as possible.Something outstanding about Dr. Zarnegar is that he does all the work himself even though he has a dental assistant/hygienist. Even if you’re going for a cleaning, Dr. Zarnegar is the one who is polishing your pearly whites. I don’t know any other dentist who does that. He is truly good at what he does–I’ve never felt discomfort. He’s really honest, too. I’ve never had to pay for unnecessary treatments or procedures. I highly recommend him to you and your family.

My entire family has been seeing Dr. Zarnegar for the past 23 years.  I started seeing him as a sophmore in highschool and I’m 37 years old now.  But I don’t think he’s aged a single day since then.  He knows everything about my mouth and takes really good care of me.  No cavities!  I recently started sending my son (age 4) to him and he does really well with little children.  I highly recommend him.

I’ve been a patient of Dr. Zarnegar for a few years now, and after having been to several other dentists, he, by far, is the best!  He is kind and caring and gives you his undivided attention and never makes you feel rushed.  Kathy and the front desk and his assistant (Rosa?) complete the team to make a truly patient-centric experience. I had a dental emergency while out of town, and he was able to see me the day I returned and quickly referred me to a specialist for the needed treatment.  This was the second specialist in the past year that he has referred me to, and both were top-notch as well. Thank you all!

My husband & in laws have been going to Dr Zarnegar for at least 25 years and I’ve personally been a patient for over 10 years. He is an honest, caring and kind doctor. He is an extremely great dentist. I highly recommend him!

Dr. Zarnegar has been my dentist for my entire life. As a kid, I actually looked forward to going to his offices as they have great games in the waiting area, a huge selection of CDs to listen to during your cleaning, and really cute cartoons on the walls. In addition, I have always been impressed with the friendly, knowledgable, and helpful staff. Dr. Zarnegar is very skilled… I’m judging this based on the fact that I have never had any problems with the 7+ fillings he has done (I have an insatiable sweet tooth). He is very good at adminstering the novocaine… he did this cheek-jiggling thing so you don’t actually feel the needle go in. For someone who is pretty nervous about needles, this was fantastic.
Even after I moved from CA to CO, I continued to schedule my cleanings when I was back home; however, now I live in MD and won’t be able to make it out there enough. I’m nervous to find a dentist out here because I know I’ll be disappointed in comparison!!

Mani Zarnegar was my dentist in the 1990’s and did a ton of work on my teeth.  In 1995, my husband and I relocated our family to New Jersey.  For the first several years, I did not even bother to find a new dentist in New Jersey.  Instead, I planned my visits back to California every 6 months so I could go back to Dr. Zarnegar.  I couldn’t keep that up forever, of course.  Over the years, I have had a number of different dentists on the east coast of the U.S., and none have compared to Dr. Zarnegar.  He is by far the most personable and skilled, and is also an extremely nice guy.  I introduced my best friend to Dr. Zarnegar, and she has continued to drive all the way from Huntington Beach for her checkups because he is just that good.  Anyone looking for a dentist in the area should definitely give Dr. Zarnegar a visit.

Dr. Mani Zarnegar is, with-out-a-doubt, the best dentist one could ever ask for.  He’s been my dentist for over 11 years now and not once have I had a bad experience.  He’s friendly, personable, professional, and most importantly, he knows what the heck he’s doing!  All procedures are explained thoroughly and he uses his high-tech equipment to make sure his patients understand what’s going on with their teeth. He does everything possible to ensure you feel nothing uncomfortable while he works, and he offers iPods with great music along with massaging chairs!Dr. Zarnegar’s staff is extraordinarily courteous and professional.  His assistant, Rosa, is topnotch and always makes me feel comfortable when I arrive.  His receptionists are very friendly, and have never once forgotten to give me a 24 hour reminder — In fact, they’ve given me the opportunity to come for an earlier appointment on multiple occasions if it’s more convenient for me.  Topnotch service, indeed!I’ve sent several friends, family members, and colleagues to his office over the years and by unanimous consent, they’ve all concurred they’ll never go anywhere else!  Dr. Zarnegar has even sent me a card of gratitude, signed by his entire staff, each and every time I’ve referred somebody to his office, thanking me for my trust!  What more can I say?  If you need a dentist in the OC area, look no further!
