Check out what some of our happy patients are saying about us:

I’ve been coming to Dr Dornan for over 15 years it’s always a pleasure to walk in and be greeted with friendly smiles and prompt service – (trust me you won’t have time to just sit in the waiting room reading through an assortment of new magazines they’re ready for you at arrival time!) All 3 of my kids drive down from LA for their annual cleaning, X-rays and checkups not one complaint they’ve been patients of Dr Dornan since childhood. Wish I could give more yelp stars and tell you more about her wonderful staff but you’ll just have to make your own appointment and see for yourself

Great team! Felt very taken care of and had many confirmations about upcoming appointments. I appreciate the use of technology that they have instituted. Everyone is really nice and genuine- it’s not often you look forward going to the dentist but I felt that way with how well they took care of me.

I’ve been going to Dr. Dornan for years. She’s friendly, caring, and always puts me at ease. I never feel afraid about going to the dentist. I know I’m in capable hands. My whole family goes to Dr. Dornan. Even my kids won’t go to any other dentist. For a little while, after I changed jobs, I also had to change dentists, since my insurance required that I see a dentist within the network. I was not very happy. I went to the dentist that was assigned to me. He was ok, but not like Dr. Dornan. After a little bit or research, I found out my new job also offered my previous dental insurance, and so I was able to return to Dr. Dornan! Yay!! Now I’m so happy once again with my favorite dentist. I would recommend her to anyone who is looking for a great dentist with an awesome attitude. It’s obvious she loves what she does.

Since having a “scary dentist” as a child, I have always been nervous at the dentist. But Dr. Dornan makes me feel comfortable and confident that the process will be quick and painless. And it always is. I have been her patient for 26 years now!!

I had an tooth break last week and I wasn’t sure if it was a crown or the tooth. I placed a call to Dr. Dornan and she called me back. She was able to get me today (Monday -10/2/2017) and determine that I actually broke my tooth and I will be getting a crown. As always Dr. Dornan and her staff are awesome and a life saver…..

The hygienist Michelle and Dr. Dornan do do excellent work.   Dr. Dornan and her team are the best in the O.C.

Bobby J. from Santa Ana, CA (Source: Yelp)


We’ve been seeing Dr. Dornan for the past year. The office staff is extremely helpful and friendly. The hygienists are very knowledgeable and do a great job cleaning teeth. Dr. Dornan and staff are the best.

Great Dentist. Very thorough and efficient. Staff is awesome too. Will continue to recommend Dr. Dornan to everyone I know who needs a Dentist.

I had a slight emergency and the front office got me in to see Dr. Dornan. She was very reassuring in her diagnoses and I left her office very happy. I really appreciate her fitting me into her busy schedule.

Tennille G. from Orange, CA (Source: Yelp)


Love this office!  My whole family goes to Dr Dornan and we always have a very positive experience.  Dr. Dornan is thorough, honest and trustworthy. Lisa the hygienist is amazing!

Jeff B. from Irvine, CA (Source: Yelp)


Have had 2 appts. Hardly waited in reception area and they were accurate with how long appts would take. They also don’t overcharge for their services. Very pleased and would definitely recommend them to anyone.

Best dental office ever! Kind, supportive staff. Conservative and gentle dentists and dental hygienists. An easy 5-stars!

M W. from Orange, CA (Source: Yelp)


Dr. And staff are friendly, professional and make sure your needs are addressed. My approval for treatment still has not changed me in when I arrived for my appointment. They called my insurance company, followed up and got the approval so I did need t have to wait or make another appointment. That is what I call excellent service!

Donald C. from Newport Beach, CA (Source: Yelp)


Dr Dornan and her team are the best. Great environment good prices and great work. I trust my smile to her and you should too.

Tom R. from Foothill Ranch, CA (Source: Yelp)


I’ve been a client at Roberta Dornan’s office for at least 15 years.  Their service is great.  I have sensitive teeth, and like many people I used to dread a visit to the dentist.  The folks at this office, however, are very client-focused, friendly and attentive.

Tamara D. from Orange, CA (Source: Yelp)


Dr. Dornan is very caring and thorough! She has been able to relieve my TMJ pain! Thank you so much!

Pete G. from Tustin, CA (Source: Yelp)


Dr. Dornan has been mine, and my families, dentist for over 30 years. She is superb and her office staff is excellent. Never a wait, friendly office environment, and treat you like a person vs. just a patient. Couldn’t recommend more highly!

Dr. Dornan is professional yet very personable. She made a mouth device to treat my sleep apnea as I cannot tolerate a CPAP. I have had several crowns replaced since the device was made and I see her periodically to have it adjusted. I highly recommend her and her office staff.

 Olivia C. from Huntington Beach, CA (Source: Yelp)


I’ve been searching for the perfect dentist for years. Dr. Roberta doorman is amazing. I love having a full female staff everyone is very friendly. They’re always running on time and I never have to wait more than five minutes to be seen. I never feel like they’re rushed during my  visits. Also they’re not trying to sell me a different things every time I come in like supplements or gadgets. I don’t mind getting my teeth cleaned now, they’re very gentle with my TMJ issues I highly recommend them to everyone.

My wife and I have been patients since 2001/2002. Prior to this, we changed dentists very often because they proved untrustworthy and seemed to merely try to squeeze out every penny from our wallets. Here with Dr Dornan, we finally met a friendly and professional dentist who looked out for our teeth and health above all. She has a friendly staff and a clean office. The waiting room is quaint and pleasant. The patient stations dont overly smell clinical. I havent had a cavity for almost 10 years and I believe it has a lot to do with Dr Dornan and her staff of hygienists. We are going to have our first child due in december and we know his teeth will be taken care of here 🙂

Sacha M. from Newport Beach, CA (Source: Yelp)


Dr. Dornan is extremely knowledgeable, very kind, and completely professional, and the same can be said for her equally amazing staff.  Appointments always begin on time, everyone there is happy and personable, and you can even watch crazy DVDs about animals while you get your teeth cleaned.  No joke – I actually look forward to going to the dentist now!

My experience at Dr. Dornans is always superb. This particular visit I was in pain and they got me in right away. I always feel valued, and that I’m getting the best dental care possible. I recommend Dr. Dornan’s office to all my loved ones!

Dr. Dornan + staff were great! I had to move my appointment back slightly and they were able to meet me half way. Staff is friendly and service was quick.

J R from Orange, CA (Source: Yelp)


I love this place and I HATE going to the dentist. Lisa who cleans my teeth is so kind and friendly and does a great job. Also Dr. Dornan is great. It never hurts if and when I have to have work done. I definitely would suggest going her if you have any issues or anxiety of going to the dentist.  They all have a very soft touch and the front of the office is also fantastic. Who else gets a text reminder about your dentist appointment

Marissa L. from Garden Grove, CA (Source: Yelp)


I have only been coming to Dr. Dornan’s for about a year but they are amazing!  They always work with my schedule even when it can get a little hectic. They are always extremely nice and have plenty of toys for my daughter to play with and keep her entertained while I get my teeth cleaned which is nice. Soon she’ll be seeing Dr. Dornan as well.  They definitely made me feel very welcomed to their practice.

Barbara S. from Santa Ana, CA (Source: Yelp)


Best dentist in town.  I highly recommend. Great office staff and they really care for you and treat you with kind hands

Madelaine S. from Irvine, CA (Source: Yelp)


My entire family has gone here for close to 20 years.  My son lives in Northern California, yet he chooses to get his dental work done here when he comes down to visit me.  They’re really great.

No frills Dentist. Really like her skills and not proposing things that aren’t necessary.

As always, the most positive experience one can have while visiting a dentist. 🙂 Been coming here for years, intend to continue.

Jean Louise J. from Santa Ana, CA (Source: Yelp)


Best. Dentist. Ever. I am so glad I found Dr. Dornan when I moved here 15 years ago. The fabulous hygienists and the staff make the experience of visiting the office something I actually look forward to.
