Testimonials

I am so happy I’ve finally found The Hills Modern Dentistry! Terrible experiences with my previous dentists have always had me dreading my trips to the dental office. From discomfort during my exams to unfriendly staff, and negligent doctors, it’s no surprise that I kept delaying my annual appointments and ultimately neglected my oral health. When I came to The Hills for my first visit, I was immediately impressed with the cleanliness of the office and the friendliness and efficiency of the staff.
Diane N. (Fountain Valley, CA)
As a former dentist, and now Dr. Don’s patient, I find him to be a very honest, caring dentist. Not an overseller, like so many dentists have become today. When I was a dentist I was very honest and conservative with my patients. I find Dr. Don to be the same way. Very conservative, honest, and skilled. All of my former patients who I have talked to and who now go to Dr. Don are very happy with him. Not a single complaint from any of them.
Steve T. (Laguna Hills, CA)
The place is very pretty and clean and I never have a problem with rescheduling appointments if something comes up. I truly look forward to my cleanings and seeing the entire staff. They are so efficient and with my busy work schedule, I truly appreciate that they offer a 7:30am appointment time. I highly recommend going here if you are looking for a new dentist!
Courtney T. (Laguna Hills, CA)
Very nice people, knowledgeable staff, friendly atmosphere, and helpful information! I love the fact that they let customers know what’s going on with your teeth, as well as try to create relationships with their customers. They are businesslike, yet they do not let that hinder how they relate to their clientele. Most importantly, they know what they’re doing, and they want you to feel secure and well-cared-for!
Olivia M. (Laguna Hills, CA)
I’ve been a patient here for over 15 years. The front desk is beyond helpful with handing dental insurance and scheduling appointments. I get my teeth cleaned twice a year and the hygienists always do an excellent job. Zahra is my favorite hygienist. If you’re looking for a professional dentistry with knowledgeable hygienists and dentists then this is your place. I highly recommend this dental practice to anyone and I’ll continue to be a patient here for many years to come.
Ryan B (Mission Viejo, CA)
I have been coming to this office for my dental work for about 15 years. Recently I had my crown replaced and a temporary crown while waiting for my permanent crown to be made. The temporary crown came loose the night before a holiday (4th of July) which I had big dinner plans for. Dr. Don came in to the office the morning of the 4th of July to re-cement my temporary crown so that I could still attend my event.
Dani B (Ladera Ranch, CA)
This is the best dentist office I have ever been to! Dr. Don and Dr. Vivienne are friendly, knowledgeable and extremely skilled. I have had two implants done in this office and Dr. Don did a great job. I’m so happy with the results. The office staff is wonderful. I highly recommend the dentist office!
Teri H. (San Clemente, CA)
So impressed! If your primary concern, when looking for a dentist office, is finding a staff that takes the time to check in with you every step of the way to make sure everything is being done correctly, explained well and that you are comfortable then this is your place! Thank you so much for making my dentist visits something I look forward to doing regularly again.
