Our patients leave smiling
I’ve been a patient here for about 18 months now. I have had cavities filled, wisdom teeth removed, and sudden tooth pain examined. I used to be terrified to visit the dentist. After 8 years I finally went to this place. To start, the staff is amazing. Just yesterday I was in the waiting room listening to a receptionist (I believe her name was Sherri) give a first time appointment and step b…

I have already referred your office. There is not a “rushed” feeling. The staff, from the moment you are greeted, until you leave the office, are friendly, professional, caring, and courteous. They answer any questions, and they discuss options, as well as possible downfalls, without “sugar coating it.” I’ve been to numerous dental offices since moving east in 2012, a…
When my 12 year old grandson’s permanent front tooth fell out my daughter and I scrambled to figure out what to do. We called the hospital and walk-in ER, our primary dentist and other dental offices, and, of course, searched the internet for answers. After reaching voice mails and getting conflicting information I drove him to Dental One Associates. I had never been there before, but since…
Always excellent service.

Friendly caring staff. Dr Whang made me feel at ease throughout the process of my root canal. Didn’t get her assistants name but she was also top notch.
Dental One Associates of Westminster has been awesome to be a client of. The orthodontist Dr. Segafi was able to fix my overbite and middle allignment and I couldn’t have chosen a better orthodontist. The front desk staff is also wonderful. Sherrie always took her time to reach out to my dental benefits whenever there was an issue and always provided friendly service whenever I had questions.
I have been a patient of Dental One Associates for several years. They are always wonderful to work with and the Dentists and Dental Hygienists are always very friendly and take their time to do a thorough job. Sherry is always so friendly and helpful. A pleasure to deal with when scheduling appointments and receiving quotes for dental work needed.

Hygienist Jenny, who I did not know, was excellent. Not only was her “chairside manner” outstanding, but she was very professional and knowledgeable. She is the first D.H. who suggested I use a tongue scraper. She meticulously cleaned my teeth. I like her. Regarding Doctor ‘K’, he’s the greatest.
