Very friendly staff! The dental hygienist Judith was wonderful - she's precise, efficient, and really took her time not only cleaning my teeth, but also explaining what she was doing and what I could be doing better to maintain maximum oral health. The dentist who checked my teeth was also very efficient and did not seem rushed at all. She took the time to listen to a concern I had and made sure to address it with me right then. What a great team!

The staff is very patientand aw well as professional. The office atmosphere is nice aIso. I was very anxious and apprehensive going into a minor surgical procedure but Dr. Collier and her assistant were awesome! All fears were assuaged, I was comfortable, and the procedure went off without a hitch! I'm super grateful!

Dentist Dr. Dulan extracted a tooth after I went to another dentist who said I needed an oral surgeon dr. Dulan extracted my tooth in less than I minute without pain. I would recommend spectrum dental and Dr. Dulan made a usually frightening experience one that was painless and easy. I used to dread going to the dentist but Dr. Dulan made it a breeze. I would highly recommend them.

I left the dentist office a few minutes ago. I had a nice experience. The staff was kind and caring and the dentist was very professional. Everyone was very welcoming and the overall positivity made me feel comfortable. It was my first time at this dentist office and I was able to get done what I came in for plus a cleaning too.

In a world where customer service and quality of service seems to be a thing of the past. I am here to TRULY say, my experience at Spectrum Dental yesterday was totally the opposite. I was treated like a kid as if it was all about me and the things that would make me happy and feel comfortable. I have to admit, I am a big kid when it comes to dental work. Dr. Dulan and her assistant made me feel like. I could have gone through open heart surgery and all she did was stuck me a couple of times to numb me. My point is that, they were not only gentle they were very genuinely caring. For that, I am so very grateful! You have to be good, no, great to convince me that it's okay to get a needle. Thank you for making my visit a pleasant one. You guys are the BEST!!!!!!!!!!! Rodney

I visit twice a year for exrays and cleaning. Judith, the hygients does an amazing job overall. If you have a fear of going to the dentist after one visit you wouldn't have any fears no more.Customer service is great . Very little wait time and once your done you can't help but to smile every chance you get.

Dr. Collier and her associates have been our family dentist for about 15 years. Her staff is always professional and friendly and since we have been regular patients for so long, they even ask about my sons when they are not with me. She said either she was good or I was tired. I recommend Spectrum Dental highly and look forward to this practice always servicing our family's dental needs.

Initially went to another dental office who attempted charge me a huge fee and appeared unwilling to work with existing dental coverage. Spectrurm Dental took time to talk to me, worked with my insurance provider, and developed a plan to deal with a complicated dental procedure. The oral surgeon was also present at the time of extraction in case the post could be implanted on the same day. The post will be implanted later but it was nice to see that they covered all bases.

If you need an extraction done, this is the place to come get it! It's quick and nearly pain-free. Dr. Caldwell is very good at what she does.
