Our family loves Dr. Khajavi and her entire staff! We have been coming here for over a decade. She always takes care of us, from a healthcare standpoint, but she is also very caring, kind, and friendly. I can’t recommend her enough and we’re so grateful to have found her many years ago for our family’s dental needs. Thank you!!!

I've always had anxiety going to the dentist due to bad genetics and being shamed at every previous practice I visited. But not here! I would be willing to drive hours to come here just to feel safe and comfortable. 10000% recommend!

I was referred by my mom and it was the best decision! I tried other doctors/dentist and they did not do a good job, and tried to scam me. Fortunately, Spectrum Dental did an amazing job making me feel comfortable and taken care of! It took me over 4 years to get my wisdom teeth removed because of how scared I was and they helped me quickly, had an appointment and within the next week I was able to get them surgically removed. Love all the staff, they were helpful, wonderful and caring people! I was so nervous because I never gotten put to sleep or never had surgery but it was a smooth and easy procedure and again, the surgeon, nurses and receptionist were so amazing! You can tell the doctor and surgeon cares about their patients and explains everything in a clear detailed way which I’ve never experienced. Huge thank you to everyone at Spectrum Dental

This review is specifically for Olivia at the front desk who called to yell at my mom after hours about my review - is that how you treat patients? These people know what they did and don’t want you to know about it so they can do it to you too. You should all be ashamed of the lack of professionalism your staff provides at Spectrum Dental Arts and how dare you try to cover your tracks. Do better

I recently started going to Spectrum Dental Arts and I have to say this is by far the best dental office I have ever been to. From the moment you walk in you are greeted with such warmth and professionalism. Olivia at the front desk is absolutely amazing. She was the first person I spoke to when I called to make an appointment and she made me feel so welcomed right away. She took the time to explain everything clearly, gave me an estimate of the treatments I needed, and really made me feel like she cared. That first impression is what made me choose this office and I am so glad I did.

The dentist is wonderful. She is so kind and makes you feel completely comfortable during the entire visit. She constantly checks in to make sure you are doing okay and that goes a long way in easing any nerves. Her assistant is also incredibly nice and together they make the experience smooth and stress free.

The entire team at Spectrum Dental Arts truly goes above and beyond. They treat you like family, not just a patient, and that makes all the difference. If you are looking for a dentist who is caring, professional, and genuinely interested in your well being, this is the place to go. I highly recommend them to anyone.

I am completely satisfied with my experience at Spectrum Dental. The office is immaculate and beautifully designed—especially striking during sunset, when the natural light enhances the warm, earthy tones, creating a serene and welcoming atmosphere.

The customer service is outstanding. From the moment I arrived, I was treated with the utmost care and attention—truly a red-carpet experience. The doctor is exceptional, and their professionalism clearly sets the tone for the entire team. The staff reflects that same standard of excellence in every interaction.

I highly recommend Spectrum Dental. They consistently operate at the highest level of quality and care.
