 Trustindex verifies that the original source of the review is Google. I had an excellent experience at my dental visit today. The dental hygienist was wonderful—very attentive, efficient, and thorough. I arrived feeling quite nauseated, and the entire team was extremely sensitive to how I was feeling. They offered me water, stopped the X-rays when they realized they were making my nausea worse, and even played meditation music to help me relax, which really helped. Dr. OEI was also very caring, conscientious, and attentive. I truly appreciated the compassion and flexibility everyone showed while still providing excellent dental care. Great experience and a wonderful team!

 Trustindex verifies that the original source of the review is Google. Becoming a patient at Colony Dental Care was the best decision I've made. Dr. Oei has done bridge work on me and a root canal, all to my satisfaction. The staff explains the insurance coverage and my out- of -pocket cost thoroughly.
