Rose did a great job - she is an excellent dental assistant. She is very professional and expert at what she does and has a wonderful soothing personality that keeps the patient amused and relaxed.
Being someone who has childhood trauma with dental work, I have been very happy with Dr. Lee and the Advanced Dental Arts team over the years. A special call out to Trinity who did my dental cleaning today. She was so nice, friendly and compassionate with me being very anxious about any dental work. She is amazing!
