I want to say that Dr. Sierra is an excellent Doctor. She is very professional, pleasant and a caring doctor with all her patients. She is a beautiful person inside as she is outside with a pleasant attitude. Every time that I have had an appointment with Dr. Sierra it feels like I am in a spa and not at a dental office. Dr. Sierra's office is very clean with a relaxing atmosphere. She makes it hard for her patients to leave her office because she makes you feel very comfortable. I would highly recommend Dr. Sierra to anyone who is looking for a dentist. Thank you, Dr. Sierra
