My boys and I love Dr. Castillo and very grateful for her care and attention.

Her ease with children was obvious. She had also taken care of my 3 year old and how she interacted with both was completely age appropriate. She is not only a great dentist, but understands child development and how to ease a little kids nerves and explain things to them and me. I cant say enough good things about her!
