Very expensive and lousy service. This guy failed to treat a few problem areas that coud of been done in one treatment so that I kept on having tooth pain -- this after he charged me a lot of money for one tooth crown. He needlessly gave me stress and anxiety. I think he wanted me to keep coming back so that he could charge me more. Another dentist I visited shortly after Dr. Hernandez was surprised why Hernandez left an open filling and cavity that they easily corrected and which stopped the soreness in my mouth and which turned out was most of the cause of the soreness in my mouth. Has a degree from some Foreign Island University I never heard of. Avoid!
