Our Patients Say

Outstanding customer service because everyone is so friendly here... My family and I have been coming here for about 15 years and we have NEVER had any negative experiences. Today I had the awesome results of Dr Castillo using a LASER machine to remove 3 cavities, which meant NO numbing shots. This LASER technique made for faster results for my BEAUTIFUL SMILE...Dr Castillo and his team are truly the BEST...🤩

Dr. Castillo did an implant in 2015 on one of my front teeth everytime I go to the dentist they compliment his implant. Today is the first time I had an issue. A screw came loose and another denist was able to go in and replace the screw (screw that holds the crown to the implant). Dentist said this was a common occurrence for implants. While he was doing this he took his time to tell me what a GREAT job that had been done on this implant. Thank you Dr Castillo!

I recommend the new laser dr. Castillo has in his office. Didn’t have to worry about a needle in my mouth. The new laser is no pain at all and a quicker process to fix a cavity. I really recommend it.

I loved the service provided and the follow up as well. The whole team helps you, getting an appointment and being received in a timely manner is appreciated. I had a bit of a difficulty on a surgery and the after care was wonderful, they made sure to ask me how I felt and how everything was healing. I am very picky about doctors and here, I am glad to say that I will come back.
