Staff was extremely welcoming and Dr. Castellano took his time to explain everything from my X-rays to my plaque build up. Most thorough dental visit I’ve had for some time!

I was immediately impressed once I arrived at the office. It was very clean, the staff was friendly and informative – I knew I was in good hands. I met Dr Castellano and he (with the staff) explained my options and took great care of me. I’m thankful for the mailer and to have found such a great practice!

First time seeing Dr. Castellano…everything was professional, friendly and pain free. Catherine and Emily were great. Infact, my husband is going next week to see Dr. C for the first time. We found our family dentist and right here in Trinity.

After recently relocating back to the area, my family needed to select a new dentist accepting Humana. Found this place, and over the past few months, all three of us have seen both Dentist’s and all had greats results. Very happy to recommend! Their evening appointments are awesome, too.
