Been going to Dr. Castellano for many years, but I would take my son to a pediatric dentist over an hour away because of his fear of dentists. Dr. Castellano saw my son, made him feel at ease, takes his time to explain everything. He still doesn't like going to the dentist but at least now its a little less stressful.

Dr Castellano has done extensive work on my very soft teeth over the past 25+ years. He is a perfectionist who will not settle for anything less than a perfect result. He just finished putting veneers on my two front teeth and they look terrific!! I couldn't be happier with the results.
Dr. Castellano performs virtually painless procedures and takes great care that his patients are comfortable and at ease. I would highly recommend him!!!

Betsy P.

Dr. Castellano is the best dentist I know! And I should know, I've been going to him for over 20 years.

Mel C.

I have been going to Dr C for close to 20 years and will never consider going to anyone else. He takes the time to explain every procedure in a way that I can understand.. He is patient and empathetic and just a great human being. Over the years, Dr. C has added so much to his practice to the benefit of his patients including (more recently) doing implants from start to finish. I would remiss not to mention Jessica and Wilma who are just wonderful.
