Dr. Ernie Costello and office staff put patients first. Treatments and procedures are explained so that patients can make informed & educated decisions. I recently had a small cavity filled without Novacaine and was very pleased with the result!

Dr. Costello is a wonderful dentist. Extremely knowledgeable, great rapport with his patients, and so very friendly! He takes his time to explain things in a way anyone could understand. The staff at Costello Dental excellence is phenomenal to say the least...always accommodating and happy. They will always try to fit in am emergency no matter what. Both, Dr. Ernie and John Costello will take emergency calls on their cell phones.

My wife and I have been patients of Dr. Costello for five years. He is kind and very professional in his manner. I recommend him without reservation.

I have been going here for over 10 years. I highly recommend going to their office. Their staff are great and Dr. John and Dr. Ernest always make sure my visits go good. They take their time to make sure everything is how it should be and make sure you're comfortable. They are awesome at answering any questions you have.

I trust Dr. Costello to provide the quality care I have come to expect through over 40 years of relying on this practice. I was glad when Dr. Ernest first joined the practice as I knew I could continue to count being well cared for. I travel an hour one way because I trust Dr. Costello and the entire staff.

After 19 years of being a patient at this office I thought I would try somebody else ( health insurance reasons only). I went to see another dentist and was back at Dr. Costello's office in no time!!

Yikes, been going to this practice since 1994! Everyone is very efficient, friendly and in the know with up to the minute dental practice and procedure.
in Mount Prospect, Il |
Doctor "Ernie", as his patients call him, is skilled and caring. I've been extremely impressed by my experiences with him and the facility. He takes time to explain things and is detailed in his work. Can you believe anyone would say they like their dental experiences, but yes, Dr Costello helps create a comfortable and caring atmosphere and one in which you know that you, the patient, will be getting the best of the best in dental care.
in Round Lake, IL |
Love Costello Dental and have been a patient for many, many years. Doctors and all office professionals treat the patients as family. Newest technology always available and interest in patient care is outstanding.
in Buffalo Grove, IL |
Dr. Ernest Costello is an exceptional dentist who has a genuine compassion for people. He is as patient as can be with me. He fully explains everything and makes sure I am comfortable and pain free, be it a root canal, extraction, crown or bridge. The entire staff is as fabulous!!!

From regular visits to an implant, I have only had great results from Dr. Ernie Costello and all their employees.
