Costello & DeHart Dental Excellence 1510 North Arlington Heights Road, Arlington Heights, IL 60004

"I decently chipped my two front teeth last week and though the office was closed, Dr. DeHart responded fast and was able to fix my teeth within hours. Everything was done very gently and all of my questions were answered thoroughly, which meant a lot to me especially in my panicked and injured state. My teeth look amazing and I have never had anything but amazing experiences here. Thank you again!!"

"I don't usually leave reviews but my recent experience at Costello & DeHart left me with no choice. I work from home year round but this week was the ONE week where I had to go into the office for face to face meetings all day long. The night before work, right before bed, I accidentally chipped my front tooth. Bad! Very noticeable. I went in to see the dentist first thing in the morning, 8AM, no appointment. I had to be in the office by 9AM. Not only were they kind enough here to take me in without appointment but they fixed my tooth, good as new (not to mention they had to do it twice because I broke the first one when biting too hard on the paper test, and they only charged me for one). I made it into the office ON TIME and with a confident smile. Not only are they awesome at their jobs here but every single staff member I've ever met is super nice and personable. If you are not happy with your current dentist I cannot recommend these kind folks enough. THANK YOU COSTELLO & DEHART! You are life savers!!!"

"Great dental office! I have been going to Costello & DeHart Dental Excellence since I was 8 years old. I first had Dr. Costello and then Dr. Ernie. I've always hated going to the dentist but they always made an easy experience. I ended up moving to Oklahoma April of this year and they set the bar so high that I am having trouble finding a new dentist out here."

"This was a professional and expert dentist experience that had had a profound impact on my life. I was treated with upmost patience, kindness, and professionalism. I was given time and care that I would’ve otherwise never been able to afford. This was much needed, but not required help to a veteran. It absolutely has changed my physical health and improved my life for the better. I’m beyond grateful for the Dr. J, his partner and his amazing staff. I’m still in awe and so appreciative of the care I received. I would recommend this practice to absolutely anyone and feel confident that they would receive the best of care."

"I have been seeing Dr. Costello for the better part of 15 years and I have not met a more friendly staff. It doesn't feel like "going to the dentist". The staff cares about each individual as more than just a patient and it really shows. The appointments are fairly quick and I am not usually there for more than an hour for a regular cleaning."
