Very professional, clean, courteous. I'm not a dental price wiz, but even with my dental insurance his prices out of my pocket are still high. I will be shopping around before I get any work done. If money isn't an issue for you I would highly recommend.

I would highly recommend Dr. Costello. He was friendly, thorough, and listened to all my concerns. The office staff was great too. They came up with a treatment plan for me which clearly showed how much my insurance would cover, and how much I would have to pay. Then they went over it with me, gave me a few options, and even a small discount. Definitely one of my better dental office experiences! They even have tablets attached to the light fixture so you can watch Netflix while you get your teeth cleaned. Very helpful if you're the anxious type.

I went to visit Dr. Ngo for an initial consultation. I told her my history of tooth grinding - that I had worn off a lot of enamel on my teeth (which left tiny brown spots on molars that sometimes looked like cavities) and need a new mouthguard to prevent grind. I also shared that I may need to get a filling fixed on my molar. I did not feel as though she listened to this history and instead told me I had approximately 5 cavities, needed a root canal, and needed to get my wisdom tooth pulled. I went to my former dentist to get a second opinion. He shared that I only needed a filling repaired and encouraged me not to get my wisdom tooth pulled.

This was my first time seeing Dr. Costello and he was fantastic. Short wait and one of the best cleanings I've had in years. I just moved to Philly and thankful for using Zocdoc to find a great dentist. My wife will be scheduling her appointment next.
