Dr. Koroni saved me from a lot of unnecessary dental work. I came to him for a second opinion after another dental office gave me an outrageous treatment plan, and he took the time to show me exactly what my teeth actually needed. It was way less than I was told at the other place. I've been a patient of Dr. Koroni…

It was way less than I was told at the other place. I've been a patient of Dr. Koroni for three years and counting because of the trust I have that I'm going to be treated well.

Our family was a regular at Dr Durusky for more than 8 years and just because I have denied X-rays for my child a few times due to medical reasons, they have abandoned us without any proper notice. I sent them a request for reconsideration of their decision, but I received a very cold and inconsiderate response. Inspite of explaining to them about our medical situation, they kept pressurizing us for more X-rays, which made me feel very uncomfortable. I wish they at least appreciated our business for 8+ years and had tried to communicate better. My fillings were also done very badly, which fell off in less than 3 months. I feel so cheated and mistreated by this clinic.

I always have a great experience at Cornerstone Family Dentistry. Dr. Durusky is the absolute best! Very knowledgeable and friendly. Deanna, dental hygienist, does an excellent job and is such a kind person. So happy to be under their care. I love this practice and highly recommend it.
