Hear What Our Patients Are Saying…

  • I have visited Dr. Deneka's office, now Cornwall Dental Arts for over 26 years.They have always provided my family with superior service with state of the art dental equipment and techniques. The staff go above and beyond for each and every client. I have never waited more than 5 minutes pasted my scheduled appointment time. I would highly recommend Cornwall Dental Arts to anyone looking for an honest and caring dental team.
    —Steve Branchaud
  • My husband, myself and our son have been patients of Dr. Deneka for over 25 years and we have been more than pleased with the service. Dr. Deneka and his team are extremely professional, friendly, knowledgeable and competent. We have recommended his office to our friends and would never hesitate to praise his staff. Kudos to Dr. Deneka, you truly make a wonderful difference not only to the community but in people's lives. Thank you.
    —Susan Lee
  • Dr. Deneka is one of the best and honest dentist that I ever went to. Had a long appointment this morning, he is the best in Cornwall. I tried a few others, no one compares to him!!! I am originally from the West Island of Montreal, and he still is the tops!!!!!!!!!!!!
    —Sandy Goldfarb
  • I am a very nervous dental patient. I must say I am very happy with Dr Deneka and his team. They make you feel extremely welcome and comfortable. They even provide a local anesthetic (if you so desire) for your teeth cleaning. Highly recommend Cornwall Dental Arts.
