You're In Good Company

  • Excellent practice! Dr. Denis and all the staff were wonderful! I had a wonderful experience having 6 new crowns done. Dr. Denis was great at explaining and showing me the before and after. I am very happy with the results. I would definitely recommend my friends and family to her office!

  • Dr. DD and her team provide an excellent service and left me feeling like a star. I've never been to a dental office where I felt so much like a customer as well as a patient. They kept me well informed about each step in my treatment, concerned themselves with my comfort along the way, and never kept me waiting. This was the most satisfying dentistry experience I can recall.

  • I have been a patient of Dr. Denis for several years and both Dr. Denis and her staff are amazing. Always very professional and accommodating. Prior to seeing Dr. Denis, I always had teeth issues but she's helped me keep my natural teeth and help make them strong. I highly recommend!
    Cara D.
  • I have been going here for 8 years because I believe Dr. Denis is the best in the city. The time, care and interest she takes with each patient is so genuine and creates an over all great experience every visit. With the support of her truly amazing staff I instantly shout out to anyone that I over hear is looking for any sort of dental care to go and see Dr. Denis.
    Cory G.
  • Dr. Denis and her staff are professional and courteous. I trust them completely with my routine and emergency dental needs. They have responded to my needs promptly and were able to make me feel comfortable during a very complex procedure. My entire family goes to Dr. Denis. I recommend her as a dentist!
