Chantal Causin, DDS
“I am committed to treating patients as if they were a member of my own family by providing comfortable, high-quality dental care. We have fashioned our office into a serene environment to offer patients a relaxing experience because we want them to feel comfortable and cared for in every way. Here, beauty and health are intertwined. Great smiles come not only from the work and expertise we provide but are also showcased through the health of the patient.” – Dr. Chantal Causin
Dr. Causin is originally from the West Bank; however, she lived in St. Bernard, Louisiana, with her family until the devastation caused by Hurricane Katrina in 2005. Afterward, she relocated to the north shore with her husband and their two sons. This is where she partnered her practice with Grand Family Dentistry, continuing to give the best dental care possible to the people in this community. She and the other doctors have come together with organizations such as Dentistry From The Heart and Dreams Come True Foundation, donating over 65,000 dollars of dental care to those less fortunate. Dr. Causin is dedicated to not only cosmetic transformations but also the overall health and well-being of every patient she sees.

William B. Grand, DDS
“Each member of my staff has been carefully hand-picked by myself, my partner and my associates. Their educational backgrounds range from registered nursing to college graduates. Each member has been individually trained to show dedication, commitment and compassion. They are the cream of the crop and form the core of my team. I believe that we were all given this life to make a legacy, to create something bigger than ourselves. At Grand Family Dentistry, I have led and trained all of my associates and staff to be compassionate, giving and exceptional people. I am proud of the dentistry we provide and the comfortable environment our patients have grown to love and expect. We are one of the few offices in the area that will work with our patients financially to make sure that they receive the treatment they need regardless of the cost. We strive to educate our patients first so they may understand their treatment and the ways they can improve their lives through prevention. Lastly, I am happy to announce we offer sedation dentistry in every office for those patients who have a hard time getting numb, those with high anxiety and those of you who desire complete mouth restoration but do not want to have multiple appointments. I am looking forward to welcoming you to my practice and giving you the ‘Grand’ treatment you deserve.” – Dr. William B. Grand
