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

Dr. Grand has dedicated more than 13 years to providing families in our community with quality dental care for a lifetime of healthy, beautiful smiles.
