About Your Dentist

Sarah Giacomini, DMD

“Life is short; smile while you still have teeth!”

My Mission

“My mission is to provide patients with a treatment environment where they feel comfortable and at home. I believe it is vital to work collaboratively with my patients, so I want them to be honest with me about their dental treatment goals and know that I am here to help them achieve those goals without judgment. I am dedicated to helping my patients maintain the smile they have always dreamed of having through oral health education, proper preventative care, and routine treatment. I truly believe that changing a person’s smile can change a person’s life. Every smile has a history, and with the right treatment and maintenance, every smile can have a future!”
