Welcome to our practice! Since 1931, we have been privileged to provide family dentistry to patients in New Holland, PA and in the surrounding Lancaster County region. Our practiced has been blessed to have had 4 compassionate, caring owners who prioritize service to the community alongside high quality dentistry. In 1987 Dr. John Backof succeeded two previous generations of dentists, Drs. Stauffer and Poole, and continues to maintain the dental health of several of our patients who started with us in 1931! A true testament to preventative care! In January 2008 Dr. Melissa Della Croce joined Dr. Backof as a 4th generation dentist in a 4th generation dental practice. Dr. Andy Sieger joined Dr. Backof and Dr. Della Croce in 2015 and is the current owner of Sieger Family Dentistry!
"We value our patients as we do our friends",explains Dr. Backof. "The relationship we establish with our patients is something all of us value, as we have 3 and even 4 generations of families who have been coming to us for years. Our staff gives 110% effort everyday to insure our patients can maintain optimum dental health. Everything that keeps us alive goes into our mouth, and we are passionately committed to keeping your mouth healthy so you can eat the proper foods for your body's nourishment."
Dr. Sieger explains that, "The philosophy of our practice is simple: Treat patients exactly how you would like to be treated yourself. We place high importance on involving our patients in any decision-making involving their treatment. We strive to do what is in the patients' best interests, being sensitive to their particular concerns. We educate our patients as well, as we encourage them to be well-informed decision-makers."
We believe you will find our office to be upbeat and positive, as our staff truly enjoys what they do. In 2006 our entire staff went to Disney World in Orlando, and we were honored to receive recognition by a major dental consulting group as one of the best patient-centered dental practices in the United States.
We love new patients, and we would welcome the opportunity to become your family dentist. We are honored to work in the wonderful, caring community of New Holland and invite you to email or call Sieger Family Dentistry at any time to request an appointment or ask any questions. Thank you!
