New neighbors probably need a new dentist
When people move to a new neighborhood, one of the most common things they will need to do in the first couple of weeks or months is to find a new dentist to serve their family. So, if you represent a dentist office and are accepting new patients, this could be a great opportunity to grow your practice.
The US Postal Service, for one, has a service that they provide to families who put in a change of address request. People can opt-in for sales, promotions, and offers which normally include moving services but could also include local services such as dentistry. Creative and resourceful dentists can also subscribe to lists to discover who recently purchased a property in specific neighborhoods.
If you are accepting new patients, think about how you can welcome new families to the neighborhood.
