Gather the relevant information
Make sure you have all the information your patients and vendors need to know, including the new address, the new phone number, and all other contact information, such as email address, fax numbers and website URLs.
Determine your mailing list
Create a mail merge list of all your patients and vendors. Use this as an opportunity to strike people off your contact list if they haven't been in touch with your medical business in many years. Decide whether you want to create separate relocation letters for patients and vendors.
Write your relocation letter
Include all your contact information in the relocation letter, even if some of it isn't changing. Briefly explain the reason for the move, and don't forget to include the date of the move.
