Many of us create our own Facebook pages for our practices. However, there are instances where Facebook will have already created a Facebook page for your office in the hopes that you will claim the page and now be active on Facebook. In these cases it's possible to merge the "unofficial" page that Facebook has created for you with the "official" page that you have created and verified for your practice. Note these steps will only work if you already have a verified Facebook page for your office.
If you are in this situation you can easily merge the two pages using the following instructions.
1. Navigate to the unofficial page (the one you would like to delete -- and therefore merge into the "good" page). Click the three dots at the top right section of the bar in the middle of the page. Click "Is this your business?"
2. Select option 1, to "Merge....into a Verified Page you manage".
3. You should then be able to complete the merging process.
