Yes, of course you can. In fact, one of the reasons we like to use WordPress is that you can easily update the content by yourself.
In fact, all websites come with a 2-hour training session to teach you about how to update everything by yourself.
We don’t just then stop after 2 hours and leave you to it. Olive & Lake has very cost effective maintenance plans and we’re always available to answer any questions you have. If you need more training, we can arrange that too.
