Yes! You have two options if you already have a domain name.
The easy option:
Simply change the “nameserver” settings at your current domain name registrar to our nameserver settings. We give you the name of the new nameservers once you sign up for your hosting.
The other option:
We can actually transfer the domain name to us. This often is a little more complicated, and requires the domain name be unlocked, and that you provide an auth code to us. This can be done after you sign up for your web hosting by contacting our web hosting department. Contact us if you would like to transfer the domain name to us.
