How do I change words in the top of Front Page which is not part of front page
I am very new to Wordpress, am having to figure out how to make changes to my website. I can change the front page and the rest of the pages, but the heading that is above my front page I dont know how to change it. So if you go on www.angelstouchreiki.com at the very top it says Angels Touch Reiki and underneath it says serving All of Arizona and California and I need to change it because I serve the whole world not just those 2 states. I dont know how to do that, please help!
