I am using appointment+ with a single service provider

I am using appointment+ with a single service provider and just above the calendar the text reads
"Our Schedule for......"
As I am using a single service provider I would like to change the text so it reads
"My Schedule for....."
Can you let me know in which file I can find the text so I can change it. I have a looked in the admin side of the plugin but cannot find that option.
Thanks
Allan
