Have you searched the page template(s) for this text or considered it may be added from a plugin or theme? Can you share a link to this and note the exact text? The source code of the page may help reveal the issue.

At the bottom in italics where it starts with “Want more leadership…” majority of posts have that.
Have you checked in each post if there are any custom fields? Might be there…or, if not:
I would look at the single.php file in your theme.
For reference I am making this decision based solely on the output of the body classes:
<body class="single single-post postid-8894 single-format-standard body_width">
Note: single.php may make use of a content template part…it may be within that file. If so, you may see something like this in single.php (example from twentyeleven theme):
<?php get_template_part( 'content-single', get_post_format() ); ?>
So the file to look for in that case would be content-single.php
If not that, here is what I would do to hasten this:
Download your current theme folder, all files in it. Use you computer to perform a search of the downloaded folder/files making sure to search within the files for this text.
Couldn’t find the text in either of those, and I searched file contents as well.
