Display pages in blog format with limited content

Looking to display a page of pages, that appear like blog posts, with limited content. Am having trouble with limiting the content.

Here’s where the page is currently at: https://bechtelfoundation.org/about-us/board/

And the code I’m currently using:

<?php
	$mypages = get_pages( array( 'child_of' => $post->ID, 'sort_column' => 'post_date', 'sort_order' => 'desc' ) );

	foreach( $mypages as $page ) {
		$content = $page->post_content;
		if ( ! $content ) // Check for empty page
			continue;

	$content = apply_filters('the_content', $content);

	?>
    <div class="recent-post">
	<div class="post-content">
    	<div class="post-thumb"><?php echo get_the_post_thumbnail($page->ID); ?></div>
        <h2><a href="<?php echo get_page_link( $page->ID ); ?>"><?php echo $page->post_title; ?></a></h2>
		<div class="entry"><?php echo $content; ?></div>
    </div>
    </div>
	<?php
	}
?>
