php - Div not wrapping around all items in a loop

I got 2 sections on a page. You can see it here: http://www.equitasmg.com/who-we-are-2/

Both sections have a<div> wrapped around them, but the first section "Our Leadership" seems to not like the<div>. The<div> wraps around the first item in the section but does not wrap around all the items.

Here is the PHP for both sections.

First section

 <center><h2>Our Leadership</h2></center>
 <center><div>
 <?php
 $people= get_field('people');
 $a=0;
 foreach ($people as $r) {
$a++;
?>
     <div >
      <img src="<?php echo $r['image']['sizes']['team'];?>" >
      <h3>
        <?php echo $r['name'];?>
      </h3>
      <div >
        <h4><?php echo $r['position'];?></h4>
      </div>
      <?php echo $r['intro_text'];?>
      <?php if ($r[ 'learn_more_text']) { ?>
      <a href="#" data-reveal-id="<?php echo sanitize_title($r['name'] );?>">Learn More</a>
      <?php } ?>
 <?php if ($r[ 'learn_more_text']) { ?>
 <div id="<?php echo sanitize_title($r['name'] );?>" data-reveal aria-labelledby="modalTitle" aria-hidden="true" role="dialog">

<h3><?php echo $r['name'];?></h3>
<div >
  <?php echo $r['position'];?>
</div>
<div >    
<?php echo $r['learn_more_text'];?>
</div>
<a aria-label="Close">&#215;</a>
 </div>
    </div>
 <?php } ?>
 </div>
 <?php } ?>
 </div></center>
 <div ></div>

Second section

 <center><h2>Our Team</h2></center>
 <center><div>
 <?php
 $people2= get_field('people_bottomsection');
 $a=0;
 foreach ($people2 as $r) {
$a++;
?>
     <div >
      <img src="<?php echo $r['image']['sizes']['team'];?>" >
      <h3>
        <?php echo $r['name'];?>
      </h3>
      <div >
        <h4><?php echo $r['position'];?></h4>
      </div>
      <?php echo $r['intro_text'];?>
      <?php if ($r[ 'learn_more_text']) { ?>
      <a href="#" data-reveal-id="<?php echo sanitize_title($r['name'] );?>">Learn More</a>
      <?php } ?>
 <?php if ($r[ 'learn_more_text']) { ?>
 <div id="<?php echo sanitize_title($r['name'] );?>" data-reveal aria-labelledby="modalTitle" aria-hidden="true" role="dialog">

<h3><?php echo $r['name'];?></h3>
<div >
  <?php echo $r['position'];?>
</div>
<div >    
<?php echo $r['learn_more_text'];?>
</div>
<a aria-label="Close">&#215;</a>
 </div>
    </div>
 <?php } ?>
 </div>
 <?php } ?>
 </div></center>
 <div ></div>
