i have this html mark-up to sort some data

<div class="row">
<div class="col-xs-2">
  <img src="images/member-schools/ms1.jpg" class="img-responsive">
</div>
<div class="col-xs-4">
  <h4>American International School - East</h4>
</div>
<div class="col-xs-2">
  <img src="images/member-schools/ms2.jpg" class="img-responsive">
</div>
<div class="col-xs-4">
  <h4>Dover American International School</h4>
</div>

and i am pulling out the data from repeatable group metabox i use from CMB2

this is the code for the registered metabox

function schools() {

// Start with an underscore to hide fields from custom fields list
$prefix = 'schools_';

/**
 * Repeatable Field Groups
 */
$schools= new_cmb2_box( array(
    'id'           => $prefix . 'metabox',
    'title'        => __( 'schools', 'cmb2' ),
    'object_types' => array( 'page', ),
    'show_on'      => array( 'key' => 'id', 'value' => 6 ),
    'closed'     => true,
) );

$group_field_id = $schools->add_field( array(
    'id'          => $prefix . 'field',
    'type'        => 'group',
    'options'     => array(
        'group_title'   => __( 'Slide {#}', 'cmb2' ), // {#} gets replaced by row number
        'add_button'    => __( 'Add Another Slide', 'cmb2' ),
        'remove_button' => __( 'Remove Slide', 'cmb2' ),
        'sortable'      => true, // beta
    ),
) );


$schools->add_group_field( $group_field_id, array(
    'name' => __( 'Photo', 'cmb2' ),
    'id'   => 'photo',
    'type' => 'file',
) );

$schools->add_group_field( $group_field_id, array(
    'name' => __( 'Name', 'cmb2' ),
    'id'   => 'name',
    'type' => 'text',
) );}

i pull the data out through this code

$schools = get_post_meta( get_the_ID(), 'schools_field', true );

where $schools is an array that contain an image and title for each entry which i can loop through to pull out the values.
my question is how i can add <div class="row"> every two items from that array , because i need a row for each two entries

EDIT: var_dump result

array(3) {
    [0] => array(3) {
        ["photo_id"]    => string(2) "89"
        ["photo"]       => string(56) "http://localhost/NCSR/wp-content/uploads/2015/06/ms3.jpg"
        ["name"]        => string(8) "School 1" 
    }
    [1] => array(3) {
        ["photo_id"]    => string(2) "88"
        ["photo"]       => string(56) "http://localhost/NCSR/wp-content/uploads/2015/06/ms2.jpg"
        ["name"]        => string(8) "school 2"
    }
    [2] => array(3) {
        ["photo_id"]    => string(2) "87"
        ["photo"]       => string(56) "http://localhost/NCSR/wp-content/uploads/2015/06/ms1.jpg"
        ["name"]        => string(8) "school 3"
    } 
}
