It can by suprisingly simple if you have same amount of items on left and on right. Just create a list, put the logo in the middle and do text-align: center. See here: https://jsfiddle.net/DTcHh/26132/

The trouble starts when the left and right are even slightly uneven. I suggest creating two lists, each for half of the screen. They will be aligned towards the center and leave a space in the center for the logo.

html:

<div class="navbar navbar-default">
    <div class="logo-wrapper">
        <div class="logo"><img class="logo" src="http://www.hsdtaxlaw.com/wp-content/uploads/2016/05/logo_placeholder.png" alt=""></div>
    </div>
    <div class="half">      
        <ul class="left-navlist">
            <li>Home</li>
            <li>About</li>
        </ul>
    </div>
    <div class="half">      
        <ul class="right-navlist">
            <li>Contact</li>
            <li>Profile</li>
            <li>Maps</li>
        </ul>
    </div>
</div>

css:

.logo-wrapper {
    text-align: center;
    margin-bottom: -37px;
}

.logo {
    width: 100px;
    display: inline-block;
}

.navbar li {
    display: inline-block;
    padding: 0 10px 10px;
}

.half {
    width: 50%;
    display: block;
    float: left;
}

.right-navlist {
    padding-left: 60px;
}

.left-navlist {
    text-align: right;
    padding-right: 60px;
}

As for how to implement this with wordpress, I believe you will have to get rid of the navwalker plugin. Just create two menus in wordpress: left-primary and right-primary. Then just iterate them with wp_get_nav_menu_items('left-primary') and build the menu as I suggested. Here is the php code without the nav-walker:

<div class="navbar navbar-default">
    <div class="logo-wrapper">
        <div class="logo"><img class="logo" src="http://www.hsdtaxlaw.com/wp-content/uploads/2016/05/logo_placeholder.png" alt=""></div>
    </div>
    <div class="half">      
        <ul class="left-navlist">
            <?
                $menu = wp_get_nav_menu_items('left-primary');
                foreach ($menu as $menu_item) {
                    $title = $menu_item->title;
                    $link = $menu_item->url;
                    ?>
                        <li href="<?=$link?>"><?=$title?></li>
                    <?
                ?
            ?>
        </ul>
    </div>
    <div class="half">      
        <ul class="right-navlist">
            <?
                $menu = wp_get_nav_menu_items('right-primary');
                foreach ($menu as $menu_item) {
                    $title = $menu_item->title;
                    $link = $menu_item->url;
                    ?>
                        <li href="<?=$link?>"><?=$title?></li>
                    <?
                ?
            ?>
        </ul>
    </div>
</div>
