Text next to brand

How do I get the Bootstrap Brand and any accompanying text to be treated together as the brand?

I have tried this:

<nav class="navbar navbar-default">
    <div class="navbar-header">
        <div class="navbar-brand">
            <a href="..." ><img class="img-responsive" src="/brand.png")?>"></a>
            <h3>Ultimate Trade Sizer</h3>
        </div>
    </div>
</nav>

However, I can't get them to be aligned (i.e. side by side). It produces the below effect:

Please note that I am using Bootstrap 3.
