<p>At my hospital, we have PhDs ad MDs working side by side and they all get called “Doctor”.</p>
<p>When I was in grad school I had a professor with a Phd who snarkily said that MDs shouldn’t be called ‘Doctor’ because they were really just body mechanics. :)</p>
<p>IMO, if someone earns the degree, they have the right to use the title.</p>
