Ok, so I'm really not sure the right way to do this...
I more or less have wording for my invites down (ordering tomorrow *fingers crossed*), but I don't know how to do titles. My dad and FFIL are both PhDs, so Dr....but putting Dr. on the invite kind of implies medical.
According to my dad, first names, Dr. or Mr. are all technically correct (and he doesn't care...tho I have a feeling FFIL will care as he always introduces himself as 'Dr.') So yes, anybody know what's appropriate on formal invites regarding those who are 'piled higher and deeper'?
