I'm just trying to get a hold of an actor who I went to high school with 50 years ago. How do I do that?[

I'm trying to get a hold of an actor named John Henry Whitaker. We were great friends and we graduated high school almost 50 years ago. I would just like to send him a hello as I have not seen him in about 38 years.

Sincerely 

John Marfiak
