(3) day Technician Seminar

This photo was taken while my Dad, Thomas Lee Wilkerson was attening a (3) day X-Ray Technician Seminar.

Does anyone recognize the man standing beside My Dad? During their breaks from class My Dad remembers a conversation between them of this man (Mr.McGothalin?), speaking of recenting getting married to a Lady from Ft. Smith, Arkansas, and her last name was WOOD/WOODS. Does any of this sound familar? I would like to make a connection with this couple and My Dad.
