I am having a graduation party for my son and niece.  They attend different schools with different school colors.  They are both going to college (also different school colors).  I need some ideas for a cake incorporating all of this along with their fields of study (Paramedic/EMT/Firefighting and Dental Assistant/Dentist/Orthodontist).  I don't want to do two cakes.  I can use all the help I can get.  Thanks!

Perhaps a tiered cake with a tier for each school?

ie. Person A's red/white tier with medical-themed decorations on top of Person B's blue/yellow tier with dental decorations

I'm sure you could do something else, but that's as simple as I can think of.

AWe'd do a two sided cake that way each kid could take a pic with their side and together!

AI think a 2 sided cake will be the best option

Since they're both going into medical related fields, maybe put medical caduceus right in the middle of the cake to divide it in two, and then decorate each half accordingly?

Or do the firefighter's maltese cross on one side, and the dental caduceus on the other side?
