Normally when listing a group of people you would simply separate each with a comma.

> 
> Please send the memo to Jason, Sarah, and Courtney. 
> 
> 
> 

However if you want to include the title of each person

> 
> Jason, Chief Information Officer  
> 
>  Sarah, President  
> 
>  Courtney, Investor
> 
> 
> 

It would end up looking like a list 6 people (or 5).

> 
> Please send the memo to Jason, Chief Information Officer, Sarah, President, and Courtney, an investor.
> 
> 
> 

Is there a proper way to do this?
