Send workflow emails to the managers of multiple users added to “person or group” column/field

I have a simple SharePoint list and I want to send multiple emails when a new item is added:

  1. Email to the creator (straight-forward)
  2. Emails to each of the potentially multiple users added to “person or group” column/field (straight-forward)
  3. Emails to the managers of the potentially multiple users added to “person or group” column/field (is this possible)

Does anybody know how I can achieve automating emails to the managers? Is this something that can be achieved using a 2010 or 2013 workflow in SharePoint Designer? Is there a better way to approach this?
