List out all the corporate events you have here. Include in some nice photos to let people know what is happening in your company. The key about this section is that it can constantly evolve and must be kept current and up to date. This makes your website refreshing and there are reasons for your viewers to click and check out what is new in your company on a regular basis.
If Events are a Main Stream or Main Highlights for your business, then you can opt to put Events as a stand alone Main Menu Page (instead of a sub page under About Us)
This usually applies for company that organizes a lot of events for their staff, customers etc. Or for an Event or Training Company that organizes a lot of Seminars, Workshops, Conferences and Events etc.
