What you can expect from a
Learning Edge class?

Tons of Content

Bring your pen and paper (or open a doc to type in) because you'll need it!  A little like drinking from a fire hose, but we promise not to drown you.  Handouts to follow along during class and copies of the presentation are always made available to attendees to refer back to after class.

Interesting not Boring

Every class is fast paced with a mixture of text and lots of pictures and graphics, all designed to make the valuable information you're learning interesting, digestible, and even entertaining.  Attendees remain engaged with polls, hand raising, and time allowed for Q&A.


Most of what you learn will be something that you can use or apply right away, not only in your professional life, but also your personal life.  You won't think about the buildings where you work, live, shop or dine in the same way ever again.  That's a promise!
