Edward Roske - Director  @ERoske

My name is Edward Roske and I love to learn things and pass them on. This is why I've helped write 15 books on EPM and Analytics, it's why I've made over 50 YouTube videos, it's why I've delivered over 100 webcasts, and it's why I've traveled to 7 continents to educate students in over 60 countries. And in 1997, my love of education led me to found interRel Consulting, so that we could leave the world a smarter place than we found it. I have helped bring interRel together with *11* other companies to make up Argano where I'm now Chief Performance Officer. I'm an Oracle ACE Pro and graduated at the top of my class from SMU with a Masters of Data Science in Business Analytics. My goal is to make sure that you always leave any session with me knowing three more things than when you arrived. Let's get started.
