They call me Shortcut Shari...Why? I believe we should all work smarter, not harder and I love keyboards shortcuts.

My philosophies for information architecture and SharePoint design are centered on solving business challenges with technology and ensuring usability and adoption for the organization.

As for my experience, I'm a Microsoft Certified Trainer, a Microsoft Certified Specialist Master, consultant, presenter, author and evangelist. When I'm not architecting SharePoint magic as a consultant, I'm in the classroom or creating online learning for LinkedIN Learning, ClipTraining.com and Pluralsight. Join me for my sessions, I promise they will not only be informative, but they will also be FUN!

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
