Lindsay Shelton

Lindsay is an MVP (Business Applications, M365 Copilot), MCT alumni, Digital Workplace Advisor, international speaker, and user group organizer who is committed to keeping business productive by embracing technology as a tool to problem-solve.

Her aim is to empower makers to create and thrive while doing so in a secure, governed way.

Lindsay spent the last decade teaching English Language Arts and was selected to receive training to become a technology and pre-engineering teacher based on her aptitude for learning and adapting new technologies with her own students and colleagues.

She holds a BS in Secondary English Education from the University of Kansas and an MS in Curriculum and Instruction from Emporia State University.

In her spare time, Lindsay enjoys spending time with her two cats Charlie and Trixie, and marathoning a wide variety of television shows.

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.
