Willard Gustafson -I'm a scientist at heart; and a bit of a tinkerer. I love using GIS to solve spatial problems. After earning my Master’s Degree in Geography in 2002, I began a career as a satellite imagery analyst; creating vegetation maps and performing other spatial analyses for wildlife biology studies at The University of Montana's Cooperative Wildlife Research Unit. In 2008 I continued my career, after starting a family and moving cross-country, with Meshek & Associates PLC where I now specialize in 3D data analysis, server applications, and mobile data collection technologies.  I have been an active member of Oklahoma SCAUG since 2008, and have been a member of the SCAUG Executive board as the Oklahoma Representative since 2014. I aspire to bridge the gap between the GIS “Geeks" and “End-Users” by presenting the technology in a way that everyone can relate to and understand. I believe Geography is the hub of many disciplines, and if applied correctly, can be the means by which we connect and make sense of them all. GIS is the grease on the axles of business!

Talia Gammill - Talia been involved with OK SCAUG since 2010, and has served on the Steering Committee since 2012. Talia has been with Cotton Electric Cooperative, located in Walters, OK as GIS Specialist for the last 18 years.  While working in this field, she provides all necessary GIS data to help aid the Coop in planning, design, and analysis to improve and maintain the electric distribution system.

Greg Hakman  - Maps have always been part of Greg Hakman’s life.  Growing up with a father in the Air Force, he loved looking at maps to see where he was moving to next or where he was heading on the next family vacation.  Little did he know, he would make a career out of making and reading maps.  Greg brings 17 years of GIS experience to Midwest City as the GIS Coordinator.  Greg holds a BS and MS from Oklahoma State University in Geography.  His GIS background is diverse with experience working in various industries ranging from municipal government, oil and gas, and as a private consultant.  Greg is an avid aviation buff and holds his private pilot’s license, as well as an FAA Part 107 drone pilot’s certification.  Greg will be working with OKSCAUG as the new Outreach Coordinator.  Greg has been married to his wife Melissa for 16 years and they enjoy traveling, cooking, BBQ/smoking, and cheering on the OKC Thunder and OSU Cowboys.

Madeline Dillner - "Everything is related to everything else. But near things are more related than distant things.” When one of my professors told us Tobler’s first law of geography in college, I knew I’d found the right profession. I live to find patterns and show them to others. When I was 12 I read the book Life by the Numbers that talked about fractals in nature, and it was intoxicating to me. It taught me that patterns can be observed, noted, and used to make predictions in the natural world. That is, patterns bring order to what seems like chaos. So, this analysis of patterns became a constant, underlying hum in my thoughts throughout my life. Naturally, this led me to geography in college—the study of patterns and arrangements of places and people. Before graduation, I had begun working for the Oklahoma Corporation Commission as a GIS intern, and today I am the Project Coordinator for the OCC Brownfield Program, and I manage the Oklahoma Historical Aerial Digitization Project. I serve on the OKSCAUG Steering Committee as the Co-Conference Coordinator.
