Donna Stepanian

With over two decades of experience in Geographic Information Systems (GIS), particularly in the energy and land management sectors, I bring a unique combination of technical expertise, cross-functional collaboration, and strategic insight that would greatly benefit your team.

Throughout my career, I have successfully led the implementation and upgrade of enterprise GIS systems, including Esri Enterprise GIS Server and Quorum Land GIS solutions.

At Sabinal

Energy, I manage all internal and vendor spatial datasets and provide GIS support across departments such as Land, Regulatory, Reservoir, and HSE. My technical proficiencies include ArcGIS Pro, ModelBuilder, FME, and Power BI, which I use to automate workflows, maintain data integrity, and deliver high-impact visualizations and reports.

Beyond my technical capabilities, I take pride in mentoring team members, establishing best practices, and ensuring that GIS solutions align with operational goals. I also hold a Master of Science in Geographic Information Systems from Sam Houston State University and have consistently pursued continued learning to stay at the forefront of GIS innovations.
