How Tech OG Started

After taking time off to raise her young family, Sarah Hebeler faced the challenge of reentering the workforce without compromising time at home. She explored various paths, from substitute teaching to launching a furniture upcycling business. Throw in a global pandemic for added complication, and any progress came to a standstill—until a former colleague encouraged her to revisit her extensive experience in operations geology and drilling.

She returned to the industry in an entry-level role building wellbore diagrams and quickly reestablished her technical footing. As her skills grew, so did the opportunity. What began as a solo consulting effort evolved into Tech OG—a business built on experience, resilience, and Sarah’s vision to create meaningful work for others.
