A labor of love since 1985
In 1985, Patti and Lisa passed the California geology registration exam, turned their notes and tables into handouts, and started a study group in San Francisco. When ASBOG® was formed, they expanded beyond California to prep geologists all over the country. On top of being mothers and working geologists, they spent weekends developing and refining their review courses, study manuals, and practice tests. More than 40 years later, REG REVIEW is still taught by working geologists who hold full-time jobs in environmental consulting, state agencies, and the USGS, with specialties from hydrogeology to engineering geology to structural mapping. Lisa and Patti used to fly all over the country to teach. Now we come to you by live webinar, and we’re available to answer questions or work through that contour problem more slowly. After every exam we read your feedback and update the course to make sure it has the latest information possible. We love the chance to nerd out with you on our weekends, and hearing that you passed is the best part of the job.
