Thirty years ago, Geoscience hired a graduate intern from USC. This intern, Johnson Yeh, would later receive his Ph.D. in Sedimentology and begin working full-time for Geoscience.
In time, he becomes a Professional Geologist and Certified Hydrogeologist and rose through the ranks to become our chief groundwater modeler.
Over the past three decades, Johnson has been critical to our company’s success, and on his 30th anniversary with us, we want to thank him for all that has done and continues to do for us.
Thank you, Johnson, and congratulations on 30 years!
