Sarah Garcia

Class 3 Technician & Office Assistant

Hi, I’m Sarah a class 3 technician who started out in the field with a shovel in one hand and a test kit in the other. Although the arrival of my children has meant passing down the title of “Fastest Shovel in the West”, my thirst for knowledge and passion for learning everything about the fascinating world of water has never faded. My goals are to keep growing professionally, and to get dinner on the table on time. When I’m not in the office, you can usually find me baking something up in the kitchen or getting completely lost in a good book.
