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.

When I’m not working with my Tetra family, I spend my time reading a good book, drinking good coffee, eating good food, hiking my favorite trails, lifting weights, and taking care of my family. I enjoy my home life as well as traveling and exploring new places. At Tetra you will find me on the other side of the phone and marketing, y si hablas espanol yo soy tu.

Nate Garcia

Water Technician

Proud native of San Antonio, Texas. Hard work, Spurs and respect are a few values I keep close to heart. Being a husband and a first time father of a baby boy has been one of the most amazing experiences for me recently. Working for an employer that understands the importance of family and work life balance is not very common, but I’m proud to be a part of one that does at Tetra Water. From every install to every service call, I do to the best of my ability and with the most diligence. I’m thankful for the work I get to do and the people who allow me to be a part of their home and their day.
