Why Choose Sierra Tel?

Local Service and Support:
We’re located in Oakhurst and Mariposa. Our employees work, live, and play in the same communities as our customers. When you call our office, you’ll immediately reach a friendly local employee to assist you. Should there be an issue with your equipment, the same local technicians who installed it will come out to fix the problem.

An Exceptional Commitment to Customers:
At Sierra Tel, customer service is not a department; it is our company-wide philosophy. Every employee is dedicated to providing friendly customer service that goes above and beyond.

Respect and Professionalism:
Some security providers show up unannounced with pushy sales pitches. Not Sierra Tel. We’ll be happy to come to your home or business to discuss your security needs, but only if you request a consultation.
