No hassle promise

At Tierzero we focus on one goal – delivering no hassle voice and data to Southern California businesses. We insist on making sure every single client is not just satisfied, but happy. Your expectations are our responsibility.

Tierzero has grown and prospered mostly by word of mouth. Our customers don’t recommend us for empty slogans or mission statements. They do so because they know the power of having a vendor that’s got their back.

We welcome you to experience our no hassle promise.

John Carter

Founder and CEO

I’m passionate about exceeding customer expectations for internet and phone service.

John Carter

FOUNDER AND CEO

I always try to put myself in the shoes of our customers when solving their problems.

Hans Offer

CUSTOMER CARE SPECIALIST

We believe our customers shouldn’t have to worry about their service. We know our customers count on us and we’re accountable for that.

Mike Gach

VP OF SALES

Tierzero began over 20 years ago as an effort to disrupt the telecommunications industry, so we understand the frustration when it comes to dealing with the big phone companies. We believe it’s our job to make the lives of business owners and IT managers less complicated and deliver an elegant solution that works with the least amount of hassle.
