John McGehee

Vice President of Administration at Bud’s Ambulance Service | Daley’s Ambulance Service

The sound quality blows away any radio equipment we have. You can’t get that nice clear digital audio out of a radio unless you buy a very expensive radio system and put repeater towers in place to boost the signal.

Jimmy Brissie

Director of the Henderson County Emergency Services

During a dynamic event we can create a conversation with different users on the fly by building an ad hoc channel with multiple users.

Lor Dykes

Operations Lead at Crowdsource Rescue

It’s different when you hear the urgency in someone’s voice. It’s instant. You don’t have to call. With Zello, you just push the button.

Sim Shain

Advanced Life Support Coordinator of Hatzolah of Central NJ and the Operations Coordinator for Hatzolah Statewide.

Zello works perfectly for us because we can expand and broaden our network anywhere. Yesterday I was flying to Houston and I could communicate with our team from 35,000 feet, which is something I could never do otherwise.

Ken Kelley

Owner, ProMed Ambulance

There are a lot of radio channels to keep up with, but with Zello, I can manage all my operations from one central dashboard.

Holger Sommer

Communications Manager, @fire

The big advantage of Zello is that it requires only a basic data connection and works already with 2G/GPRS. Often we couldn’t call someone with the cell phone, but Zello worked.

Your safety matters too

One touch and hands-free accessories keep you focused on what’s in front of you without worrying about what’s behind you—and when you need it, emergency alerts are just a button push away.

Works on any network

You can’t choose where emergencies take you. Zello works across any network on any device anywhere in the world. When urgent situations make networks unstable, Zello intelligently utilizes what little bandwidth there is to give you one less thing to worry about.

Critical productivity

When there are no second chances, Zello is the first choice.
