About Critical Signal Technologies

Founded in 2006 by security and medical monitoring expert Jeffery S. Prough, Critical Signal Technologies your Link to Life, is dedicated to helping our clients stay safe and healthy in their homes. As the nation's largest independent provider of Personal Emergency Response Systems and as one of the most innovative and respected providers of TeleHealth monitoring services, CST-LTL is committed to being your Link to Life

CST-LTL's products and services are all intended to help people overcome the challenges that can come from disabilities, chronic health conditions, infirmity, or simply from living alone. Whether we can help with just a reliable way of ensuring that assistance is available in an emergency, or a comprehensive health monitoring system managed in conjunction with your doctor, CST-LTL's cost-effective solutions help you protect your privacy and maintain your dignity in the comfort of your own home.

In 2009, CST-LTL acquired Link to Life, adding the team and resources of one of the nation's most respected monitoring and service companies. A pioneer in the field, Link to Life brought more than 30 years of premier monitoring and service experience to CST-LTL and its clients.

Our two world-class monitoring centers are staffed by trained and experienced professionals right here in the United States. These centers are staffed 24 hours a day, seven days a week, 365 days a year, with independently-certified technology backups that ensure that we're there when you need us. From our monitoring centers, we can summon assistance, or immediately put you in contact with family members, your doctor, your hospital, or any other caregiver who can help in a crisis when an ambulance ride isn't what's needed.

CST-LTL is the choice of state health agencies, health insurers, Agencies on Aging, physician groups, hospitals, and other health and safety experts who have done the research and selected CST-LTL's proven ability to provide quality, cost-effective services that improve their clients' lives.

However, most importantly, many of our own family members are CST-LTL clients… and we treat you just as we'd want them treated. That's our commitment, and that's why we hope you'll choose CST-LTL for your Link to Life.
