A Few Words About Us

Less Stress Instructional Services is an independent training agency formed by John Mateus and Mary Rongo in 1994 for the purpose of providing EMT's with an easy way to renew their CPR qualification. It quickly became obvious that there was a great need for emergency care and other training both in the community at large and within the industry of pre-hospital care. The agency grew quickly into a still small but ever-changing entity serving several hospitals, long-term care facilities, schools and corporations. A variety of educational projects are available ranging from emergency care to OSHA compliance to general health. Computer-based training has been a very successful outlet for us and we plan on adding more programs to our store and seeking additional distribution channels.
The agency now employs seven full-time staff members (including the two founders) and a list of over two dozen per-diem instructors of varied expertise.
