About The training

Providing Critical Incident Education

Our primary purpose is to provide education regarding critical incident stress (CIS) and secondary goal is to minimize the harmful effects of job stress, particularly in crisis or emergency situations. 

Using the critical incident stress management (CISM) process, our team provides personnel with beginning tools or psychological first aid to alleviate potential stress related reactions before they become symptoms. 

Our team has a certified instructor accredited through the ICISF (International Critical Incident Stress Foundation) who provides leadership, education, training, consultation, and support services to emergency response professions, and other related organizations in delivering quality Critical Incident Stress Management (CISM) materials.
