Karey Tomlin

Owner / Founder

Karey Tomlin is the Founder and Chief Operating Officer of Life Saving Certifiers, a mission shaped by both professional service and personal loss. As a career Firefighter/Paramedic, Karey has dedicated her life to helping others in their most critical moments, but her deepest motivation began when her grandfather passed away from a heart attack. That loss made the importance of immediate action, proper training, and access to life-saving resources painfully clear. It transformed Karey’s passion for emergency response into a calling for education, empowering everyday people with the skills and confidence to act before it’s too late. This calling led to the creation of Life Saving Certifiers, an organization committed to delivering high-quality life-saving classes, AED services, and comprehensive maintenance programs. Every instructor is a Firefighter or Nurse, bringing real-world experience into every class and ensuring training is practical, engaging, and impactful. The Life Saving Certifiers team has trained a wide range of organizations, helping build safer workplaces and stronger communities. Karey holds certifications through the American Heart Association, Health and Safety Institute, and the Maryland Fire and Rescue Institute, and earned a Bachelor’s degree in Criminal Justice from the University of Baltimore. Karey resides in Frederick, Maryland, with her wife, Amber, and their daughters, Harper and Savannah. Her work is guided by a simple belief: education saves lives, and preparedness turns loss into purpose.
