Jeanette “Jet” Stiffler
Founder & Owner, NH3 Training Center
Entrepreneur | PSM/RMP Industry Leader | Trainer | Speaker | Business Builder
Jeanette “Jet” Stiffler is an entrepreneur, business leader, trainer, and nationally recognized process safety professional with more than 30 years of experience in OSHA Process Safety Management (PSM), EPA Risk Management Program (RMP) compliance, and the industrial ammonia refrigeration industry.
Jet began her career in the petrochemical industry in 1995 and soon became involved in building what would become a decades-long career in regulatory compliance, training, and business development. She co-founded Process Compliance, Inc., helping grow the company into an established compliance organization serving the industrial refrigeration industry.
In 2015, Jet founded JS Compliance, LLC and built the company from the ground up. Under her leadership, JS Compliance grew to approximately 30 employees and served more than 300 facilities across the United States. In November 2024, she successfully sold JS Compliance to Kelvin Group, marking another significant milestone in her career as an entrepreneur and business builder.
Throughout her career, Jet has worked directly with facility owners, executives, managers, operators, technicians, and PSM professionals to develop and strengthen regulatory compliance programs. Her experience includes PSM/RMP compliance audits, Process Hazard Analyses, OSHA and EPA inspection preparation, program development, management training, and workforce education. She has also trained regulatory personnel and presented technical and educational programs within the industrial refrigeration industry.
Building the Next Generation
In 2024, Jet founded NH3 Training Center, bringing together more than three decades of industry experience with a new mission: to develop knowledgeable, confident professionals who understand not only what the regulations require, but how those requirements apply in real-world facilities.
NH3 Training Center provides education for industrial refrigeration operators, technicians, PSM professionals, supervisors, managers, executives, and other personnel responsible for the safe operation and regulatory compliance of ammonia refrigeration systems.
The company’s expanding curriculum includes ammonia refrigeration operator education, PSM/RMP compliance, Process Hazard Analysis, mechanical integrity, IIAR standards, compliance auditing, standard operating procedures, management of change, incident investigation, emergency response, RAGAGEP, and advanced professional development.
Jet is also expanding NH3 Training Center beyond the traditional classroom through national training programs, hands-on mechanical education, professional development programs, and e-learning designed to make high-quality industrial refrigeration and process safety education accessible to facilities throughout the United States.
Experience With a Purpose
After more than 30 years in the industry, Jet’s focus is no longer simply on building another successful company. It is on transferring decades of knowledge to the next generation.
She believes effective training should go beyond memorizing regulations or passing an examination. Operators should understand their systems. PSM professionals should understand why the regulations exist. Managers should understand their responsibilities. And companies should be able to turn regulatory requirements into practical programs that protect their employees, their facilities, and their communities.
That philosophy is at the heart of NH3 Training Center.
For Jet, this next chapter represents the culmination of a career spent building businesses, developing people, solving compliance challenges, and helping companies operate more safely.
