Dr. Thomson serves as an independent contractor providing physician oversight and supervision during testing — he is not an employee of First Responder Performance.
Tiffany grew up on a small working cattle farm in Southeast Virginia, where she developed a strong work ethic and a passion for helping others. After completing her undergraduate degree in Biochemistry and Religious Studies at the University of Virginia, she discovered her true calling in exercise physiology while earning her Master's in the same field at UVA. During her time in college, Tiffany volunteered at a local rural rescue squad, earning her Cardiac Technician certification and serving as the squad's lieutenant.
Her first role after graduation was as an exercise physiologist for Phase III–IV and faculty/staff wellness at Towson University in Maryland. She later moved to Colorado, where she grew a novel heart disease prevention program and embraced the Colorado lifestyle. Over more than 25 years, her work has focused on improving first responder health — spanning cardiovascular disease risk assessment and lifestyle modification, cancer prevention, carcinogen exposure, temperature regulation, cooling mechanisms, noise exposure, and performance, particularly within the firefighting community.
Outside of work, Tiffany has two sons — one a senior in college and the other a sophomore in college. She loves sports and treasures her small collection of orchids.
Dr. Thomson has been an EMS and Emergency Physician for over 30 years. After receiving his M.S. from the Human Performance Lab at Ball State, he worked in cardiac rehabilitation before attending medical school. He became interested in EMS during his residency at the University of Pittsburgh and has since served as medical director for several air ambulance and EMS services, as well as an emergency physician and faculty member at multiple university and community hospitals.
His clinical background in emergency and prehospital medicine — combined with his foundation in human performance — makes him uniquely equipped to provide physician oversight for comprehensive first responder evaluations. Dr. Thomson provides real-time physician supervision during maximal treadmill stress testing and reviews results alongside the clinical team.
Outside of work, Dr. Thomson enjoys flying, photography, and spending time with his wife, their dog, and their grown children.
