About Us
I have worn the uniform, worked the shift, and felt the adrenaline spike that doesn’t fade. I know the toll it takes on first responders, and that’s why Sigma’s cardiac screening isn’t optional- it’s essential.

About Us
Born from Frontline Experience, Built on Advanced Science
Sigma Tactical Wellness, a TeleMed2U company, was founded in 2016 by a team of physicians, PhD researchers, military veterans, and law enforcement officers. At the forefront are Ben Stone, PhD, a national champion for cardiac risk detection, and Jon Sheinberg, MD, FACC, a board-certified cardiologist and sworn law enforcement officer. Together, they launched SIGMA with one mission: to reduce the number one killer of men and women in uniform, heart attack.
By combining advanced cardiovascular screening with personalized care, SIGMA delivers the most effective cardiac screening and treatment program in the public safety sector. We detect risk early, mitigate that risk, and protect those who protect us. Our programs bridge the critical gap between conventional healthcare and the unique physiological demands, high-stress environments, and cultural realities of tactical professions. We don’t just assess health; we build resilient warriors.
With 25,000+ emergency responders served nationwide, Sigma Tactical Wellness has become a national leader in detecting cardiovascular risks that standard healthcare models fail to identify.
We’re not just protecting hearts. We’re honoring the people behind them.

Our Approach
Acknowledging that traditional medical screenings frequently overlook early indicators of heart disease, Sigma Tactical Wellness has developed comprehensive programs tailored to the rigorous demands of first responders. The methodologies include:
Advanced Cardiometabolic Screening:
Utilizes vascular imaging, inflammatory biomarker analysis, and cardiopulmonary exercise testing to detect early stages of cardiovascular disease.

Accessible Programs:
HeartStart+ is a convenient and powerful health screening program designed for first responders. It includes a blood test that looks for hidden signs of heart disease, along with a review of your results by a licensed medical professional. Within business 10 days, you’ll also have a one-on-one telehealth visit with a cardiac provider who explains your risks and starts a plan that could include medication, supplements, or lifestyle changes to help you stay healthy and safe on the job.
On-Site+ brings full-spectrum heart and metabolic health testing directly to your workplace. It includes an ultrasound to check your arteries, a fitness-based stress test, and bloodwork to detect early signs of heart or metabolic issues. You’ll also meet with an exercise specialist and a medical provider—first through an online review, and then in a live telehealth visit—to create a custom plan that helps improve your health and reduce the risk of future problems.
SIGMA 360 is the most advanced and complete heart health program we offer. It includes all the same testing as HeartStart+ and On-Site+—like bloodwork, imaging, and stress testing—but adds 90-day follow-up testing and unlimited access to a team of specialists. You’ll work closely with medical providers, a cardiologist, endocrinologist, and a nutritionist to create a long-term, personalized plan that helps manage everything from weight to blood pressure to heart health, ensuring you’re supported every step of the way.
These programs have been instrumental in identifying early-onset heart disease in a significant number of first responders, many of whom showed no prior symptoms. By addressing these risks proactively, Sigma Tactical Wellness aims to improve on-duty performance and ensure a healthier retirement for those who serve our communities.
