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:

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.
