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
Dr. Jon Sheinberg is not your typical cardiologist. He is a board-certified cardiologist and a sworn law enforcement officer~ one of the rare few in the nation serving simultaneously in both roles. This unique dual perspective has shaped his life’s mission: protecting those who protect us.
After decades on the front lines of both medicine and public safety, Dr. Sheinberg saw what others often missed, an epidemic of silent cardiovascular disease threatening the lives of first responders. Too many were being lost to heart attacks that could have been prevented. He knew the system needed to change.
Determined to bridge the gap between conventional healthcare and the real needs of first responders, Dr. Sheinberg co-founded Sigma Tactical Wellness. His vision was clear: create a program that brings together advanced cardiovascular diagnostics with the cultural understanding of those who wear the badge. Sigma is more than a company—it’s the culmination of his experience, passion, and unwavering commitment to the men and women who run toward danger when others run away.
Now part of TeleMed2U, Sigma Tactical Wellness continues to lead the way in advanced cardiac screening and prevention. Our work is grounded in science, strengthened by service, and driven by the belief that every officer deserves a fighting chance—not just in the line of duty, but in life.
At Sigma, we’re not just protecting hearts. We’re honoring the people behind the badge.

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
To date, Sigma Tactical Wellness has served over 25,000 emergency responders across the United States. Sigma continues to set the standard in cardiovascular disease detection within the public safety sector.
