About DGS Immersive
DGS Immersive was built around a deeply held belief: The people who run toward danger deserve the most realistic, thoughtful preparation possible — and a proven path to restoring operational readiness when it matters most.
With almost two decades of experience planning and executing large- and small-scale immersive experiences, we have developed a rare depth of understanding about what works in high-stakes environments and what doesn’t. That experience informs everything we do.
We work with military units, law enforcement agencies, fire services, and emergency medical teams. Our support is fully portable and self-sustaining — we integrate into your existing structures, wherever you are, with minimal burden on your resources or manpower.
Our Two Areas of Practice
Training for Operational Readiness
We create immersive, scenario-based training events tailored to your team’s specific objectives. With nearly two decades of experience and a fully self-contained operation, we bring professional role players, film-quality moulage make-up, and carefully constructed environments directly to you — wherever you are in the country. The result is a training experience that puts your people under real pressure, in a safe and controlled setting, building the muscle memory and decision-making capacity that only comes from doing it for real.
Restoring Readiness After Trauma
After a critical incident, the return to full operational effectiveness is not something that happens on its own. DGS Immersive supports this process by working directly with the clinicians responsible for a team member’s recovery.
We do not initiate this work independently. Our role is to build and deliver the exposure scenarios prescribed by the psychologist, psychiatrist, social worker, occupational therapist, or other regulated professional overseeing care. The clinician leads. We execute.
This model ensures that every scenario is clinically appropriate, therapeutically sequenced, and aligned with the individual’s recovery goals — while drawing on our expertise in realistic, immersive environment design.
Our Mission
To build and restore readiness in the people who protect and serve our communities — through realistic training, clinician-partnered support, and an unwavering commitment to those who carry the weight of the work.
Meet the Founder
Jennifer Mackey — Founder & Director of Operations, DGS Immersive
Jennifer Mackey didn’t start at the top of the immersive training world. She started in the scenarios.
Early in her career, Jennifer worked as a role player in large-scale military training exercises — on the ground, in character, watching firsthand as realistic, pressure-filled scenarios transformed the performance and confidence of the people being trained. What she saw convinced her that this kind of training mattered deeply, and that she wanted to be more than a participant in it.
Over the next eight years, she stepped into the role of scene director, designing and running the scenarios that put trainees under pressure. She learned what worked, what didn’t, and what separated a training exercise that changed people from one that was simply checked off a list. From there, she moved into leading teams of scene directors across multiple exercises simultaneously — developing the operational instincts and leadership depth that only comes from managing complexity at scale. In the final six years of her time at her previous organization, Jennifer took full ownership of exercise planning and logistics for the role player division: scenario design, moulage makeup planning, casting, travel coordination, and training. Every moving part of what makes immersive training function at a high level passed through her hands.
In 2023, Jennifer founded DGS Immersive with a clear and specific purpose. She had watched world-class immersive training be delivered almost exclusively to military clients — and she believed that the men and women who serve as police officers, firefighters, paramedics, and security personnel deserved the same standard of preparation. These are people who have dedicated their lives to the service of their fellow citizens, often at significant cost to their own physical and psychological safety. Jennifer founded DGS to change that — to make elite immersive training accessible and affordable for the first responder community, and to build something that takes seriously the responsibility of protecting the people who protect everyone else.
That mission is personal. Jennifer understands that preparing someone mentally and emotionally for the realities of their role isn’t a nice-to-have — it’s a form of protection. It’s why DGS doesn’t just train teams for operational readiness, but also supports them in restoring that readiness after critical incidents take their toll.
Her leadership style reflects everything she believes: compassionate enough that her team knows they matter, and authoritative enough that they know she means it.
