Emergency care.
Sales discipline.
Useful systems.
I’m Preston Willis. I work with the fire departments and EMS agencies that put medical technology to use. I bring that field perspective to market research, commercial planning, and practical systems built through Willis Innovations.

Make the next move useful.
For teams bringing useful technology to emergency care and public safety. A focused engagement can turn a broad growth question into a buyer map, a pilot brief, or a working research system.
Partner & pilot planning
Turn an emerging idea into a practical set of questions: who operates it, who pays, what must be approved, and what would make the pilot worth continuing.

Experience with the people
who put equipment to work.
My Stryker Emergency Care work spans fire departments, municipal and private EMS agencies, law enforcement, and hospital accounts across a multi-county Georgia territory.
I manage the full sales cycle, from account planning and demonstrations to in-service training and post-sale support. That experience informs how I approach adoption, relationships, and the work after a purchase.

Discuss a consulting project01 / The person
A few things that connect the dots.From the operating room
to the next useful idea.
In 2017, I worked beside operating-room teams at Stryker, troubleshooting endoscopy equipment during procedures and helping staff learn the technology.
I moved into emergency-care sales in 2018. In 2021, I added volunteer fire and medical response with Oconee County Fire Rescue. Today, I both explain equipment to the people who depend on it and stay involved in the work firsthand.
That interest in how things work also led me to build CaliberAtlas. I chose to keep its core tools free and make the sources and assumptions visible. People can use the reference, inspect the methods, and question the results.

Willis InnovationsCuriosity,
put to work.
Through Willis Innovations, I choose the problems, direct the research and product work, and decide what is ready to publish. These are examples you can explore.
CaliberAtlas
From scattered ballistics data to a transparent decision tool. The challenge: making cartridge information useful while keeping its sources and assumptions inspectable.
- My role
- Builder and operator: research direction, product decisions, and quality standards.
- Today
- A live, free reference with cartridge comparisons, a ballistics calculator, and printable range cards.
- See the result
- Published methods and accuracy comparisons show how calculations relate to manufacturer data.
Mutual Aid Supply Co.
A firehouse-born apparel brand for the public-safety community. The brief: everyday gear that reflects the people doing the work, with a clear connection to service.
- My role
- Brand direction and commerce, informed by my volunteer fire and EMS experience.
- Today
- A live apparel storefront with an early give-back program.
- See the result
- A published collection, founding story, and crew-support commitment. Program results will be published as they develop.

03 / Practical AI coaching
Curiosity needs a process.Bring one task.
Build a way forward.
I help founders and business teams turn everyday research and administrative tasks into AI workflows they can understand, check, and reuse.
The habit I teach: review the result. Give AI a clear task and useful source material. Check its output, question its assumptions, and keep a person responsible for the final decision.
A working session with a concrete aim.
Start with one non-sensitive research question or repetitive administrative task. We can map the inputs, walk through an approach, and identify where a person needs to check the work.
The aim is a written workflow outline you can reuse: inputs, steps, review checks, and a next experiment. Any prototype or ongoing work would be scoped separately.
These are independent conversations through Willis Innovations. We start by confirming fit and scope.

From a question to something you can use.
These are my own builds. They show the process I bring to coaching: a useful problem, AI-assisted work, human review, and a result you can inspect.
Making technical research usable.
- The problem
- Cartridge specifications are scattered across sources and hard to compare consistently.
- AI assistance
- Organize source material and help develop the reference and comparison tools.
- My review
- Check results against published methods and reference data. Keep sources, assumptions, and limits visible.
- The result
- A free reference with cartridge comparisons, a ballistics calculator, and printable range cards.
Turning public records into a useful search.
- The problem
- Official contractor rosters can be difficult for a homeowner to navigate by location.
- AI assistance
- Help organize public roster information and build a county-based search experience.
- My review
- Keep listings traceable to official state sources and make coverage limits visible.
- The result
- A free directory that lets homeowners search by county or browse official state-roster listings.
