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.

Through Willis InnovationsFor 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.
Map agencies, decision makers, purchasing routes, and local priorities. Make it clear who the product serves and what a credible first conversation needs.
A focused market-entry briefTurn 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.
A pilot scope and decision criteriaBuild workflows that turn public information into useful account research. Keep source links, human review, and a clear next action close to the work.
A working tool and usable handoffPublic-sector sales record
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.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.

From scattered ballistics data to a transparent decision tool. The challenge: making cartridge information useful while keeping its sources and assumptions inspectable.

04 / How I work with AI
Curiosity needs a process.For founders and business teams exploring AI in everyday research and administration.
One example from my own work. For CaliberAtlas, I use AI to help organize source material and develop tools, then check the results against published methods and reference data. I own the scope, review, and publication decisions. Read the methodology
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.
