The search starts the second you say go.
DENNIS is a community safety platform for locating missing at-risk persons. Born in the autism community and open to everyone — individuals with autism, cognitive or developmental disabilities, dementia or Alzheimer's, and any family who wants a community ready to search. One press starts the search with the pre-built profile, and the family provides the details of the moment — clothing, last seen — while help is already moving.
What It Is
Three alerts. One community. Zero cost.
When a loved one goes missing, DENNIS notifies nearby verified volunteers, businesses, and partners in real time — with the information they need to help safely and immediately.
Elopement Alert
For wandering events — the moment an at-risk person leaves a safe place, the search starts with their pre-built profile: photo, communication needs, attractions and fears, and how to approach safely.
Missing Person Alert
For any missing child or endangered adult. Nearby helpers see who to look for and where, while the family adds the details of the moment as help is already moving.
Assistance Alert
For urgent non-disappearance emergencies — when a family needs extra eyes, hands, or calm help nearby, fast.
Simple enough for the hardest day of your life.
Every screen assumes shaking hands and no time to read. Everything that can be set up in advance already is. When it matters, simple prompts guide you through.
For Families & Caregivers
Built by a family that lives this — for families like yours.
Autism, Down syndrome, dementia or Alzheimer's, a brain injury, a child who bolts, a parent who gets turned around — if someone you love could go missing, DENNIS is for you. No diagnosis required to join.
- A secure profile you build once — photos, medical needs, communication style, places they're drawn to — ready the second you need it.
- One press starts the search; you add the details of the moment while nearby help is already moving.
- Every emergency feature is free. Cost should never decide whether a family gets help.
For Volunteers, Businesses & Organizations
Your community, ready to answer.
- Verified volunteers get real-time alerts near them, with safe-approach guidance for each person's needs.
- Every volunteer is identity-verified and background-checked before their first search.
- Businesses become safe locations and lookout points; organizations amplify alerts to their people.
For First Responders & Partner Organizations
A force multiplier for the people who answer the call.
DENNIS does not compete with or replace our first responders — think of it as a force multiplier. Law enforcement, fire, EMS, dispatch, and SAR teams get structured, actionable information from the first minute: profile, last-known location, and a coordinated volunteer picture. We are looking to work closely with federal, state, and local agencies to help amplify DENNIS's effectiveness and to streamline with the government programs our families already need and use. DENNIS is designed to complement public alerting systems — it is not affiliated with, endorsed by, or operated under any government agency.
- Pre-built subject profiles with safe-approach guidance, available on scene in seconds.
- A live picture of where volunteers have looked — so official resources go where they're needed most.
- ASD, disability, and eldercare professionals and care organizations can register to support families and responders during events.
For Service Providers, Care Facilities & Local Businesses
Be found by the families who need you.
Therapists, caregivers, safety product companies, care facilities, memory care communities, and specialized services will be listed in the DENNIS directory — where families look first. And the directory isn't just for care: every local business that wants to support the mission belongs here — car dealerships, swim schools, martial arts studios, camps, educational resources, and more. It's another way to reach the families in your own community, and to strengthen not just your visibility but your community ties. Directory listings open with the public release.
Get on the Directory ListEvery emergency feature is free for families. Sponsors help make it possible.
When a child wanders from home or a grandfather with Alzheimer's walks out the door, the response that brings them back doesn't fund itself. Sponsors make it possible — vetting the volunteers who answer the call, keeping the alerts and maps running, and growing the search network in every community DENNIS reaches. Whether you give dollars, services, or products, you become part of every safe return — and your community will see it: on our website, at our events, on our Hero Wall, and in the stories we tell about the people who stood with us.
