Sentinel Silver's Story
Honoring a generation that sent us to the moon.
Sentinel Silver, LLC provides security, safety, and technology support for older adults and the families who love them. This page tells the story behind that work: a family, a promise, and the standard we keep in your home.
July 20, 1969
My grandparents gathered in their living rooms across Western Maryland, along with 600 million people worldwide, to watch Commander Neil Armstrong take humanity's first steps on the Moon.
My grandparents Dick and Maureen, with Maureen's parents. Western Maryland, 1969. The generation who watched.
Throughout my childhood, my grandfather Dick Hann spoke most proudly about that warm July night in 1969. Not only the accomplishment itself, but the audacity of it. He fought a war, won, and then America sent a man to the Moon. Can you imagine that moment for that generation? It was the best that America ever was.
Small-town Americans, humble men and women from places like Hagerstown, Maryland, had built technology sophisticated enough to send three astronauts 240,000 miles through space and bring them home safely.
My grandfathers understood that kind of precision. Dick spent World War II defusing land mines across Europe, work where one mistake meant death. Scotty Miner, a Chief Master Sergeant in the Air Force, spent his career overseeing aircraft maintenance so that every plane that took off brought its crew home safely.
Buzz Aldrin at the flag, Sea of Tranquility, 1969. Neil Armstrong held the camera, which is why he appears in almost no surface photos.
They understood what NASA understood: when lives depend on your work, you don't cut corners. You don't rush. You get it right.
That standard became the foundation of Sentinel Silver.
Here is what troubles me. The smartphone in your pocket today carries roughly 100,000 times the computing power of the Apollo Guidance Computer. Yet when older adults struggle with technology, there is no Mission Control to help them.
My grandfather Dick with his iPad. More computing power than Apollo 11, but no Mission Control to call.
No patient voice guiding them through.
No one who treats their confusion as a design problem, not a personal failure.
The Reason This Company Exists
In my grandmother Maureen's final months, I asked her a question. "Do you remember watching the Moon Landing?"
She didn't.
A memory she had recalled with such joy throughout my life was gone. Alzheimer's took it from her before she passed away peacefully, surrounded by family, on July 16, 2025. She was 92.
One grandmother gone. Another fading.
My grandmother Joyce has lived in a Washington County memory care community since 2023. Her memories, too, are fading. At the beginning of her dementia journey, a scammer reached her by phone and took more than $3,000 from her. We changed her phone number after 40-some years.
That feeling, learning someone had exploited my grandmother, was one of the most intense angers I have ever known. Perhaps because I felt helpless. Perhaps because I was angry at myself for not protecting her before it happened.
I should have protected her. The way my grandfather Scotty would have protected his beloved wife, Joyce.
So I built the company that should have existed the day that phone rang.
Sentinel Silver is that Mission Control.
The same standard of precision, patience, and care that built the space program, brought to your parents' kitchen table. Because they deserve nothing less.
Technology is the excuse. The relationship is the service.
Our Why
Sentinel Silver runs on a promise, written down in our founding documents and kept in every home we enter.
"I will treat every older adult I serve the way I wish my grandparents had been treated when they needed help with technology."
The Sentinel Silver Mission
To honor our grandparents by treating every older adult as family, using technology as the bridge for relationships where safety comes first, wisdom flows both ways, and dignity is never compromised. Through direct service and peer-reviewed research, we prove that sacred obligation is a business model.
The Sentinel Silver Vision
To change how the world thinks about serving older adults, proving that relationships built on safety and sacred obligation outperform transactions, and ensuring that every technology company that comes after us feels the pressure of our example.
We are translators of inherent capability. We translate "I can't" into "I just did." We are not repairing people. We are revealing capability that was never absent.
Three promises carry that mission into every visit. Each one grew from a member of the family you are about to meet.
We operate on your time. We never rush. We never sigh. We never watch the clock. Ask us anything, as many times as you need.
From Dick, a WWII veteran who defused land mines and remains the gentlest soul I have ever known.
We speak plain English and strip away the jargon. If it isn't straightforward, it isn't done.
From Joyce, who served schoolchildren for decades with warmth and clarity and never overcomplicated a thing.
We show you the screen. We explain the why. No secrets, no surprises, no fine print.
From Maureen, a businesswoman who faced truth head-on and expected the same from everyone around her.
The Foundation of Sentinel Silver
The seven people who made this mission possible. Nobody built Sentinel Silver to chase a market opportunity. A grandson built it to honor his family.
It began in Hagerstown, Maryland, a small city in the hills of Western Maryland where generations put down roots and stayed. This is where Dick and Maureen raised their family, where Scotty and Joyce built their lives, and where I grew up.
Western Maryland does not teach you to chase trends or cut corners. It teaches you to show up, to keep your word, and to take care of your neighbors. My family gave me something money cannot buy: wisdom. Sentinel Silver exists to pass their wisdom forward, and every decision passes through one filter.
Would my grandparents be honored? Would my parents approve? Would my children be proud to carry this forward?
Meet the seven. Each represents a pillar of Sentinel Silver. Open any name to see their photo and read their story.
July 23, 1925 to December 22, 2020
My grandfather Dick served in the Army in World War II and spent the war defusing land mines across Europe, work where one mistake meant death. After the war, he spent more than 35 years keeping Hagerstown's lights on as an engineer at the Municipal Electric Light Plant. Quiet. Steady. Reliable.
His quiet strength taught me that presence matters more than words. He never rushed. He never raised his voice. He was there. Pap was the gentlest soul I have ever known.
We do not sigh. We do not watch the clock. We sit beside you, never above you, and move entirely at your pace.
August 23, 1932 to July 16, 2025
My grandmother Maureen was a businesswoman and the rock of our family. She showed me that grace under pressure is not a performance. It is a practice. Her fifteen-year journey with Alzheimer's taught our family what preserving dignity truly means. Even as her memories faded, her grace remained.
She never pretended things were easier than they were. She faced truth head-on and expected the same from everyone around her.
We verify truth. We show you the screen. We explain the why behind everything. No hidden fees. No fine print.
July 17, 1937 to November 28, 2009
My grandfather Scotty spent his Air Force career at the 167th Airlift Wing overseeing aircraft maintenance, so that every plane that took off brought its crew home safely. He understood what NASA understood: when lives depend on your work, you do not cut corners. You do not rush. You get it right.
That standard became the foundation of Sentinel Silver.
We prepare before we arrive, we double-check our work, and we treat your technology with the same care he brought to every aircraft.
Born May 9, 1941
My grandmother Joyce, my sole living grandparent, grew up in Washington County as one of twelve children in a family of American dairy farmers. She brought that tireless spirit to everything she did and became one of the most beloved cafeteria workers in the history of Washington County Public Schools.
Today she lives in memory care. At the beginning of her dementia journey, a scammer reached her by phone and took more than $3,000 from her. Protecting people like her is the reason Sentinel Silver exists.
We strip away the jargon. If it is not straightforward, it is not done. We deliver help with the warmth and sincerity she brought to every child she served.
My mother Colleen spent fifteen years as the fierce advocate and caregiver for her parents, Dick and Maureen. This was not passive caregiving. She fought systems that tried to dismiss them. She challenged policies that prioritized efficiency over dignity. She advocated relentlessly and fearlessly, regardless of time, cost, or inconvenience. Because what is right is right.
Thousands of hours. Emotional exhaustion. Financial burden. Personal sacrifice. She paid it all, because they were worth it.
We walk alongside people rather than leading them, and we fight for what is right regardless of cost or inconvenience.
My father, Bryan C. Miner, gave me roots: the foundation upon which everything else could be built. He taught me that trust grows from reliability. Showing up when you say you will. Respecting a person's home. Delivering on your word without excuse or delay.
You do not advertise it. You do it.
We arrive on time, we respect your home, and we bring a no-nonsense guarantee to every appointment.
My stepfather, Leon Bowers, showed me that family grows through choice and commitment, not blood alone. He provided the strategic guidance and strength that allowed this mission to take root, and he taught me to build systems that are robust, defensible, and made to last.
Not quick patches. Legacy architecture.
We build protections designed to keep you safe for the long haul, never a quick patch.
Getting it right, without needing recognition:
Dick defused mines so soldiers could walk safely.
Scotty maintained aircraft so crews could fly home.
Maureen faced Alzheimer's for fifteen years with grace.
Joyce served children for decades with warmth that filled every room.
Colleen fought for her parents' dignity for fifteen years.
Bryan showed up, every time, without fail.
Leon built systems designed to last.
None of them needed recognition. They needed to get it right. Sentinel Silver carries that standard forward.
Where Our Methods Come From
We built Sentinel Silver from day one to do two things: help older adults with technology, and work with universities to study what works.
Researchers have identified promising practices for helping older adults with technology. But long-term proof does not exist yet. Most studies measure success in weeks or months, not years. Sentinel Silver intends to fill that knowledge gap, and our long-term goal is to close it alongside a Maryland university.
The work your family sees and feels. Sitting beside your loved one, patiently teaching. One-on-one coaching in the home. Ongoing partnerships inside senior living communities. Scam intervention and recovery. Photo digitization and legacy preservation.
What we are building behind the service. The infrastructure for academic partnerships, the methodology, and the evidence, so that technology support for older adults becomes measurable and provable, and then we share what we learn with families everywhere.
Most companies guess whether their methods work. Sentinel Silver measures, improves what falls short, and aims to publish what we learn. That is a legacy worth building.
The Person Behind the Promise
Ryan R. Miner, MBA. Founder of Sentinel Silver and your Personal Technology Guide.
I am Ryan R. Miner, the founder of Sentinel Silver. I grew up in Hagerstown and live in Gaithersburg. I hold an MBA, and I am licensed, background-checked, and insured, because families trust Sentinel Silver inside their homes.
I also know what it feels like when nobody takes the time to learn how you learn. In 1991, doctors diagnosed me with Attention Deficit Disorder. I was in first grade. Six years old. I spent years in classrooms that taught in ways that did not work for me. Not because I couldn't learn. Because nobody took the time to discover how I learn best.
That experience became the foundation of how Sentinel Silver works. The people we serve are not struggling because they are incapable. They are struggling because nobody has ever taken the time to understand how they learn. Sentinel Silver refuses to make that mistake.
So before we touch a single device, we talk. About your story, your style, your history with technology, and what you want it to do for you. We teach technology. The older adults we serve teach lifetime wisdom. That exchange is the privilege of this work.
