From Career Nanny to Agency Owner: Why I Built Premier Nanny Source

People sometimes ask how I ended up running a nanny agency, as if it were a strange career turn. To me it has always felt like the most natural thing in the world, because I did not start in an office thinking about staffing. I started on the floor, with the blocks and the snack negotiations and the bedtime routines. I was a nanny first, for years, and everything about how this agency works comes directly from what those years taught me. Let me tell you the story, because it explains why we do things the way we do.

I learned this work by living it

Before I ever placed a single nanny, I was one. I spent years inside families' homes, caring for their children, becoming part of their daily lives, and learning what this work actually demands. Not the version in a job description, but the real thing: the patience, the judgment, the small daily acts of love and attention that good childcare is genuinely made of. I learned what makes a placement thrive and what quietly makes one fall apart, because I lived both.

That experience changed how I see everything about this industry. When I evaluate a candidate now, I am not reading a resume from the outside. I am recognizing, from the inside, the qualities that actually matter, because I know what it feels like to be the person on the floor at the hardest moment of the day.

I saw what went wrong, again and again

Working inside families' homes, I also saw the patterns that broke good arrangements. I watched wonderful caregivers leave because they were quietly underpaid or never appreciated. I saw families hire in a panic and regret it. I noticed how often the mismatch was not about a bad person, but about a bad fit or a careless process that nobody had thought through. And I kept thinking, over and over, that so much of this pain was preventable.

I also experienced firsthand how it feels to be a caregiver who is treated as a true professional, with respect, fair pay, and clear expectations, versus one who is treated as an afterthought. That contrast stayed with me. It became the foundation of everything I would later build.

The conviction that started the agency

Great childcare relationships are not luck. They are the result of careful matching, honest expectations, fair treatment, and real support on both sides. I had seen enough to know it could be done deliberately and done well, and that nobody was doing it the way I believed it should be done. So I decided to.

Why I built Premier Nanny Source the way I did

When I started this agency, I built it around everything those years had taught me. I built our vetting to be rigorous, because I knew exactly which qualities matter and how easily a thin process misses them. I built our matching to be careful and personal, because I had seen how much fit matters and how badly a careless pairing can go. And I built our whole approach to honor caregivers as the skilled professionals they are, because I remembered precisely how it felt to be one.

I wanted to create the agency I would have wanted to work with as a nanny, and the agency I would trust as a parent. Those two perspectives, the caregiver's and the family's, live in everything we do, because I have genuinely stood in both places.

What this means for the families we work with

When you work with us, you are not working with someone who studied this industry from a distance and decided it looked like a good business. You are working with someone who did the actual job, for years, and built this whole agency out of what that work taught her. Every guide I write, every candidate we screen, every match we make is informed by real time spent on the floor with real children in real families.

That is the difference I hope you feel when you work with us: this is not theory for me. It is my life's work, built from the inside out, with deep respect for both the families and the caregivers we bring together. If that resonates with you, I would love to help with your family. Reach out anytime, and you will be talking with people who genuinely understand this work, because we have lived it.

What being a nanny taught me that no business course could

People who come to this work from business backgrounds often understand operations and miss the heart of it, and I came at it from the opposite direction, which I think is a real advantage. The years I spent as a nanny taught me things you simply cannot learn from the outside. I learned what genuine patience looks like at the end of a long, hard day. I learned how a child's trust is built slowly, in small consistent moments. I learned what families actually need versus what they think they need, and how often those differ. And I learned, from the inside, exactly what makes a caregiver feel respected or disposable. All of that lives in how I run this agency now, because I am not guessing at any of it.

The kind of agency I wanted to build

Knowing both sides so intimately, I was determined to build something that honored both. An agency where caregivers are treated as the skilled professionals they are, paid fairly, set up to succeed, and genuinely supported, because I remember being one. And an agency where families get the careful matching, honest guidance, and rigorous vetting they deserve, because I understand how much rides on this decision and how scary it can feel. I did not want to build a transactional placement mill. I wanted to build the agency I would have trusted as a nanny and relied on as a parent, and that double perspective is the whole foundation of how we work.

Frequently Asked Questions

Who founded Premier Nanny Source?

Premier Nanny Source was founded by Rhiannon Sergienko, a former career nanny who spent years caring for children inside families' homes before building the agency. That firsthand experience, knowing the work from the inside as both a caregiver and an advocate for families, shapes how the agency vets, matches, and supports both nannies and the families they serve.

Why does a founder's nanny background matter?

Because it means the vetting and matching come from lived understanding rather than theory. Someone who did the actual job for years recognizes the qualities that truly matter in a caregiver, understands what makes placements last or fail, and knows firsthand how it feels to be treated as a professional, all of which informs a better, more genuine process for families and caregivers alike.

What makes Premier Nanny Source different from other agencies?

An approach built from the inside out by someone who was a career nanny first. That means rigorous vetting informed by real experience, careful and personal matching, and a genuine commitment to treating caregivers as skilled professionals, which in turn helps attract and keep the kind of caregivers families most want.
