About Saint Apollonia
Not your typical agency.
We were built from the ground up for one thing — to take ambitious companies and scale them into market leaders. No fluff. No guesswork. Just growth.
Meet Our Founders
Built on a Legacy. Driven by Results.
Saint Apollonia wasn't built in a boardroom — it was forged over decades of real-world advertising, brand-building, and relentless dedication to growth.
With over 50 years of advertising experience, Harry Harrison has worked with some of the most recognized brands in America — and helped build a few of them himself.
Harry's career began at Neiman Marcus, where he honed his craft as Creative Director before joining the prestigious firm Bozell & Jacobs. There, he led campaigns for American Airlines, Texas Instruments, Holiday Inn, Cessna, E-Systems, and Pizza Inn.
He co-founded Harrison Simmons, earning the trust of Pearle Vision, Don Pablo's, and Associates First Capital Corporation — then launched Harrison Creative, delivering results for AT&T, Siemens, Texas Land and Cattle, and Culwell & Son.
When his son set out to reimagine the dental experience, Harry committed everything — channeling his full creative and strategic weight into building MINT Dentistry. The results: MINT grew to over 100 locations, becoming one of the largest private dental practices in the United States.
Dr. Field Harrison is the visionary behind MINT Dentistry — a brand that redefined what patients expect when they walk into a dental office.
With a relentless focus on patient experience, bold branding, and scalable systems, Dr. Harrison transformed a single practice into a nationally recognized dental powerhouse with over 100 locations — one of the largest private dental practices in the United States.
Now, alongside his father, Dr. Harrison leads Saint Apollonia with the same ambition that built MINT: the belief that the right strategy, creative, and execution can take a brand from concept to category leader.
The Agency Behind the Growth
The proven playbook. Now available to you.
Saint Apollonia is the in-house advertising and management firm that powered MINT Dentistry's rise to over 100 locations. Now, Harry and Dr. Field Harrison are opening the door to new partners — bringing that same proven playbook to businesses ready to scale.
If you're ready to grow, we know the way.
Our Mission
Growth is the only metric that matters.
Saint Apollonia was built with a singular focus: exponential growth for companies that are ready for it. We're not an agency for startups finding their footing. We're the team you call when you have momentum and need someone to pour fuel on the fire.
We work exclusively with medium to large companies because that's where our methodology — the intersection of bold creative, elite media buying, and proprietary data infrastructure — delivers the most profound results.
We've been here before. We know what it takes to open 10 locations, then 20, then 60. We know what a brand needs to sound like, look like, and spend like to dominate a market.
This is what we do. This is all we do.
What We Stand For
The principles that drive us.
Every decision we make — creative, strategic, financial — runs through these values.
We don't chase trends — we identify them before they exist. Our team is constantly scanning culture, technology, and consumer behavior.
Every strategy we build is backed by data, tracked in real time, and optimized relentlessly. We built our own systems to make sure nothing falls through the cracks.
Safe advertising is invisible advertising. We push our clients to be remarkable — because in a crowded market, the only way to win is to refuse to blend in.
Everything we create is designed to scale. What works at one location needs to work at sixty. We build for that from day one.
You always know exactly where your money is going and exactly what it's doing. Full visibility into every dollar, every campaign, every result.
Great work is non-negotiable. From a logo mark to a national media buy, we hold every output to the same uncompromising standard.
Our Story
How we got here.
Founded on a simple belief
Saint Apollonia was founded by marketers tired of agencies that over-promised and under-delivered. We set out to build something different — a team with the firepower of a large agency and the accountability of a true growth partner.
OriginsAssembling the team
We recruited the best strategists, creatives, developers, and media buyers in the industry — people who had built and scaled brands at the highest level. Then we built the data infrastructure that ties it all together.
Team InfrastructureMINT Dentistry: 1 to 100+
When MINT Dentistry came to us with one location and a vision to redefine dental care, we built everything — brand identity, digital presence, media strategy, and a scalable marketing infrastructure. The result: over 100 locations opened nationwide.
Case Study: Multi-LocationA proven engine for growth
Today, Saint Apollonia is a full-service powerhouse — branding, digital, design, web development, traditional media, and the highest level media buys in the industry. We partner with companies that are serious about scale.
Full Service GrowthWhy Saint Apollonia
What makes us different.
Our in-house development team built marketing tracking infrastructure from scratch. We know exactly where every dollar goes.
We operate at the top tier — TV, OOH, radio, digital. Our relationships get clients access and pricing that most agencies can't offer.
No outsourcing. Strategy, creative, development, media, data — all under one roof. Faster execution. Tighter integration.
Multi-location. Multi-market. Multi-channel. We've done it before and built systems specifically designed to handle it.
By the time a trend hits mainstream marketing chatter, our clients have already been executing it for months.
Our Culture
We're not a vendor. We're your growth partner.
The best work happens when the agency and client are locked in together — sharing the same goals, the same urgency, and the same hunger to win.
We're selective about who we work with because we go all in. When we take on a client, we're not clocking hours — we're invested in your outcomes. Your growth is our reputation.
