Joshua D. Mellberg does not talk much about disruption. He talks about durability.
In an industry known for fast growth and faster promises, Mellberg has spent more than two decades focused on something less flashy: building systems that hold up over time. His career in retirement-income planning has unfolded gradually, shaped by observation, structure, and a steady belief that clarity matters more than speed.
Today, Mellberg is President and CEO of Secure Investment Management (SIM), a tech-forward advisory platform recognized on the Inc. 5000 list in 2024 and 2025. But the way he leads now is rooted in habits formed long before SIM existed.
Early Patterns That Still Show Up
Mellberg grew up moving across the United States, spending most of his time in Tucson, Michigan, and Louisiana. That constant movement taught him to pay attention quickly.
“When you move a lot, you learn to read situations fast,” he has said.
From a young age, he showed an interest in building things. He sold items on eBay as a teenager. While attending Western Michigan University’s Haworth College of Business, he started a business designing and building custom dorm-room beds.
“I was always looking for what was missing,” Mellberg has said. “That hasn’t really changed.”
Right after college, he earned his Life and Health Insurance license. That step launched his career in retirement-income planning, an area he found meaningful but often poorly explained.
Choosing Clarity in a Complex Industry
Early in his career, Mellberg noticed that many people struggled to understand the products and strategies being discussed with them.
“It wasn’t that the information didn’t exist,” he has said. “It just wasn’t being explained well.”
Instead of leaning into complexity, he focused on translation. He spent years learning how to explain technical ideas in simple language. Over time, that skill became central to how he worked with both clients and advisors.
Education became a responsibility, not a marketing tactic.
That philosophy led him to found J.D. Mellberg Financial in 2005.
Building a Firm That Could Scale
As J.D. Mellberg Financial grew, Mellberg avoided improvisation. He believed growth without structure created fragility.
“I don’t like guessing,” he has said. “I like systems.”
He adopted clear goal-setting practices and relied on measurable performance indicators.
“I set SMART goals and KPIs that actually match the work,” he has said.
The firm earned seven consecutive appearances on the Inc. 5000 list during his leadership. Mellberg attributes that consistency to process, not momentum.
He also implemented the Entrepreneurial Operating System (EOS) to manage priorities.
“It’s the boulders, rocks, and pebbles,” he has explained. “If you don’t handle the big things first, everything else becomes noise.”
By 2020, J.D. Mellberg Financial had reached a point of maturity. Mellberg completed a majority sale and began planning what came next.
Pressure Tests Reveal Weak Spots
When the pandemic disrupted in-person meetings, Mellberg saw it as more than a temporary challenge.
“The pandemic shifted the industry,” he has said. “It exposed what wasn’t working.”
His team rebuilt their process into a fully virtual model that reaches more prospects without sacrificing consistency.
“That change actually put us in front of more people,” he has said.
The experience reshaped how Mellberg thought about scale and access. It became the blueprint for Secure Investment Management, which he founded in 2022.
Designing SIM for How Work Happens Now
SIM was built to support advisors with modern tools, repeatable processes, and clear communication. Mellberg serves as President and CEO and holds a Series 65 Investment Adviser Representative license, with registrations in Arizona, California, Colorado, Florida, and Texas.
The firm earned Inc. 5000 recognition in both 2024 and 2025, including a top national ranking in 2025.
Mellberg is careful about how he frames success.
“Growth is a result,” he has said. “It’s not the starting point.”
Leadership Without the Need to Be Certain
Mellberg does not claim to lead solely by instinct. He leads by surrounding himself with people who challenge him.
“I don’t have self-doubt as long as I’m surrounded by fantastic people,” he has said.
He relies on coaches and advisors for objective feedback.
“I want people who will tell me when I’m wrong,” he has said.
That approach shapes how he mentors advisors and builds teams, emphasizing long-term thinking over short-term wins.
Education as a Consistent Thread
Education has remained a core part of Mellberg’s work. He has hosted retirement-planning programming on Arizona PBS and frequently speaks at industry events.
His goal is straightforward.
“If you can’t explain it simply, it’s not useful,” he has said.
He avoids predictions and hype, focusing instead on foundational understanding.
Redefining Balance Over Time
Earlier in his career, Mellberg measured progress by output. Over time, that changed.
“Every year, I schedule more time away,” he has said. “You have to step back so the business doesn’t take over.”
He lives in Tucson, Arizona, with his wife and son. Outside of work, he enjoys traveling with his family, staying active, reading business and biography books, and mentoring advisors.
He has also been a member of YPO Scottsdale since 2014, where he connects with other business leaders.
Thinking Beyond the Quarter
Joshua D. Mellberg does not frame his career as a series of big moments.
“It’s been perseverance, self-discovery, and education,” he has said.
In an industry driven by urgency, Mellberg has built something quieter and more durable—by thinking in decades, not quarters.
