Who Is Dan Greiner
Dan Greiner is best known as the longtime husband and business partner of Lori Greiner, the entrepreneurial powerhouse on Shark Tank. But Dan’s identity extends far beyond that. A financial expert with a low profile and a deeply analytical mind, Dan has been a steady and strategic force behind the scenes for decades. With a background in corporate finance and operations, he brings a complementary set of skills that balances Lori’s creativity and boldness as an inventor and television personality.
Dan prefers privacy over publicity. He rarely gives interviews, doesn’t have a splashy social media presence, and typically avoids media coverage. But his impact is deeply felt within the inner workings of Lori Greiner Companies.
How Dan Met Lori In Chicago
Dan and Lori’s love story began in the 1990s, long before Shark Tank and television fame entered the picture. The two first met at a bar in Chicago’s Lincoln Park neighborhood called Kincade’s. At the time, Lori was just beginning to pursue her ideas as an inventor, while Dan was working a steady corporate job. They quickly connected and began dating, laying the foundation for what would become a lasting personal and professional bond.
Their early relationship revolved around ambition, vision, and support. Dan recognized Lori’s entrepreneurial spark and stood by her as she took her first bold steps into the world of business and product creation.
Inside Their Early Partnership
The couple’s entrepreneurial journey took off with Lori’s first big idea—a plastic jewelry organizer. It may sound simple, but this product was the start of an empire. Lori came up with the concept and had the vision, but it was Dan who sat down and sketched out the design. More importantly, he backed her when it mattered most.
Together, they took out a sizable loan to fund the initial production. Dan believed in Lori’s ability to succeed, even when the risks were high. Their teamwork was evident from the start—Lori was out front promoting the product, while Dan played a key supporting role. During in-store demos at JCPenney, Dan even pretended to be a customer to help draw crowds and boost sales.
Dan’s Corporate Career Before Joining Lori
Before diving into entrepreneurship full-time, Dan Greiner built an impressive career in the corporate world. He worked at Grant Thornton LLP from 1987 to 1990, where he gained experience in consulting, auditing, and tax services. He then moved to Bell & Howell, a well-known technology and services company, where he served as a division controller for eight years.
His career path was steady, traditional, and rooted in numbers and management. But Dan wasn’t afraid to shift directions when opportunity called. When Lori’s first invention gained traction, Dan made a bold decision that changed the course of both of their lives.
Joining Lori Greiner Companies
In 1996, Dan left his job at Bell & Howell and officially joined Lori’s growing business as vice president. The company, For Your Ease Only, Inc., would eventually evolve into Lori Greiner Companies, home to her many product lines and brand ventures.
Dan took on the role of CFO and COO, overseeing the financial and operational aspects of the business. His presence allowed Lori to focus on product development, marketing, and—later—television appearances. Together, they built a company structure that was as balanced as it was successful.
The Power Of Working Together
Working with a spouse can be challenging for some couples, but for Dan and Lori, it has always been a strength. Their dynamic is one of harmony, shared vision, and complementary talents. Lori has often said that Dan is the “numbers guy” while she’s the “creative inventor.” This division of labor has been key to their growth.
The two even share a desk in their Chicago office—a symbolic and literal representation of how closely they collaborate. Dan’s behind-the-scenes stability has helped ground the business, especially during periods of rapid expansion and media attention.
Patenting Over 100 Products Together
One of the most impressive feats of Dan and Lori’s partnership is the sheer volume of successful products they’ve developed. Together, they’ve patented more than 100 unique items, many of which have been featured on QVC and other major retail platforms.
These products include clever organizers, cosmetic storage units, and home essentials—all designed to solve everyday problems. Lori may be the face of the brand, but Dan has been a crucial force behind its design, logistics, and distribution. Each patent is a reflection of their shared process and mutual dedication to innovation.
Dan’s Role During Shark Tank Fame
When Lori joined the cast of Shark Tank in 2012, her public profile skyrocketed. While she became known nationwide as the “Queen of QVC” and a no-nonsense investor, Dan stayed behind the curtain—quietly making sure the business could keep up with the demands of fame.
With Lori investing in companies like Scrub Daddy, Squatty Potty, and more, Dan focused on internal operations. He managed finances, ensured smooth production timelines, and provided the stability that allowed Lori to thrive in the spotlight. He has never tried to compete with her visibility, content to be the person who ensures everything works behind the scenes.
A Private Life Anchored In Partnership
Despite their high-profile business success, Dan and Lori have kept their personal life low-key. They don’t seek out red carpet events or splashy magazine covers. Instead, they prioritize privacy and focus on what matters most—each other and the work they love.
In her 2014 book Invent It, Sell It, Bank It!, Lori dedicated a heartfelt message to Dan. She wrote, “You stood by me, loved me, and made me believe in myself. You have changed my life profoundly. I will love you forever.” That sentiment sums up the essence of their relationship—built on trust, belief, and unwavering support.
Building A Business That Works Around Their Lives
Lori has openly talked about how entrepreneurship is not a 9-to-5 job. In interviews, she has described it as a 24/7 commitment, where weekends, holidays, and late nights are often filled with work. Dan has been with her through all of it.
Their ability to integrate their professional lives with their personal relationship is part of what makes their story so unique. They have designed a business that fits who they are—not the other way around. This flexibility and unity are rare, and they’ve made it work for more than two decades.
