Amanda Mandi Martin remains the steady force behind Martin Bros Customs. Explore her journey, family life with Joe, and dedication to dog rescue after seven seasons of Iron Resurrection.
Amanda “Mandi” Martin may not spend her days behind a welding torch like her husband Joe, but she has been just as essential to the success of Martin Bros Customs. As the shop’s business manager, co-owner, and one of the familiar faces of Iron Resurrection, she helped transform the Texas-based business into one of the best-known custom automotive shops in the country. Today, in 2026, Mandi continues to play that role while embracing a more independent chapter alongside Joe following the end of the hit MotorTrend series.
While Joe Martin is often celebrated for his extraordinary fabrication skills and creative vision, Mandi has quietly kept the business running behind the scenes. With her sharp business mind, calm leadership, and deep love for both the automotive world and animals, she has played an essential role in shaping Martin Bros Customs into what it is today. Long after Iron Resurrection wrapped its seven-season run, she remains at the heart of both the family business and the loyal community that continues to follow their journey.
Born Amanda Jill Keathley on December 11, 1973, in Red Oak, Texas, Amanda “Mandi” Martin is 52 years old in 2026. She grew up with a practical, hardworking outlook shaped by small-town values. Before stepping fully into the custom car world alongside Joe, she built a successful career in banking and finance, eventually serving in management roles where she developed strong skills in organization, customer relations, and operations.
That experience proved invaluable when she joined Martin Bros Customs full time. Her ability to manage the books, oversee client relationships, and keep complex projects on schedule has allowed Joe to focus on what he does best—turning metal into art.
A True Partnership Built on Respect and Shared Vision
One of the most memorable aspects of Iron Resurrection was watching Joe and Mandi’s partnership unfold naturally on screen. Their chemistry never felt manufactured. Instead, viewers saw two people whose strengths complemented one another, each playing an equally important role in the success of the business.
During their candid June 2026 YouTube interview, the couple reflected on how they met and learned to combine those strengths. Joe spoke about the early challenges of balancing the demands of a busy custom shop with family life, while Mandi described the satisfaction of seeing a project come together—from the initial vehicle search to handing the keys to a delighted customer.
Behind the scenes, Mandi’s responsibilities stretched far beyond what viewers saw on television. She managed the day-to-day operations, helped coordinate parts hunts with Shag, and brought a calm, practical approach to the inevitable challenges of running a busy custom shop. Her contributions were never the loudest, but they were among the most important. Fans have often commented on her composed demeanor and her ability to keep everything moving forward, whether she was solving a complicated logistics issue or encouraging the crew through long days in the shop.
After seven successful seasons on MotorTrend, Joe and Mandi made the thoughtful decision to step away from traditional network television. In their July 2025 Instagram announcement, they shared that they had wrapped up their time with the network and were moving forward independently. The change gave them the freedom to create content on their own terms, including longer build videos, honest shop updates, and more personal glimpses into everyday life at Martin Bros Customs in Johnson City, Texas. For Mandi, it also created more opportunities to connect directly with the community that has supported them for years.
Life After Iron Resurrection: Freedom and Authenticity
Stepping away from network television has allowed Mandi to embrace a more balanced pace while remaining deeply involved in the business. On the couple’s YouTube channel, she regularly appears alongside Joe in shop updates, event coverage, and candid conversations about everything from current builds to the lessons they’ve learned over the years.
Their 2026 interview offered an even closer look at that transition. Mandi spoke openly about the rewards and challenges of building a business together, the experiences they gained during their television years, and the excitement of having complete control over how they now share their work. There’s a noticeable sense of renewed energy throughout their recent content, with no production schedules dictating when a project has to be “camera ready.”
Martin Bros Customs remains as active as ever in Johnson City. Recent projects featured across their platforms include refined Nova builds, Foxbody developments, and custom components that combine modern technology with traditional craftsmanship. While Joe continues leading the fabrication work, Mandi remains at the heart of the operation, keeping day-to-day business running smoothly while also enjoying the creative side of each project.
Mandi’s Passion for Dogs and Animal Rescue
Away from the noise of grinders and welding torches, Mandi has an unmistakable soft spot for animals, especially dogs. On her personal Instagram (@mrs.martinbroscustoms), she often shares quieter, more intimate glimpses of life beyond the shop. Whether she’s driving a tractor around their property with a big smile, tackling home improvement projects that bring her a sense of calm and accomplishment, or simply spending time with the dogs, these posts reveal a woman who finds joy in both hard work and simple pleasures.
Her love for rescue dogs shines through especially brightly. Mandi has become a dedicated advocate for pit bulls and other animals in need, regularly posting about foster dogs, successful adoptions, and the organizations she supports. Over the years, she and Joe have fostered multiple dogs, offering them temporary love and stability. In one especially touching update, she shared the story of Miss Maggie, a dog the family fostered in 2023. After the original owner faced health challenges, Mandi helped ensure Maggie found a loving permanent home.
Many of her posts highlight the comfort and balance her animals bring after long days at the shop. One moment she might be coordinating parts orders or reviewing build timelines; the next, she’s celebrating a new adoption or enjoying a peaceful afternoon project at home. For Mandi, caring for rescue dogs is far more than a hobby — it’s a meaningful part of who she is. That same steady compassion and care she shows her four-legged family members is the same warmth and support she brings to Martin Bros Customs every single day.
These authentic slices of everyday life have endeared her even more to fans, showing that behind the successful businesswoman and shop co-owner is someone who deeply values balance, family, and the small joys that make life meaningful.
The Quiet Strength Behind the Builds
What continues to stand out about Mandi Martin is her steady presence. While Joe’s fabrication skills naturally draw much of the spotlight, Mandi’s contributions—both practical and personal—help create the environment where great work can happen. She brings organization, warmth, and a grounded perspective that balances the fast-paced, demanding world of custom car building.
Her love for dogs adds another layer to her public persona. Whether she’s sharing an update about a foster dog, celebrating a successful adoption, or simply posting a photo of the family’s pets, Mandi reminds fans that life at Martin Bros Customs extends well beyond the shop floor. Those moments of compassion and everyday life resonate with followers who appreciate seeing the people behind the builds just as much as the finished vehicles themselves.
Looking back on their Iron Resurrection years, Mandi has always focused less on television fame and more on the relationships and experiences the journey created. That same authenticity continues to define everything she and Joe share today, giving longtime fans an even more personal look at the business and the life they’ve built together.
