The Power of a Limitless Mindset
Every great leader begins with a defining belief. For Derrick Grissom, MBA, that belief is simple yet profound: “Your potential is truly limitless.” Those words are not just a mantra but a reflection of a life dedicated to growth, resilience, and purpose.
Today, Derrick stands as a dynamic Executive Fiber Specialist at AT&T, an accomplished author, motivational speaker, and founder of My Limitless Growth, LLC. His journey bridges two worlds — the corporate boardroom and the motivational stage — where his mission remains unwavering: to help individuals and organizations unlock the full spectrum of their potential.
Foundation: The Early Roots of Drive and Discipline
Derrick’s foundation in leadership and business was built on the value of hard work and education. A native of Atlanta, Georgia, he earned his bachelor’s degree in Business Administration from Oglethorpe University before pursuing an accelerated MBA at South University. His academic success laid the groundwork for a thriving career in sales and executive leadership, where he quickly became known for his strategic insight and ability to inspire teams.
But it wasn’t just academic ambition that propelled him forward. It was a genuine curiosity for people — understanding their challenges, connecting with their motivations, and empowering them to see beyond perceived limits. That curiosity soon evolved into a calling.
Ascent: A Career Built on Vision and Momentum
Over 13 years in the telecommunications industry, Derrick has established himself as a trusted expert in Business Fiber and VOIP technology. At AT&T, where he currently serves as Executive Fiber Specialist, Derrick helps small and mid-market businesses embrace the transformative power of connectivity. His consultative approach goes beyond selling services; he’s driven to show companies how innovation can redefine their future.
Within just one year at AT&T, Derrick’s leadership has already been recognized. He was selected by senior leadership to participate in the AT&T Mid-Market Sales Virtual Mentorship Program (VMP), a national initiative designed to cultivate the next generation of sales leaders. In his words, “Whatever you do, try to keep a positive and limitless mindset while pursuing your goals — it’ll directly affect the outcome.” That mindset is precisely what has guided him through every career transition.
Before joining AT&T, Derrick held leadership roles at companies including Accenture, Clearwave Fiber, Hargray Communications, and Comcast Business. From closing multimillion-dollar contracts to leading high-performing teams to President’s Club recognition, Derrick consistently demonstrated a rare blend of strategic acumen and motivational leadership. His ability to generate growth — both in revenue and in people — became his professional signature.
Impact: Leading Beyond Boundaries
Derrick’s impact stretches far beyond sales performance. Through My Limitless Growth, LLC, he channels his passion for speaking, mentoring, and authorship into initiatives that inspire transformation. In 2023, he published three books — Limitless, 6 Steps to Limitless Sales Success, and Your Real Life — each a reflection of his belief that success begins with mindset.
That same year, Derrick’s work gained national attention when he was featured at the Los Angeles Times Festival of Books and later recognized at the Annual Essence Festival in New Orleans. His books have sold over 1,000 copies both online and in person, sparking conversations about leadership, self-belief, and resilience.
Through his Limitless Podcast, Derrick interviews changemakers who embody the same principles of drive and authenticity that define his own story. Whether speaking to corporate audiences, youth groups, or fellow entrepreneurs, Derrick’s voice resonates with sincerity and strength. His favorite moments often come when he’s mentoring young people. As he shared in a recent post, “In addition to my corporate day job, I absolutely love motivating our youth as well.”
Leadership and Community Engagement
A recognized community leader, Derrick serves on several chamber and nonprofit boards across metro Atlanta, where he helps shape initiatives that drive economic growth and social progress. His commitment to leadership development also shines through his involvement with Toastmasters International, where he earned the organization’s highest speaking honor — the Distinguished Toastmaster (DTM) title.
Within the National Speakers Association (NSA) Georgia Chapter, Derrick serves as the Director of Culture, ensuring that every voice is heard and valued. His dedication to diversity and inclusion extends back to his corporate days, where he helped grow OUT-ERG, an employee resource group that expanded from one member to more than 1,500 LGBT and allied participants.
Vision for the Future: The Limitless Path Ahead
Derrick’s vision continues to evolve, grounded in purpose and fueled by his belief that every experience adds another layer to personal growth. Whether in a client meeting at AT&T, a youth empowerment event, or behind the microphone on his podcast, Derrick’s mission remains consistent — to encourage others to embrace a mindset without boundaries.
He often reminds audiences that growth is not a destination but a journey. With his combination of corporate expertise, entrepreneurial spirit, and motivational leadership, Derrick Grissom embodies what it means to live “limitlessly.”
