Leadership Spotlight: TNLA Chairman Devin D. Guinn

​My journey into the green industry and TNLA was shaped less by a master plan than by people, opportunity, and timing. Like many in this profession, I started by focusing on the work in front of me: learning the craft, showing up consistently, and doing my best to build something meaningful. Over time, that work evolved into a deeper sense of purpose not just building landscapes, but helping build an industry rooted in respect, relationships, and long‑term stewardship

I became involved with TNLA because I saw the value of connection. This industry is built on experience passed from one person to another, and I quickly learned that being part of a professional community matters. TNLA offered a place to learn from others, to contribute ideas, and to grow alongside people who care deeply about raising the standard of our work. It wasn’t just about resources it was about belonging to something bigger than myself.

​Along the way, I’ve been fortunate to learn from mentors, colleagues, and peers who took the time to invest in me. Some offered guidance during pivotal moments, others led simply by example. Their influence reminded me that leadership is not about having all the answers—it’s about being willing to listen, learn, and step forward when needed. Those lessons continue to shape how I approach leadership today.

For me, leadership is rooted in service. It’s about showing up with integrity, being accountable to others, and making space for different perspectives. Belonging means knowing that your presence matters and that your voice has value. As we recognize Black History Month, I’m especially mindful of that truth. Being the first African American Chair of TNLA is an honor I carry with humility and gratitude. It represents progress, but it also reflects the many individuals—past and present—whose perseverance, contributions, and leadership helped make that moment possible.

Black history is not separate from our industry’s story; it is part of it. It reminds us of the importance of access, opportunity, and representation, and of the responsibility we have to ensure that leadership reflects the diversity of talent within our profession. I hope my role encourages others to see themselves as leaders and contributors, regardless of background or starting point.

TNLA has played an important role in my professional growth, and membership has been key to that experience. The relationships formed through this organization have strengthened my perspective and reinforced the value of collaboration. When we invest in one another—through mentorship, education, and shared accountability—we strengthen the future of the industry as a whole.

Looking ahead, I believe our greatest strength lies in our people. By honoring the foundation that built this industry while welcoming new voices and ideas, we create space for innovation and continuity. My goal as Chair is to help foster an environment where professionalism, respect, and belonging are not just ideals, but everyday practice.
​
I’m grateful for the opportunity to serve TNLA, thankful for those who came before me, and hopeful for what we can continue to build together—grounded in history, strengthened by community, and focused on a future that includes us all.
