Tell the Dear Fathers community more about who you are and what you do?
I’m Kelin Mark Sr.—a father, educator, author, and speaker who has spent more than two decades working with students and families. Throughout my career, I’ve had the honor of becoming the first Black male principal at two different schools, experiences that deepened my understanding of leadership, representation, and the importance of creating environments where every child and family feels seen and valued.
Every day I get a front-row seat to what helps children succeed and what causes them to struggle. Over the years, one thing has become incredibly clear: fathers matter.
That realization has shaped my life’s work. Through my consulting, speaking, and writing, I help schools move beyond simply asking parents to attend events and instead build meaningful partnerships with families, with a special focus on intentionally engaging fathers. I believe dads aren’t a bonus in a child’s education—they’re an essential part of it.
What inspired you to create The Dad Difference Playbook?
The book was born from two worlds colliding—my work as a school leader and my experience as a father.
For years I watched schools struggle to engage fathers while dads often wanted to help but weren’t sure how. At the same time, I was navigating fatherhood myself, learning that showing up consistently matters more than being perfect.
I didn’t want to write another parenting book full of theory. I wanted to create something practical—a playbook filled with simple, actionable strategies fathers can use immediately to make a difference in their child’s life. Every dad deserves to know that small, intentional actions create lasting impact.
What does Dad’n Different mean to you?
To me, Dad’n Different means leading with intention instead of assumption.
It’s choosing presence over perfection.
It’s understanding that being a father isn’t simply providing financially—it’s providing emotionally, mentally, spiritually, and academically. It’s recognizing that your presence changes rooms, conversations, confidence, and futures.
Dad’n Different means refusing to settle for the bare minimum when your child deserves your very best.
Who is Kelin as a Black father?
Before anything else, I’m simply a dad who loves his son deeply.
I wanted my son to grow up knowing he was supported, challenged, and believed in. That meant being present—not just for the big moments but also for the ordinary ones. Practices, conversations in the car, difficult decisions, disappointments, celebrations—all of those moments matter.
As a Black father, I also understand that I have a responsibility to prepare him for opportunities and obstacles while reminding him that his identity is his strength, not something he has to apologize for. My goal has always been to raise a confident, compassionate young man who knows who he is before the world tries to tell him.
How did your experience as a father help create your playbook?
Every page has a piece of my own journey in it.
I didn’t write from the perspective of someone who has all the answers. I wrote as someone who has learned, adjusted, celebrated wins, and made mistakes.
Watching my son grow—from elementary school to becoming a college student-athlete—reminded me that fatherhood changes with every season. The conversations you have with a six-year-old aren’t the conversations you have with an eighteen-year-old. The playbook reflects that evolution while keeping one message constant: your child never outgrows your influence.
How has your work in schools given you a different perspective on raising kids?
Working in schools has shown me something many people don’t get to see.
I’ve watched thousands of students walk through school doors every morning, and over time patterns become impossible to ignore. When fathers are engaged, students often show greater confidence, stronger attendance, better behavior, and higher levels of perseverance.
I’ve also learned that schools sometimes unintentionally communicate primarily with moms, leaving fathers feeling like spectators instead of partners.
That’s why I challenge both schools and dads. Schools have to intentionally invite fathers in, and fathers have to intentionally step in. The responsibility belongs to both.
Any advice to dads raising student-athletes?
Don’t let the sport become bigger than the child.
Too many conversations revolve around points scored, scholarships, rankings, and playing time. Your child also needs someone asking how they’re doing emotionally, academically, and mentally.
Teach them discipline, humility, resilience, and character because those are the qualities that last long after the final game. Celebrate effort as much as outcomes, and remind them that who they become will always matter more than what they accomplish.
When fathers are intentionally engaged, how does that shape children’s development?
Intentional father engagement builds confidence, security, resilience, and identity.
Children who know someone consistently believes in them approach challenges differently. They recover from setbacks differently. They see themselves differently.
A father’s presence communicates one powerful message: “You matter.”
That message influences how children perform in school, build relationships, solve problems, and eventually parent the next generation. Presence today creates legacy tomorrow.
What are three takeaways you want people to get from The Dad Difference Playbook?
First, your presence is powerful. You don’t have to be perfect—you just have to be present.
Second, small, consistent actions beat occasional grand gestures. The everyday moments shape children far more than the highlight reel.
Third, your influence extends far beyond graduation. You’re not just helping your child succeed in school—you’re helping shape the adult they’ll become.
What does legacy mean to you?
Legacy isn’t what people say about you after you’re gone.
Legacy is what continues because you were here.
For me, it’s raising a son who loves people well, serves others, and lives with integrity. It’s helping fathers realize how valuable they are. And it’s changing how schools engage families so more children experience the benefits of having an involved dad.
If my work inspires one father to become more intentional with his child, that legacy keeps growing long after I’m gone.
What’s next for you and how can people follow you and purchase your playbook?
I’m expanding The Dad Difference into school partnerships, workshops, keynote presentations, and a national movement that equips fathers with practical tools to become stronger partners in their children’s education.
I’m also growing the 5,000 Fathers Challenge, encouraging dads across the country to make one intentional play each week because lasting change happens through consistent action.
