❤️ The Heart Behind Mental Golf Type

Mental Golf Type began with a shared mission: to help golfers break through the mental barriers that keep them from playing to their potential. We weren’t interested in generic advice—we wanted to understand what actually works for each individual.

Over time, that mission evolved into a system grounded in personality, precision, and performance under pressure. But what’s always stayed the same is why we do it.

We were there not just as spectators, but as believers in what it means to coach with clarity, compete with integrity, and perform when it counts. Cheryl represents everything MGT stands for—mental performance backed by results.

“Great coaching begins with knowing yourself—and helping others rise when it matters most."

The Team That Turned Personality Into a Performance Breakthrough

Discover John and Sevan’s personal journeys—and how they built Mental Golf Type into a global coaching movement.

John Weir

Founder of Mental Golf Type® | Author of The Golfer’s Guide to Mental Fitness

John Weir is a globally respected mental performance coach and the creator of Mental Golf Type®—a revolutionary system that helps players understand their minds and train with purpose. With decades of experience in golf psychology, hypnosis, and performance coaching, he has worked with junior champions, college standouts, and PGA Tour professionals.

John’s mental coaching strategies are grounded in both science and lived experience. He is the author of The Golfer’s Guide to Mental Fitness and has caddied on some of golf’s biggest stages, including Q-Schools worldwide, a full season on the Korn Ferry Tour, a Top-10 finish at the Puerto Rico Open, and the 2023 U.S. Open at Los Angeles Country Club. These experiences fuel his ability to coach under real pressure and help others rise to their moment.

Through thousands of hours of player observation and live coaching, John uncovered a critical pattern: when stress sets in, players shift out of their natural personality-based functioning. This cognitive disruption leads to breakdowns in focus, decision-making, motor control, and confidence. That discovery became the foundation of Mental Golf Type—the first system to make performance predictable by aligning training with how the mind actually works under pressure.

John is also a sought-after speaker, podcast host, and educator, committed to helping players break through mental barriers and play their best golf from the inside out.

Her vision has helped shape Mental Golf Type into more than just a framework—it’s become a movement rooted in personalization, empowerment, and real-world performance.

 

“This isn’t just performance training—it’s personal growth through the game.” 

Together, John and Sevan fused their unique strengths—performance coaching and personality typology—to create a system that meets golfers where they are and helps them grow from the inside out. What began as an idea rooted in clarity and purpose has evolved into something far greater.

Now, it’s time to share the story behind how Mental Golf Type was born.

🧠 The Mental Golf Type® Development Story

How Personality Became the Missing Link in Golf’s Mental Game

John spoke at the Proponent Group Summit, pictured here with Sevan and coaching icon Mike Bender, where he previously served as a mental performance coach at Mike Bender Golf Academy.

⛳ Where It All Started: A Mental Game That Didn’t Work for Everyone

For years, golfers were given the same generic advice to master the mental game:
“Just stay confident.”
“Focus harder.”
“Be more positive.”

But for many players—especially under pressure—those tips didn’t help. They lost their feel. Their tempo vanished. The harder they tried, the more it slipped.

That’s when we realized: something was missing.

🧬 The Insight That Changed Everything: Personality Was the Missing Link

It wasn’t until we began looking through the lens of personality that the mental game started to make sense. Drawing from the foundational work of Carl Jung, we explored how people are wired to process information, make decisions, and manage their internal and external worlds.

But here’s where Mental Golf Type® cracked the code:

We didn’t just describe personality—we discovered how it actually works under pressure, during competition, and in real-time golf performance.

 We saw patterns that were invisible before. Patterns that showed exactly why players were breaking down under stress—and what to do about it.

💡The Discovery: Stress Triggers Mental Shifts That Sabotage Performance

What we found was groundbreaking:

Every golfer operates with a dominant set of mental functions—their unique Mental Golf Type.
But under even subtle stress, those functions begin to shift.

At first, it’s nearly undetectable—an inner tension, a creeping doubt, a sense of things not clicking.

But soon, there’s a breakdown in clarity, tempo, emotional regulation, and even physical movement.

The core insight:

Performance loss isn’t random. It’s quite predictable—and personality shows you where, why, and how it happens.

This wasn’t just about mindset.
We began connecting these shifts to motor function breakdowns, emotional patterns, and decision-making under fire.

We didn’t just coach players.
We observed how they processed pressure—and that’s where everything changed.

🧭 From the Course to the System: Mapping the Real Mental Game

Over years of live sessions, competitive testing, and high-stakes coaching across every level of the game, we began to map the inner experience of golf based on a player’s personality.

We identified how each Mental Golf Type:

  • Gathers and evaluates information on the course

  • Builds confidence or erodes it

  • Rallies after a mistake—or spirals

  • Interprets pressure situations

  • Responds to structure, feedback, routine, and flow

The results were staggering. We could predict how players would respond before they even teed it up.
More importantly—we could help them reset and return to their optimal performance state—before the next shot, not after the round

That’s when Mental Golf Type became more than a framework.
It became a practical system.

🏌️‍♂️ What Makes Mental Golf Type™ Different

Mental Golf Type isn’t about labeling players. It’s about unlocking their personal performance code.

Our system identifies your:

  • Mental energy flow (Extraversion vs. Introversion)

  • Information-processing style (Sensing vs. iNtuition)

  • Decision-making pattern (Thinking vs. Feeling)

  • Approach to time, structure, and adaptability (Judging vs. Perceiving)

But we don’t stop at awareness. We show players how to train, prepare, compete, and recover—in ways that align with how their brain naturally operates.

And when stress throws them off track, we give them the tools to reset and recover—fast.

That’s the MGT edge.
