Meet the Minds That Made Personality the Key to Golf Performance
John & Sevan Weir pioneered Mental Golf Typeâ˘âthe first system to show how personality and stress interact to predict outcomes, unlock flow, and train the mind with precision.
Their discovery turned proven psychology into practical tools trusted by serious golfers, coaches, and teams worldwide.
â¤ď¸ 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 werenât interested in generic adviceâwe 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 whatâs 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 forâmental performance backed by results.
âGreat coaching begins with knowing yourselfâand helping others rise when it matters most."
The Team That Turned Personality Into a Performance Breakthrough
Discover John and Sevanâs personal journeysâand how they built Mental Golf Type into a global coaching movement.

John Weir
Founder of Mental Golf TypeÂŽ | Author of The Golferâs Guide to Mental Fitness
John Weir is a globally respected mental performance coach and the creator of Mental Golf TypeÂŽâa 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.
Johnâs mental coaching strategies are grounded in both science and lived experience. He is the author of The Golferâs Guide to Mental Fitness and has caddied on some of golfâs 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 Typeâthe 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.

âThis isnât just performance trainingâitâs personal growth through the game.âÂ
Together, John and Sevan fused their unique strengthsâperformance coaching and personality typologyâto 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, itâs time to share the story behind how Mental Golf Type was born.
đ§ The Mental Golf TypeÂŽ Development Story
How Personality Became the Missing Link in Golfâs 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.
âł Where It All Started: A Mental Game That Didnât Work for Everyone
For years, golfers were given the same generic advice to master the mental game:
âJust stay confident.â
âFocus harder.â
âBe more positive.â
But for many playersâespecially under pressureâthose tips didnât help. They lost their feel. Their tempo vanished. The harder they tried, the more it slipped.
Thatâs when we realized: something was missing.
đ§Ź The Insight That Changed Everything: Personality Was the Missing Link
It wasnât 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 hereâs where Mental Golf TypeÂŽÂ cracked the code:
We didnât just describe personalityâwe 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 stressâand what to do about it.

đĄThe Discovery: Stress Triggers Mental Shifts That Sabotage Performance
What we found was groundbreaking:
Every golfer operates with a dominant set of mental functionsâtheir unique Mental Golf Type.
But under even subtle stress, those functions begin to shift.
At first, itâs nearly undetectableâan inner tension, a creeping doubt, a sense of things not clicking.
But soon, thereâs a breakdown in clarity, tempo, emotional regulation, and even physical movement.
The core insight:
Performance loss isnât random. Itâs quite predictableâand personality shows you where, why, and how it happens.
This wasnât just about mindset.
We began connecting these shifts to motor function breakdowns, emotional patterns, and decision-making under fire.
We didnât just coach players.
We observed how they processed pressureâand thatâs where everything changed.

đ§Â 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 playerâs personality.
We identified how each Mental Golf Type:
-
Gathers and evaluates information on the course
-
Builds confidence or erodes it
-
Rallies after a mistakeâor 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 importantlyâwe could help them reset and return to their optimal performance stateâbefore the next shot, not after the round
Thatâs when Mental Golf Type became more than a framework.
It became a practical system.
đď¸ââď¸Â What Makes Mental Golf Type⢠Different
Mental Golf Type isnât about labeling players. Itâs 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 donât stop at awareness. We show players how to train, prepare, compete, and recoverâin ways that align with how their brain naturally operates.
And when stress throws them off track, we give them the tools to reset and recoverâfast.
Thatâs the MGT edge.
