Lincoln "Bendy" Stephens discovered his calling through his own mental battlefield. After serving in the military and navigating the challenges of PTSD and neurodivergence, he found that golf became more than a game—it became his laboratory for understanding how the mind works under pressure.
What started as personal healing evolved into a mission to help other golfers break through their mental barriers. Lincoln combines his military background with deep study of sports psychology, drawing from proven frameworks by Dr. Bob Rotella, Dr. Raymond Prior, and Karl Morris. His neurodivergent perspective allows him to spot cognitive patterns that others miss, making him uniquely skilled at decoding how each player's mind operates in high-pressure situations.
Lincoln's coaching philosophy centers on building what he calls "mental armor"—the psychological resilience that allows players to perform their best when it matters most. He integrates traditional technical coaching with military stress inoculation techniques, applied sports psychology, and biometric feedback to create a comprehensive training system.
His method isn't about positive thinking or quick fixes. It's about rewiring the brain's response to pressure through structured, practical work that creates lasting change. Players learn to transform mental noise into focused energy, turning their biggest psychological challenges into competitive advantages.
Lincoln works almost exclusively with committed amateur golfers and single-figure handicappers who know they have more to give. His ideal clients are players who:
• Perform well in practice but struggle in competition
• Want to move beyond "just relax" advice to real mental training
• Are ready to invest in the psychological side of their game with the same intensity they bring to their swing
Whether you're trying to break through a scoring plateau or seeking the mental edge that separates good players from great ones, Lincoln helps serious golfers train their minds like elite athletes.
Because he's walked the path from mental chaos to breakthrough performance, Lincoln understands what it takes to build a game that thrives under pressure—not just survives it.

Book Now"I used to fall apart on the back nine when I had a good score going. Lincoln helped me understand that my brain was hijacking my swing. Now I have routines that keep me steady when the pressure's on. Shot my best round ever last month—68 with people watching."
"The mental side was always my weakness. I'd hit it pure on the range then spray it everywhere in competition. Lincoln showed me how to train my focus like I was training my swing. The difference in my tournament play has been massive."
"What clicked for me was when Lincoln explained how my military background was actually working against me on the course—too much tension, too much control. He taught me to harness that discipline without strangling my swing. I'm playing the best golf of my life."
"I've always been a head case under pressure. Lincoln didn't just tell me to relax—he gave me actual tools to manage my nerves. The biometric feedback showed me exactly when I was getting tight. Now I catch it before it ruins my round."
"I was stuck in this loop of overthinking every shot. Lincoln helped me build a pre-shot routine that actually works when my heart's pounding. It's like having a mental reset button. My bad rounds aren't disasters anymore."
"The breakthrough came when Lincoln helped me see that my ADHD wasn't a handicap—it was an advantage if I channeled it right. He taught me to use my rapid-fire thinking to read the course better. I'm seeing shots I never saw before."
"I thought I just needed to fix my swing. Turns out my swing was fine—it was the war going on in my head that was the problem. Lincoln helped me quiet the noise and trust what I'd trained. My confidence has never been higher."
"After struggling with depression, golf was one of the few things that brought me joy. But then the pressure to perform started killing that joy. Lincoln helped me remember why I love this game while still competing at a high level. Game-changer."
"I'm a perfectionist which was destroying my course management. Lincoln taught me that sometimes good enough is perfect. My decision-making has improved massively and I'm taking way fewer big numbers."
"I've been playing off single figures for years but always felt like I was fighting myself out there. Lincoln showed me how to get out of my own way. The game feels easier now, more natural. I'm actually enjoying pressure situations."
