I don’t believe in a one-size-fits-all golf swing.

Every golfer is different, which is why I take a personalized approach to instruction. I work with you to understand your goals, physical capabilities, and how you learn best. From there, we build a plan that’s realistic, effective, and tailored specifically to you.

My coaching blends technical instruction with course management and the mental side of the game, because real improvement comes from putting all the pieces together.

I’m Isabella Portokalis, a PGA of Canada Golf Professional based in London, Ontario, and currently an Assistant Golf Professional at Sunningdale Golf & Country Club.

Golf has taken me far beyond where I started, shaping me as both a player and a coach. I competed at an elite level throughout my junior, amateur, and NCAA Division I career, representing Team Ontario and earning individual regional and provincial titles along the way. My competitive journey continued in the United States at Florida Gulf Coast University and Towson University, where I played against top talent across North America.

Competing at that level required more than just technical skill—it demanded discipline, mental toughness, and the ability to perform under pressure. I developed a deep understanding of course management, consistency, and what it truly takes to improve and compete.

Now, I bring that same high-performance mindset into my coaching. I’m passionate about helping golfers of all levels access the same principles, strategies, and insights that shaped my career, so they can play with more confidence, clarity, and purpose.

About Me

Who I Work With

Beginners

If you’re new to the game, I’ll help you build a strong foundation from the start. We’ll focus on fundamentals, developing consistent contact, and getting you comfortable on the course. My goal is to make golf feel approachable, enjoyable, and something you’re excited to keep coming back to.

Intermediate Players

If you’ve been playing for a while and want to take the next step, we’ll refine your swing, improve consistency, and focus on lowering your scores. This often includes dialing in your short game, improving course management, and identifying the areas that will have the biggest impact on your overall performance.

Advanced Golfers

If you’re playing competitively or working toward that level, I’ll help you elevate every part of your game. We’ll focus on advanced swing mechanics, strategic decision-making, and building the mental resilience needed to perform under pressure. My goal is to help you play with confidence, consistency, and a clear plan when it matters most.

What We’ll Work On

Short Game & Scoring
Lowering your score often comes down to what happens around the green. We’ll work on chipping, pitching, bunker play, and putting to help you save strokes and feel more confident in scoring situations.
Course Management & Strategy
Playing better golf isn’t just about hitting better shots—it’s about making smarter decisions. I’ll help you understand how to manage the course, choose the right targets, and play to your strengths.
Mental Performance & Confidence
Golf is as much mental as it is physical. We’ll work on building confidence, staying focused, and developing routines that help you perform consistently—especially under pressure.
Long-Term Game Improvement
Together, we’ll create a clear path for your development. Whether your goal is to break 100, 90, or compete at a higher level, we’ll focus on the areas that will move you forward and track your progress over time.
