I know how frustrating it can be when you play poorly. You have the equipment, you've put in the hours of practice, but you're still struggling. If this sounds familiar it's probably because your body is holding you back. 

If you can relate, than you have come to the right place. Hi, I'm Daniel Marinello, owner of Seattle Golf Fitness, which I opened to help golfers like you to hit further, be more consistent, avoid fatigue, and play pain free. 


I am a Titleist Performance Institute Level 3 Golf Fitness Trainer, a TPI Power Coach, and a National Academy of Sports Medicine Certified Personal Trainer. I have worked with hundreds of people with everyone from beginners to a two time PGA Tour Champion. I look forward to helping you achieve your golf and fitness goals.

I was born and raised on the Eastside. I was lucky enough to have a patient dad and grandpa who taught me how to play golf when I was in elementary school. Golf has always been a major part of our family and I think that is what sparked my enthusiasm to become a golf fitness trainer. I started my work as a personal trainer during my senior year of high school. Fitness was always a major passion of mine and sharing that passion with others did not feel like work to me. Over the following five years I helped clients lose fat, gain muscle and better their health. A few years ago I stumbled upon a Rory McIlroy workout video. Little did I know but Rory was addicted to weightlifting and is a beast in the gym. This got me thinking about fitness training for golf.


I began researching golf related training programs and learned about the Titleist Performance Institute (TPI), which is the gold standard for golf oriented training for medical professionals, fitness professionals and golf instructors. I saw that of the top 200 players in the world, 195 had a TPI certified member on their team. I realized that participating in TPI training was clearly the best way to learn about golf fitness training. My level 1 TPI course was life changing. The instructors were first class and I left wanting to dedicate all my time to golf fitness training. I then immediately started my level 2 course, where I received advanced training on golf fitness programming, progressions and nutrition. By the completion of this course I was all in, and I started my business, Seattle Golf Fitness.


Through Seattle Golf Fitness, I help clients improve their golf by improving their bodies. Through understanding how your specific body works, I can help you to improve your weaknesses, capitalize on your strengths, and find your most effective swing. Everyone’s swing is different and there is no “correct” swing. Many golf instructors will record your swing on video and then compare your swing to Tiger’s or Jordan’s, but this is unfair to you as less than 1% of golfers have the physical abilities to get into the same positions as the pros. My job as a golf personal trainer is to not to ensure you can replicate Tiger’s swing. Instead, it is to help you develop the most efficient swing that your body can produce.


To start, every new client is taken through a golf fitness evaluation where I will have a chance to test your mobility, stability, cardio and strength. From your results, I can pinpoint exactly what areas of your body are holding you back as a golfer. Next, I take these results and will generate a training plan specifically formulated to help you improve these areas. We then will work together to execute this plan, which will help you to have a better, more consistent swing, less pain, and lower scores.
