We are M3 Golf Lab


The M3 Performance LAB is a cutting-edge, progressive paradigm for Game Improvement and Golf Performance developed by Luke Brosterhous MS, PGA, founder of Luke Brosterhous Golf, in collaboration with Finn Gerstell PT, DPT, OCS, FAAOMPT, owner of Four Points Physical Therapy. 

The M3 Performance LAB combines Titleist Performance Institute (TPI), Trackman 4 Launch Monitor, 3-D Motion Analysis (K-Motion & Hackmotion), and Mindset Training under one roof.

Our ultimate goal is to offer a new paradigm for Golf Instruction and Performance Coaching through a unique 360 approach focused on motion, mechanics, and mindset. Backed by credentialed, award-winning expertise and data-driven, state-of-the-art technology, the M3 model offers golfers a structure and environment to achieve long-term improvement and performance gain


Mechanics depend on motion. We get your motion right, and mechanics follow. At the M3 Golf LAB, we prioritize motion, then mechanics. Once you have sound structure, we can then add speed. From there, practicing the right way is the most efficient way to long term improvement and success, using data driven, researched methods of improvement. We aren’t a band-aid, we are a state of the art method for long-term improvement

Tatiana McCalla

Tatiana was introduced to teaching golf during her college golf days when she helped teach golf clinics and junior golf during summer golf jobs at various country clubs. This was when she developed her passion for helping others learn, improve, and enjoy the game of golf.

Tatiana was on her way to the Cactus Tour in Scottsdale, AZ, but then suffered a shoulder injury and decided to shift careers. She fell in love with the game of golf when she played for her high school golf team in Dacula, Georgia, earning low medalist every year. Earning her 6th in her state. Tatiana played at the collegiate level in north Georgia on a full scholarship. She has also worked at multiple golf courses across Georgia and Colorado, including: Hamilton Mill Country Club, Athens Country Club, West Woods Golf Club, and River Valley Ranch to name a few.

Tatiana feels blessed to now enjoy a career where she gets to combine two things she passionate about, helping people and golf! Her philosophy as an instructor is to develop, inspire, motivate and support her students to realize their fullest potential.


Tom Taylor

After growing up in Oklahoma, playing college golf there as well as starting my PGA of America career, I landed in Steamboat Springs almost 30 years ago. I have been lucky enough to continue my career in Steamboat for a majority of that time.  I have always been intrigued by the golf swing and have spent countless hours working on my own swing.  Teaching has always been a passion of mine, allowing others to enjoy the game as much as I do. 

My teaching philosophy has always been a simple one in making sure the students are fundamentally sound in the basics of grip, stance, and alignment.  Teaching the basics of rotation and good impact as well.  A few years ago, I was having difficulty with my impact and losing distance.  I went to see Luke Brosterhous for help.  With the help of TPI (Titleist Performance Institute) we were able to determine my weaknesses with screening and with exercise and practice, my ball striking improved greatly. What an eye opener to a more efficient way to instruct. 

Currently I am in the process of establishing my own certification of TPI and becoming a more technical instructor while keeping my simple approach to the game.  Along with teaching I have become a Ping Certified Fitter along with other fit systems.
