My name is Mary Kathryn (MK). I was born in the United States but grew up in Switzerland. My passion for fitness began with competitive soccer and later transitioned to CrossFit during the pandemic. I earned a Bachelor of Science degree in Kinesiology from McGill University in Montreal, Canada. I am a Certified Personal Trainer and hold a Level 1 CrossFit Coaching Certificate. In addition to coaching, I am currently pursuing a Doctor of Physical Therapy degree at Boston University. I believe that movement is medicine, and I love helping athletes of all backgrounds grow stronger—both physically and mentally—through exercise.
