What this means

Our Coaches and Staff



Aaron grew up in the Vancouver area and started CrossFit in 2018 with the Hero Benchmark Murph as his first WOD, which hooked him instantly. He then moved to Calgary in 2019 and joined CFC. After a few years of membership, he started his coaching mentorship under Brett and began the next stage of his CrossFit Journey.



More About Aaron

Aaron will be the first to say that you don't need to be "fit enough" to come in and try CrossFit. He routinely recounts the fact that he had zero athletic background or sports experience when he walked into his first box and that CrossFit communities are incredibly welcoming and the workouts are infinitely scalable, that is we scale to meet you where you are - we don't change the programs, so everyone can do every workout.



Ari is a lifelong athlete, growing up a competitive gymnast before transitioning to cheerleading in university. She spent six years coaching competitive gymnastics before switching her focus to group fitness and CrossFit in 2021.

Conrad Tang


DCM, Msc, L.Ac

Conrad graduated from the Canadian Memorial Chiropractic College, then continued on to complete a Master’s of Science degree specializing in biomechanics at the University of Calgary Human Performance Lab. He also received a certification to perform contemporary medical acupuncture from McMaster University, and is a Kinesiology graduate specializing in exercise physiology from the University of Calgary.


More About Conrad

Conrad strongly believes in an evidence-based and informed approach to patient-centered care. He also recognizes that the human body is a complex system, which requires an individualized approach. A properly done patient assessment not only incorporates orthopedic or functional tests, but the observation of human movement, such as the full squat, in order to assess the patient’s joint range of motion, coordination, and balance, among other things. Additionally, he believes that an accurate diagnosis is vital, in order to specify the treatment for optimal results and progress. Once the information from the assessment is gathered, the area of concern has been identified, the therapeutic interventions can then be applied. These therapeutic tools may include soft tissue work such as FR© (Functional Range Release), acupuncture or dry needling, joint mobilizations or manipulations, therapeutic taping, which all facilitate the conditions of exercise, in order to optimize the adaptation to promote healthy change.

To compliment his practice, he teaches movement classes as a FRC© (Functional Range Conditioning) mobility specialist, which is a comprehensive joint training system based on scientific principles and research. The three main training goals of these classes include mobility development or the active usable motion that one possesses, joint strength, and body control.

Conrad’s goals are simple – he encourages the active collaboration of the decision-making process with patients, enjoys sharing his knowledge of health with others, and wants to help people get better. His past experience includes working with Track & Field Canadian Nationals, Bobsled Canada Skeleton, USA Skeleton, Professional dancers, Professional MMA fighters, Calgary Minor Hockey, Okotoks Jr. A Lacrosse, and CrossFit athletes.

Coach Mentorship Program

There are few gyms with more coaching experience than CrossFit Calgary.

Owner Brett Marshall completed his first CrossFit L1 course in 2006, CrossFit Calgary became an official affiliate later that year, and Brett became a member of the CrossFit HQ L1 Training Staff in 2010.

To ensure the highest quality coaching experience for our members, CrossFit Calgary has developed an intensive mentorship program which may take 3 years or longer to complete. To succeed, coaching candidates must have a strong commitment to learning, volunteering, and becoming part of the CrossFit Calgary community.

Prerequisites for the program include a L1 CrossFit course, one year membership at CFC, and a successful interview with coach Brett.

Phase 1: 50 hours of coach shadowing within a 6-month span, including shadowing in kids, teens, and specialized programs; and a thorough observation of the fundamental movements from a coaching perspective, followed by a formal review meeting.

Phase 2: 50 hours of shadowing as a “mentoring coach” within a 6-month span, as a CFC co-coach, a support role to the CFC lead coach. The mentoring coach and lead coach both take notes so that professional development can be compared, guided, and evaluated.

Phase 3: In a series of meetings, coach Brett reviews coaching effectiveness based on the ability to recognize faults in movement and then be able to effectively cue members towards improvement.

Upon successful completion of these meetings, a candidate may be offered a probationary contract with CrossFit Calgary to continue their professional development while working as a CrossFit Calgary co-coach.

It is the responsibility of the co-coach to then gain competence in the lead coach role, by gradually taking over all components of class instruction.

CrossFit Calgary coaches are then supported in their professional development through four levels of coaching designation after the mentorship process. The coaching designations are Coach L1, Coach L2, Coach L3 and finally Head Coach.

For more information regarding coaching designations and opportunities, please contact admin@crossfitcalgary.ca.

“ My coaches (Laura, Erin, Michelle and Brett) worked with me to make sure I understood the mechanics of each movement and how they could be scaled for me. Their interest in my personal improvement was overwhelming and something I’m thankful for every day. ”
