Troy Boot – Coach & Teens Trainer


Coach Troy started CrossFitting in 2009. He loved it from day one!
He did Cindy and was so sore for a week! The programming just made sense to him.
The results were amazing. Being a trainer back in the late 80’s early 90’s,
he wanted to learn and be able to help people!

There’s so many CrossFit memories over the last 11 years for Troy:
1) Competing
2) Going to the CrossFit Games (watching)
3) Witnessing coaches & clients hit PRs – Hard work does pay off!

Favorite Workout: Any AMRAP’s
Favorite Lift :1 Rep Thruster

Troy loves seeing new clients in foundations training and working on movements to fix their forms/technique and feeling comfortable in the CFOK Box and loving it!

The best advice he can give a new CrossFitter is : Believe in the programming. It is not easy but keep showing up and results will happen…you will change! Physically and mentally for the better! Communicate with the coaches, don’t hesitate!
Just ask for any kind of help or guidance anytime.

Favorite Quote: Hard work pays off!

Madi Gorman – Coach & Barbell Club


Originally from the island, I spent my childhood outdoors, mountain biking and snowboarding. Once moved to Kelowna I walked into CrossFit Okanagan just like anyone else. Immediately, I realized I had found something special. CrossFit quickly impacted my life, and I dove in head first, wanting to experience all aspects of this new found fitness. Starting with new training habits, pushing into nutrition knowledge and finally coaching. My passion for coaching is driven by a love for seeing people overcome fear, conquer new challenges and strive for better. Having members express what CrossFit has done to them not only physically but also mentally, is an experience that never gets old to me. Focusing more on movements, I enjoy the art of technique. It’s empowering to teach people not only how to move their body in functional ways but to also fine tune for each individual needs. It has brought a sense of confidence within myself that I did not have when I started CrossFit in 2012. I am forever lucky to work with an amazing team of coaches.

You can catch me coaching Thursday & Friday evenings, Barbell Club and every Saturday!

Michelle Dumaine – Coach 


My journey with CrossFit started in 2015. At the time, I was teaching group fitness classes : step aerobics, TRX and boot camps but I needed a new challenge. The gymnastics side of crossFit drew me in instantly as I grew up as competitive gymnast and have been coaching gymnastics since I was 16. During the day, I am a Gr 7 teacher at Dr. Knox Middle school.
I love coaching CrossFit because no matter what your level, background, injuries or limitations are, you are part of a healthy community and you accomplish so many exciting things that you never even knew were possible! I love seeing the growth in skill, strength and confidence that quickly develops when new members join the CFOK team!

Liz Blackburn – Coach & RMT


Originally from Salmon Arm, I moved to Kelowna in 2007 to go to attend post secondary school. Throughout my life I have been an active person, participating in soccer, snowboarding, dirtbiking, hiking, etc. I attended the gym often but my results weren’t progressing as I hit a plateau and it was becoming too regular and boring. Having a desk job has caused me to always struggle with back pain and to influence my muscles to compensate incorrectly. CrossFit has benefited me incredibly by relieving the back pain and teaching the correct muscles to fire. Now every year when dirtbiking season begins, I can go right back out there and not feel the physical struggle that normally occurs when getting back into the sport.  My life has changed mentally, emotionally and physically.

Always wanting to try CrossFit, I didn’t finally take the plunge until Dec 2014. It barely took me finishing the two weeks of Foundations to know that I was hooked and only a few months later to know I had a desire to become a coach. I took the L1 CrossFit Course in July 2015 and L2 in Aug 2019. I have been since absorbing all the knowledge and experience I can acquire.  My biggest motivation is seeing someone progress and watching them achieve something they never thought they could do!

Since becoming a CrossFit Coach, I have always had a strong desire to learn how to correct muscle imbalances. I completed the Registered Massage Therapy program in 2019 and am using the extent of knowledge as an RMT to even further coach the client’s in the gym. Currently I am working out of CrossFit Okanagan during the week and Pro Motion on Friday and Saturdays. It amazes me every time I step into the gym to see the progress everyone has made and the welcoming vibe you get as you walk through the door.  I encourage everyone to give CrossFit a shot, no matter what your goal is, your age, or that you have never been to a gym before– there is something for everyone, come embrace the community, make new friends, get a little sweaty and come change your life forever!

You can catch me coaching at CFOK Tuesday & Friday mornings as well as some Sundays!

 Trisha Desrosiers – Coach


I fell in love with CrossFit in the spring of 2015 when I used a groupon to try it out for a month. After my first week of Foundations I felt empowered and was very happy with myself! I knew I was hooked when I kept continuously surprising myself.
Growing up in the lower mainland I was always playing street hockey or soccer, volleyball, track n’ field and snowboarding. I also enjoy hunting, camping, hiking and fishing (however I am still learning how to touch an actual fish) My husband has since introduced me to snowmobiling. Thanks to CrossFit I am able to boondock and move my sled around a lot easier, successfully making a figure 8 in the snow! I love coaching because I get to meet so many different and wonderful people. I get excited to watch people accomplish a movement or lift for the first time. Seeing the faces of athletes who lift a weight that they never imagined was possible and for them to realize just how strong they are, is the highlight of my day! I love to learn new ideas and techniques about different ways people move. I will always help when someone wants extra coaching on a specific movement to or needs a little extra nudge to stay motivated. Crossfit is unlike anything you could ever experience and until you come and try it you will never really know
just how amazing CrossFit is…

You can catch me coaching Wednesday & Thursday mornings!
