Happy Birthday Sensei Mac!



Today, please join me in wishing Sensei Mackenzie Meyers a happy 18th birthday! 

We are proud of and grateful for her, and know that she is ready for amazing success in life!

She’s a KMMA Blackbelt Leader! 


Mackenzie has been my student since she was 4 years old.



She was a great student and earned her first Blackbelt at like 7 years old!

We used to call her “Big Mac” by the way. 🙂



She earned her Shodan, 1st Degree Blackbelt, at 8; and then took a break…


you may also notice little Sensei Winston (now 3rd degree), Sensei Ben (testing for his 4th degree in March), Shihan Diego (4th degree), teen Shihan Harley (now 5th degree) and younger Shihan Carolyn (now 4th degree) and Shihan Bond (testing for 5th degree in March) in the photo. 🙂


While Sensei Mac mentioned her 6 year break as a mistake and one of her greater regrets in her 2nd Degree speech a few years ago, she also taught a great lesson with her return.

   It’s never too late to come home again; and it’s never too late to start again on a dream.

Some live with regrets; others take actions to turn them into success stories, like Sensei Mackenzie did! 

She’s been back training now for over 5 years- not only growing as a martial artist, person and leader; but also helping us sow into the next generation of Blackbelt Leaders here too!


and, as she prepares for her next training evolution, and her first as an adult, she is testing for her 3rd Degree Blackbelt in March! 


I am so proud of and grateful for her, and all the amazing Blackbelt Leaders who have grown up at KMMA.

   And proud and grateful for those we are building today! 


They are the product of our product, and the why and the reason that we do what we do.

I’m grateful for them and I’m grateful for you.


Students, thank you! 

And if you make it to class tonight, you get to give Sensei Mac her birthday kicks. 🙂


Parents, thank you! 

If it weren’t for you trusting us with your kids, we couldn;t do the good work that we do!

This to those of you on the benches, and those of you training too!


FInally, if you aren’t a part of our KMMA Family yet, I hope you’ll join us soon.

I can’t wait to serve you!
