Master Katie Medina | 6th Degree Black Belt


I became involved in taekwondo 24 years ago. I watched two of my three kids train for a year before I finally decided to give it a try myself. I enjoyed it enough that after my kids quit, I continued to train. There are several reasons I have continued to train, but primarily I enjoy the classes, appreciate the regular exercise, and like the fact that there is always one more goal to achieve. Now that I have attained the status of Master, I still want to continue in order to help others reach their goals.

Colin Liska | 2nd Degree Black Belt


I'm Colin Liska. I originally started Tae Kwon Do back in 2002, when I was 7 years old. My mom signed me up believing it would be something I would be good at it and enjoy doing. I started at Master Todd Peckham’s National Tae Kwon Do Center in Wisconsin Rapids. After about a year, Master Peckham stepped down and Master Tammy Alekna took over the school. Shortly after the transition, the Wisconsin Rapids branch was closed down, however, the Adams-Friendship branch remained open, and I continued there. After about a year there, there was a division in the school. I left Master Alekna’s to join Master Valerie Holland’s A-F Tae Kwon Do since she had a branch in Rome, which was closer to where I lived. Around 2007, I was playing soccer for school, taking my regular Tae Kwon Do classes in Rome, and having become a Recommended Black Belt, Master Holland wanted me to get more instructing experience at the Adams-Friendship branch of her school. My schedule was so crowded, I decided to quit Tae Kwon Do to focus on school and soccer. After graduating college in 2019, I decided to get back into Tae Kwon Do and I joined Park Institute where Master Chrystal let me start as a Green Stripe given my prior experience and as a way to refresh me in forms and techniques. Looking back at all of the things I've learned from Tae Kwon Do, I feel really proud of how far I have come. I have been able to go from a White Belt up to a Recommended Black Belt, quit, restart, and work my way back up to be a Black Belt instructor. There have been forms I have messed up, board breaks I have struggled with , and a lot of sparring matches I have lost, however I still stuck with it and did not give up. I also need to note that a big part of what makes Tae Kwon Do great is the people I've met. From the instructors to my fellow students, they have all contributed to creating a family-like environment. They provide inspiration and encouragement to one another like I've never seen anywhere else.
