Professional History
​
I graduated from UW - LaCrosse with a degree in Corporate Fitness and Minors in both Business and Coaching. I spent 4 years playing outfield for the women’s fast-pitch softball team in LaCrosse. Out of college, I continued to play fast pitch softball competitively but found myself wanting to do more for my fitness, so, I started running. After entering a few 5k’s and 10k’s, I had a few friends encourage me to consider running a marathon, to which I said “How far is that?” and immediately said “NO WAY”. Of course, it didn’t take a lot more to convince me that I actually could complete the distance with proper training. I managed to complete my first marathon in 3:09. Needless to say, I was hooked and then the challenge became the daunting task of running under 3 hours.
After a few years of running marathons, another friend suggested I participate in a triathlon, and thus began that journey. After 2 years into the triathlon world, I participated in my first Ironman distance race. I realized I really loved torturing individuals on an ongoing basis, so personal training seemed to be the perfect fit. I've been doing it ever since!

SPIN Instructor, Zumba Instructor
ADVANCED SENIOR FITNESS INSTRUCTOR - ASFA
Growing up with a mother who taught aerobics, group fitness has always been a part of my life.
Following the birth of my children, I found Spin to be a fun & rewarding way to lose weight and get into better shape. I quickly fell in love with it and wanted to help others do the same. So, in 2011, I became a certified instructor and began teaching at TriFitness Coaching in 2024.
​
I love being part of this community - promoting all of the offerings that we have and helping others find the best fit for themselves.

I have seen first-hand, through my life’s journey, the profound effect that endurance sports can have on your life. My goal for my athletes is to dare them to dream big, accomplish their goals and create an environment for a lifetime of enjoyment in whatever sport they choose.​
​
I found triathlon and endurance sports over a decade ago and have had the opportunity to complete multiple triathlons across all distances as well as several marathon and half marathon completions. There is nothing better than the community you find through endurance sports.
​
Whether you are an experienced endurance athlete looking to take your training to the next level or someone looking to complete their first sprint distance, let’s connect and see how we can partner on your journey…I can’t wait to get started!

Jack Hennen
Swim Coach
Growing up with a pool in my backyard I began my swimming career very young. I began competitive swimming at the age of seven, starting with swim clubs and eventually joining my high school team. During high school, I also ventured into coaching swimming and continued to do so, working with individuals of all ages and skill levels.
I love helping people reach their swimming goals whether they are swimming without stopping or getting under a certain time for a specific distance.
I would like to say I found the sport of triathlon at the age of nine, but it was my dad who found it for me. My first triathlon was the Chisago Lakes Kids Triathlon in 2009, and that was the start of racing every other weekend in the summer if not every weekend, or even sometimes two a weekend for over a decade. This continued into college when I joined the University of Minnesota Triathlon Club and competed in two races with them until I got sent home for two years due to COVID which abruptly stopped my racing career. Having successfully graduated from college, I am now determined to re-enter the competitive endurance world and continue pursuing my passion for swimming and triathlons.

Heather Ramsay
Yoga Instructor
I have been practicing and studying yoga since 2012. It was with strong encouragement from fellow yogis, husband, and friends that I took the next step in becoming a yoga instructor.
Heather completed the 200+ hour RYT program through Green Lotus Center in 2017 and is registered as an E-RYT 200 with Yoga Alliance. She held several wellness events and weekly classes at a 7 Vines Vineyard and instructed at Pure Yoga and YMCA.
Heather continues to grow and refine her skills as an instructor and student. She understands the body is ever changing. This is reflected in each class, removing judgment and expectations. Mindful of the breath and its vast benefits to the body and mind, this is where she begins and ends in each class. Heather instructs intuitively and will offer plenty of modifications and invitations to do what’s right for YOU.
Heather is married to her supportive husband Brady and together they have two teenage boys. Heather has a culinary degree from the Scottsdale Culinary Institute and now focuses on healthy, tasty food. She enjoys a very active lifestyle with her boys.
