Founded by Erin Peterson, FemTribe is one of the most respected health and wellness brands for women in the field.


My name is Erin Peterson and I currently live in Denver, CO. I moved to Denver four years ago because I was dancing professionally for a few modern and jazz companies. In addition to my dance career, I am also a NASM (National Academy of Sports Medicine) and AFAA (Aerobics and Fitness Association of America) licensed personal trainer with specialties in women, women's weight loss, and sports performance. In addition to training clients one-on-one, I also teach group exercise classes, run boot camps, and teach Zumba.

My History: How I got to Denver and what lead me to establish FemTribe

I grew up in Knoxville, TN with a very athletic family. On weekends we were constantly driving up in the Great Smokey Mountains National Park (only a short 45 minute drive) to go hiking, rock climbing and camping. My family also owned a boat and couple of jet skis, so during the summer months, water sports were very popular, especially in that southern Tennessee humidity! I loved wake boarding and water skiing, and would spend all summer perfecting my techniques.

My mother is really into horses, so she made my sister and I take equestrian lessons from the time I was born. While, I ended up not particularly liking the sport as much as some others, my younger sister still rides and competes to this day, and has become an extremely talented and accomplished equestrian rider.

In addition to my active family, I also played about every sport while in school. I absolutely loved soccer and basketball, but also played volleyball and ran track. All the while, I was still dancing;  studying ballet, modern, horton, and jazz. In high school, it became time to choose which sport to devote my time to, and without hesitation, I knew it was dance.

Throughout high school, I dedicated nearly every waking moment to dance. I was in a pre-professional performing company where we performed a variety of styles including classical and contemporary ballet, modern, jazz, and contemporary. After graduating high school, I attended the University of Iowa on scholarship. While there, I received my BFA in Dance with high honors and distinction.

It was during my sophomore year of college when I received my Zumba license and started teaching twice a week at the University Rec Center. While there, my fitness manager at the time told me that I should consider personal training. So with that, I studied up and became an AFAA licensed trainer.

Three days after graduating from Iowa, I packed up and moved across the country to Denver, CO where I had signed a contract with my first professional dance company: Kim Robards Dance. I spent a year there and then started dancing for Hannah Kahn Dance and Apex Jazz Dance. In order to supplement my dance career, I got a job as a personal trainer at 24 Hour Fitness and started teaching Zumba at Denver University a couple times a week.

Fast forward, five years later and my passion for fitness and women's health is still burning in my heart. I started graduate school at Regis University working towards my Master of Arts in Counseling where I am a counselor in training, studying to be a clinical mental health counselor (CMHC) and a licensed professional counselor (LPC). 

Why FemTribe?

As a trainer, I work with a plethora of different body types, personalities, ages, and genders, but my specialty is women and women’s weight loss. I love helping people learn about their bodies and showing them healthy ways to reach their individual fitness goals. In today’s society, it is so easy to get caught up in what media wants us to look like (and this is especially prevalent for women), so when I work with clients, I focus on changing their perspective of their body and fitness from a healthy and acceptance based lens. This is not to say that we can't set goals and work hard to achieve them, but we do so because we love our bodies, not because we are trying to punish them.  

I got into personal training because I wanted to help people learn how to love and shape their bodies into something they are proud of. As someone who has struggled with an eating disorder, I aim to educated women about their bodies from a place of love and acceptance. And how to fight for the body they have.

With FemTribe, I want to further help my clients, other women, fitness fanatics and whoever is on a journey to better health and self-love, to explore healthy recipes, challenging exercises, motivational thoughts and discussions on current health topics. Fitness has changed my life in so many wonderful and powerful ways, and it is my hope that I can pass on some of the knowledge I have gained through my journey thus far, in order to help others.

Casey Fitzgerald 

Brand Ambassador, Blogger

If the picture didn’t clue you in already, Casey has the privilege of being Erin Peterson’s younger sister.  Born and raised in Knoxville, Tennessee, Erin and Casey grew up living a very active lifestyle from a young age. Track, cross country, dance, volleyball, basketball, and particular for Casey, riding horses, kept them on a very busy schedule nearly every day. This developed an innate love of teamwork, fresh air, exercise-related stress relief, and overall health.

Casey graduated from the University of Tennessee in 2015 with a Marketing and Business Analytics major and minor in Psychology. She has a passion for people, numbers, and making the world a better place.

Since graduation, Casey accepted a full-time job as a project manager for the printing company, RR Donnelley. It was an unusual and shocking change for her to go from her very active lifestyle to sitting behind a desk a large part of the day. This has given her much material to blog about, as well as the inspiration to find a strategy that incorporates work success with a healthy balance of exercise and personal health. Casey is a huge believer in women’s rights and wishes that every woman could see how beautiful they are. Everyone is unique and has something to offer, and it is one of Casey’s goals to help people see those qualities within themselves. Afterall, weight is only a number.


Katherine Keel

Brand Ambassador, Blogger, Ski/Swim/Cycle Expert

There must be something in the water in Knoxville, TN, as Katie Keel is yet another FemTribe member hailing from the beautiful Smoky Mountain region. An lifelong outdoor enthusiast, Katie tried nearly every sport growing up and loved them all. 

She chose to focus on swimming, and accepted a scholarship to the University of North Carolina at Chapel Hill, where she excelled both academically and in the pool. Throughout her career, Katie attended numerous Grand Prix meets, Long Course and Short Course Nationals, Atlantic Coast Conference Championships and last but not least, finished her career by competing in the 100m breaststroke at the 2012 Olympic Trials. 

Graduating with a degree in Journalism (Marketing / Advertising), Katie squeezed every ounce of fun out of her time in Chapel Hill. After moving to Colorado five years ago, she's truly embraced the active community here and has been known to double dip when the weather is great- ski in the morning, bike in the afternoon! She's dabbled in triathlon over the years, and finished her first full Ironman in 2015. Backcountry skiing and mountaineering have recently captured her attention, but Katie is truly happiest outside- regardless of what the sport is. She is incredibly passionate to help other women get involved and break into the heavily-male dominated outdoor industry. 

In her daily life, Katie enjoys a multitude of activities- skiing, snowboarding, rock climbing, road & mountain biking, yoga, triathlon, swimming, exploring, eating, getting lost in the woods, camping, photography... the list goes on. If it takes place outside, chances are she is probably into it.
