We help people become hooked on fitness through making it fun, un-intimidating, and by meeting them where they are at regardless of prior experience or current practices. We love to share the method of becoming comfortable with fitness in order to bring vitality into our everyday lives.

Why do we want to do this?

Because we once were in a place that fitness was a struggle for us.

Each of us started our fitness journey alone and had too many false starts than either one of us cared for.

Once we found CrossFit (Steve in 2006 and Anna in 2010) the frequent setbacks and stutter starts lessened significantly. We are by no means “there”, perfect, or finished with our wellness journey because we came to learn it is a lifelong pursuit.  In that pursuit we would like to have as much fun as possible.

We each found CrossFit for a different reason than for what keeps us in it… let’s face it, we wanted hot bods (still do!) but as we grow older and more steeped in fitness we realize this is the means to help us experience vitality as we continue in life.

In the past decade we have watched our families grow older and struggle more and more with mobility, conditioning, flexibility, and stability. Consequently their worlds grow smaller in terms of what they can do, where they can go, their confidence, and the amount of energy they have.

We also have both witnessed individuals come from a deconditioned state to grow stronger, abler, and more confident. As their coach we want to make sure this isn’t just a short layover in health and wellness, we want to help them experience good health for the long haul.

Steven Williams

I found CrossFit in 2005 as part of a martial arts class that I was taking. I was a little intimidated by the workouts posted on the CrossFit main page and started out picking and choosing the workouts that I wanted to do on my own in our company gym. I quickly realized that the workouts were more effective then anything else that I was doing. I started bringing friends to the gym to show them CrossFit and finally attended a Level 1 certification in 2009.

Since that time I’ve coached at 2 other gyms in the Aurora area before opening CrossFit Banshee. Helping others learn to achieve their fitness goals has become a passion of mine, and I’ve spent 1000s of hours at the gym helping people reach a new level of fitness through CrossFit.

Anna Smith

From as young as I can remember, I was involved in sports and had my fair share of testing different athletics (Soccer, Gymnastics, Track, Volleyball, Tennis, Skiing, Snowboarding, Kickboxing) to find the ones that clicked for me.
Then my mid-twenties hit and I had a lull in playing sports, at that time I loved to hike but I also loved the great New Mexican food. I gained a lot of weight and became de-conditioned.

As I neared my thirties and realized I didn’t feel good and I didn’t like how I looked. I tried to get back into working out. There were a few stutter starts with a general gym membership at the large gym by my house.

In early 2010 I realized I couldn’t do it on my own and found a CrossFit gym. I had never heard of it before but was very intrigued by the idea of it. Almost immediately I loved the community and support and the fact that the workout was different every day. I lost 80 pounds and with the success I found through CrossFit and better nutrition, I felt the need to help others discover and create their wellness lifestyle.

Francina Taveras

Crossfit changed my life. Back home, in Dominican Republic, I used to be the girl who went home to watch TV, do homework, eat and then sleep to do the same thing the very whole week. I was never active or played any sports.

The story changed during my early 20s when a coworker and I started to do some workouts at a park. I just wanted “to be skinny” (Soon I learned to accept my under construction athletic body type). With time I was doing some exercise at least 3 to 4 times a week.

When that friend moved on to a new chapter in her life, I was again alone and with a weak willpower. I would go to a park and run almost every day like 2 miles and do some movements for lower body until one morning I ran into a group that led me to my dearest friends and CrossFit pals. We would get together during the week at a regular gym and then train together on gymnastics and other more cross training related WODs every Sunday.

Then one of my CF friends got his CF-L1 and more structure came along to all the stuff we were doing already. I took a couple classes for free and by the time I had to move to Colorado I asked my new boss only one thing: Is there a CrossFit gym nearby?

Once I arrived to Banshee, I didn’t have much faith in myself, but with this family I have learned that the body is capable of things beyond what our mind can imagine. In one year I have achieved goals that seemed far away and now I am CF-L1 certified.

I am a passionate Dominican who loves helping people to see that the body can achieve much more than we think and that the first step to see changes is to start doing things differently.

John Peterson

John was introduced to CrossFit in early 2016 when he joined CrossFit NYC with his girlfriend. The two of them were looking for a fitness modality they could practice together. John had been a collegiate Track and Field athlete and preferred high-intensity aerobic training. Julie, however, preferred hypertrophy style weight training. They found a great merger of those two training styles (and so much more) in CrossFit.

John began coaching at CrossFit Banshee as an L1 trainer in September 2019. Before this, he coached many other athletic modalities. He started his coaching journey as a ski and snowboard instructor, which he did avidly for 6 years, during high school and college.

After college, where John competed on NCAA track and cross country teams, he coached running programs with elementary through high school students. Track coaching led John to a role coordinating youth programs at a national sports company, New York Road Runners (NYRR). With NYRR John coached a summer running program for youth with low exposure to athletics.

He also facilitated trainings for DOE teachers on the efficacious application of fitness programming, based on a physical literacy and long term athlete development model. He also ran intro clinics for new track and field coaches, as well as clinics on inclusive practices in youth sport coaching.

John is excited to be a member of the team at CrossFit Banshee and is having a great time helping the community achieve their health and movement goals.

I started Crossfit in 2013 because I wanted to get better at roller derby. (A full-contact sport where we wear roller skates and skate around with our underwear on the outside of our pants). At 33 I was struggling to compete with younger skaters and I didn’t have enough size and power to make the rosters for the traveling team. I had a friend who started doing Crossfit for the same reason so I went to check out his gym. I liked the short intense workouts and loved Olympic weightlifting. Because of the extra work I was putting in and strength I gained, eventually I got to compete at the International Championships of Roller Derby in 2017. In 2018 I found myself coaching roller derby and also coaching as a management consultant professionally. It didn’t occur to me when I signed up to get training in CrossFit fundamentals (Level 1) that I was educating myself to be a CrossFit coach as well. My favorite thing about coaching is watching people master new movements, find new strengths and excel as the amazing humans they are. I love our community because it motivates and provides support in such a way that it’s easy to stay engaged.
