Steve and Anna were coaches with two Aurora CrossFit gyms before CrossFit Banshee. Along the way of establishing CrossFit Banshee, Steve and Anna earned level 3 and level 2 CrossFit certifications respectively. Before moving into our gym space in late 2013, we started out as Outside the Box, bringing CrossFit workouts to various grassy spaces around Aurora.

CrossFit Banshee has 4 additional CrossFit level 1 certified coaches that love to share their passion and experience with movement and fitness. In addition to CrossFit, we have also created a nutrition coaching program to help members create healthy lifelong habits.

    We offer workshops on various topics including health, fitness, nutrition, recovery, financial health, art, business, and more.

  • Showers

    We have two showers open to our members to use. Bring your own towels and soaps.

  • Cubbies

    We have a 16 self unit for you to store your personal belongings in while you work out.

    We offer various supplements through SFH to support you in your pre, during, and post workouts. We have a variety of CrossFit Banshee T-shirts and tanks. We also have refrigerators with Kill Cliff, FitAid, Caveman Coffee, and Perfect Bars for you to purchase.


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. During elementary, middle, and high school I played volleyball and skied as much as I possibly could; I loved every minute of it. Then in high school, I found tennis and was hooked! Skiing and tennis continued on into my early twenties. I became a ski instructor at Ski Santa Fe and taught beginners as well as young children.

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 in my twenties. 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. With the success I found through CrossFit and better nutrition, I was encouraged to get my CrossFit Level 1 certification in early 2011. I received my Level 1 in August 2011 and have been coaching since then (taking some time off to have a baby in between!).

I also found that I had a lot of questions coming my way about nutrition. In late 2013, Steve encouraged me to sign up for Precision Nutrition’s Coaching Program; I completed that in early 2014. I am now on my way to becoming a Super Coach with Precision Nutrition’s Level 2 Master Coach Certification (to be completed Sep 2016).

I have always been a very physically active person and was getting bored in the standard gym environment. After doing a bit of research on CrossFit I decided to give it a try. I started in 2014 and instantly fell in love with it. Not just with the style of workout and the constant variations, but also the community that is CrossFit. Working out in a group, encouraging each other, and helping each other accomplish goals is very rewarding. I took my Level 1 CrossFit course 2015, at first, to simply expand my knowledge of the sport and become a better athlete. Teaching has always been a passion of mine no matter what the subject, so I became a coach at CrossFit Banshee to share what I have learned and help others evolve their fitness and overall physical well being.

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.
