Hi! My name is Kaci Peniston and I’m a CF-L2 certified coach here at S3. Athletics have always played a very important role in my life. I started CrossFit about 13 years ago when I was 8, and I wouldn’t change it for the world. I also ran Track & Field in high school and have been very involved in Powerlifting in the past. Coaching, personal training, and teaching absolutely anyone who wants to better themselves is my favorite thing in the world. We would love to help you become more confident, healthy, and positive!

That passion led to the creation of S3—a place where individuals of all fitness levels are welcomed, challenged, and encouraged. Outside the gym, Rodney enjoys family time and values faith. He is married to educator, Krista Horning, and has two beautiful daughters, Ella Kate and Emmalyn. Above all, Rodney is committed to helping members build strength that carries into everyday life.
