Hi, I'm Coach D.
It's not magic. It's mindset.

My name is Derith Cass, aka Coach D., and I'm a lover of travel, fitness, and the human connection. As a 25+ year veteran in the fitness industry, I have coached people from all walks of life as they begin, transform, and endure their individual journey to healthfulness & habits. I've taken my years of observation and training to create this one-of-a-kind FIERCE Habits by Design handbook. Plus, you'll receive a coaching session with me so we can make sure you know how to put this handbook into action!

It takes a “FIERCE Village” to motivate you and encourage you to show up daily, but it takes a Fierce leader to inspire you each and every day you whether it’s at the Garage gym or participating in Coach D’s motivational programs designed for overall wellness from literal head to toe. Living FIERCE is now a part of my daily routine and has changed the way I view myself.  At 54 I feel stronger than I did at 34.

I could not recommend Coach D. more highly!  She helped me make and keep changes!  She is so unbelievably kind and concerned about every one of her clients.  She has an amazing way of knowing each woman’s challenge and checking in with them to make sure they are working at the right level.  Coach D. has created a tribe of women that feel connected, supported and pushed! Coach D is the best!!!
