  • We realize that people usually don’t stick with a fitness program because they don’t enjoy it, but we will show you that being healthy can be fun and rewarding.  We will challenge you every single day in unique and creative ways that will be fun, exciting and keep you coming back for more. 
  • Our goal is to help you change your life by making you stronger, healthier and more confident than you’ve ever been...and we’re 100% dedicated to helping you achieve the results you want.  
  • The sense of community at CFSD is powerful.  CFSD is a special place filled with incredible people that have become friends and family with one another both inside and outside of the gym.  This camaraderie will give you the strength, confidence and motivation to give your best effort.

Kathy Healy-Blasko - Co-owner / Nutrition & Wellness Coach / CF Level 1 Coach -CF Kids Coach

Kathy got involved in fitness nearly 20 years ago and literally and figuratively fell in love with it.  Soon after, she became a personal trainer to help others feel as good as she did and to help them reach their goals. Kathy felt troubled though early on in her fitness career as her clients followed all of the rules that the fitness and nutrition industry put out there, but the health and wellness results weren’t coming. It wasn’t until her own health took a dramatic turn that she really woke up to the fact that everything people were being taught was wrong. She dove into the research and enrolled in nutrition school and became a certified nutrition and health coach to work towards healing herself and to teach people the true biochemical workings of a healthy body and healthy metabolism. Coach Kathy is a patient, trustworthy, and knowledgeable Coach whose mission it is to enable everyone to achieve an effortless relationship with food and to feel as good as they can…. once and for all.

MK Schnaars - CrossFit Level 1 Coach - CF Kids Coach

Coach MK’s passion for fitness began early as she participated in a number of sports, as well as enjoying hiking, backpacking and triathlons.  She tried her first CrossFit class in 2014 at the urging of a friend after feeling generally bored with the same old cardio and gym routines. After one class, she knew that she had found the challenging and exciting fitness regimen she was looking for. In January 2016, MK became a member at CFSD and quickly grew as an athlete and became one of its  most vocal and supportive members, often putting the needs of the others in the room ahead of her own. This level of selfless dedication is exactly what we were looking for in a Coach, so MK was invited to become a Coach at CFSD.
