It’s never too late to get healthy!

I can help you develop the habits you need to live a healthy lifestyle for those who are 55 and older.

Let’s Get Healthy

Meet Kristie

Sometimes, all you need is a guide to help and support you along the way. 

This is why I created Sustainable Change Fitness.

I am a health coach and certified personal trainer driven by a passion to help individuals 55 and older build sustainable lifestyle habits that will significantly improve function and movement.

I’ve spent most of my career in a professional role within the optical industry helping people see and feel better about themselves.

A mentor once told me, “Never lose your sense of humor”.  Great advice for almost everything in life.  With a positive attitude you can do almost anything you put your mind to!

For me, being outside participating in endurance activities, such as cycling, running, swimming, and hiking allows me to de-stress and clear my mind, while building strength.

This includes the Chicago marathon, century bicycle rallies, including the Texas Hotter’N Hell Hundred, The World’s Most Beautiful Bike ride in Tahoe, and many others.

If you want to move from frustration to confidence when it comes to your health, it starts with small sustainable actions toward healthy habits.

“I’ve not had much success in the past sticking with an exercise routine. I’ve tried many times and lasted for a while, and then just gave up. Kristie has a great way of connecting and making you feel comfortable being yourself.”

-Julie M.

“She has helped me to see that exercise can be fun, and something I now look forward to. She is a great coach and I’m learning how to make small changes in my schedule to make this time around a lasting change.”

-Julie M.

The dedication and attention Christie provides for my husband with Parkinson’s disease is amazing! She is always welcoming, creative and encouraging with the exercises in each session. My family has seen a positive difference when my husband attends his classes with Christie. She is the best!
