Wellness That Works With Behavior — Not Against It

TC Momentum was created for people who are tired of starting over.

If you’ve ever felt like you know what to do for your health but struggle to stay consistent, you’re not alone — and you’re not failing. Most wellness plans ignore one critical factor: human behavior.

At TC Momentum, I do things differently.

Meet Tiarra Cupp

I’m Tiarra Cupp, a Board Certified Behavior Analyst (BCBA), Certified Wellness Coach, and Certified Nutrition Coach with over a decade of experience.

My background is rooted in behavior science — understanding why we do what we do and how to create systems that support long-term change. People are motivated, capable, and willing… but stuck in cycles of all-or-nothing thinking, burnout, and unrealistic expectations.

I founded TC Momentum to bridge the gap between behavior science and everyday wellness.

Why TC Momentum Exists

Traditional wellness often relies on motivation, restriction, and perfection.
Behavior science tells us those approaches don’t last.

TC Momentum exists to help you:

• Build habits that fit your real life

• Replace guilt and pressure with structure and clarity

• Learn how to work with your behavior instead of fighting it

• Create routines that are flexible, realistic, and sustainable

This isn’t about quick fixes or extreme plans.
It’s about learning skills you can use for life.

Credentials & Experience

• Board Certified Behavior Analyst (BCBA)

• Certified Wellness Coach

• Certified Nutrition Coach

• 12+ years of experience in behavior change

• Specialized focus on movement, nutrition, stress, and sleep

My work is guided by science — and delivered with empathy.

Beyond the Credentials

I’m also a mom, a business owner, and someone who understands how demanding life can be. TC Momentum was built with that reality in mind.

Progress doesn’t have to be perfect to be powerful.
