About Social Mulli

Started by a former owner who got tired of being lied to.

Marketing for gym owners and local businesses who are done being promised the world.

The founder story

She lived through it before she built the fix.

Danelle owned gyms for seven years and grew the training programs inside them, built around helping members stay strong as they age.

What started Social Mulli:

Gym owners would never believe “lose 50 pounds in 30 days.” But they will fall for “fill your gym in 30 days” every time.

Same lie. Different industry.

So we fix the fundamentals first, then spend on ads. Honest, consistent, and in your corner.

The core belief

Marketing is not a magic pill. Neither is weight loss.

Both take consistency and someone in your corner. That is the REPS Method.

Who you actually work with

Two people. Both answer their phones.

No account managers. You work with us.
