ABOUT US
Founded by Sienna & Jonathan Olson, DC
Strength. Strategy. Wellness that lasts.
We didn’t start SLO Rx because we wanted to be another coaching company. We started it because we’ve both seen what happens when people, especially women, are ignored, dismissed, or made to feel like their struggles don’t matter.
Sienna’s journey started when she watched her mom get brushed aside by doctors, left without answers, and forced to figure things out alone. It lit a fire that still fuels her today:
To help women feel strong in their bodies—so they can use their voices, make bold decisions, and never feel powerless again.
That’s the heartbeat behind everything we do at SLO Rx.
Because we believe strong women change the world—not by shrinking, but by standing tall in who they are.

Dr. Sienna Olson, D.C.
Founder | Women's Health & Strength Coach
With a doctorate in chiropractic, a master’s in sports medicine, and over a decade of experience, Sienna helps women build lean muscle, increase energy, and reclaim confidence without extremes.
Her approach blends sustainable fat loss, strength training, hormone-conscious nutrition, and longevity-focused wellness. No gimmicks—just what works.
She’s coached hundreds of women through fat loss plateaus, metabolic burnout, and all-or-nothing fitness cycles—helping them finally feel strong, capable, and grounded in their bodies.
And she’s lived it too.
After competing in bikini bodybuilding and gaining 40 pounds post-show from hormone dysregulation, Sienna had to unlearn toxic fitness culture and rebuild her health from the inside out.
Through reverse dieting, strength training, and healing her metabolism, she lost 40+ pounds over time—without obsession. Now, she’s the leanest and strongest she’s ever been, with the freedom to live.

Our Philosophy
We don't do perfectionism, punishment, or pressure.
We do structure, strategy, and sustainability.
We believe:
Your health should work with your life—not against it.
Real change happens when coaching meets compassion—and leads with empowerment.
The best results come from methods that evolve with you, not ones that demand you conform.
Our Mission
To help you feel powerful in your body again—without burnout, extremes, or endless restarts.
To give you tools, not rules.
Clarity, not confusion.
Support that builds strength—not stress.
To create fire—and help you keep it burning.
Because when a woman feels strong in her body, she speaks with more confidence, leads with more clarity, and stops asking for permission.
