Our Founder
Tammy Zsembik created Stay True with a vision of helping people better understand their bodies and take meaningful steps toward long-term health. She believes that wellness should be approachable, practical, and rooted in education so individuals feel confident making decisions that support their overall well-being.
Her passion for functional health and personalized care has shaped the mission behind Stay True: to provide thoughtful guidance, trusted resources, and supportive care that helps people move beyond quick fixes and toward sustainable health.
For Tammy, the goal is simple—help people feel better, understand their bodies, and build a foundation for lasting wellness.
Why I Started Stay True Functional Health
A Letter from My Soul to Yours
I wasn’t always the woman you see today—leading, creating, healing. For a long time, I was just trying to survive. In the late ’80s, something was taken from me—something that should never be taken from anyone. It was a trauma that left scars you couldn’t see. Back then, silence was the norm—and that silence became my prison. I carried the shame, buried it deep, and kept moving forward… because that’s what strong women are told to do.
The Beginning
In 1993 and 1996, I became a mother to my two greatest blessings. Motherhood changed everything, but it was brutally hard. I worked three jobs, stretched every paycheck, and relied on quiet help from a food bank. I married young, but after 22 years of struggles, I found myself divorced and starting over. There were sacrifices my children may never know—but they were worth every single one.
The Challenge
In 2007, a head-on collision with my daughter nearly took our lives while three teenagers did not survive. That moment split our lives into “before” and “after.” Trauma left me numb, disconnected, and without dreams—but something in me refused to let that be the end.
The Breakthrough
I clawed my way back through prayer, functional healing, and mindset work. I was blessed to remarry a man whose spirit aligns deeply with mine—his love became a grounding force, bringing balance and peace when I needed it most. Through it all, I discovered the truth: You can heal. You can rewire your thoughts. You can reclaim joy. And not just survive—but soar.
The Impact
Stay True Functional Health was created to bring functional wellness closer to our community. Our Findlay space offers carefully curated, practitioner-grade supplements and access to trusted telehealth providers focused on hormones, gut health, metabolism, and sustainable weight support. We’re building a place where real healing can begin. In the future, this mission will expand through Valinor, a digital platform designed to support daily wellness and long-term health habits. For now, our focus remains simple: bringing the tools, care, and guidance our community deserves.
Let me walk with you.
Let’s break the chains together.
Let’s change the narrative and rise into the life you were created for.
With all my heart,
Tammy Zsembik

Before I started using the products at Stay True and seeing their functional medicine practitioner, I was experiencing depression and anxiety that I didn’t know I had, which led to overeating and weight gain. I also have a family history full of disease looming over me. I started my journey at 320 pounds and size 24. Today I am 246, size 18 and still making progress

I started my journey at 249 pounds and a size 22. Today I am 199 pounds and size 14. This is the first time I have been under 200lbs in over 20 years and I am still losing weight.
I am no longer diabetic and I do not have to take any medication for it. My blood pressure is normal. I have more energy and I am happy.
