Clarity in your body. Clarity in your business.

I help people heal and businesses thrive. In functional health, I uncover the root causes of chronic symptoms and create personalized plans for lasting wellness. Through One Degree Consulting, I equip financial advisors to build high performing, sustainable practices with clarity, strategy and systems that work. 

Your health. Your business. Your transformation - by design.

"Write the vision; make it plain... though it linger, wait for it; it will surely come."

-Habakkuk 2:2

"Where there is no vision, the people perish..."

-Proverbs 29:18

I live in Florida with my husband Marcus and love playing competitive cornhole in my spare time. I believe the words of Proverbs 29:18 and Habakkuk 2:2 — “Write the vision and make it plain… though it linger, wait for it; it will surely come.”

Whether you’re rebuilding your health or redefining your business, healing happens when vision is written—and you start living by design.

About Me

Jessica Rauscher FDNP, CLU

Founder of By Design | Functional Health Practitioner | Sales Consultant for Financial Advisors

I’m an entrepreneur at heart—but I didn’t always build life by design.

For years, I made decisions from urgency, burnout, and survival.

I learned most of what I know by doing it the hard way.

For 18 years, I ran a successful financial planning practice with over 700 clients. On paper, I had it all. But when my husband was diagnosed with sarcoidosis and offered a medication that could cause infertility, everything shifted. That was the moment I realized: if I wanted a different outcome, I needed a different approach.

As I searched for answers for him, I ended up needing them for myself. I became mysteriously ill—crippling anxiety, unexplained symptoms, and depression that eventually led to two years on disability. It took me digging deep and advocating for myself to finally uncover the truth: I had Lyme disease, mold toxicity, and co-infections.

I spent years taking continuing education courses alongside functional medicine doctors, and eventually became a certified Functional Diagnostic Nutrition Practitioner (FDNP). Today, I help others uncover what’s been missed—because I know what it’s like to be gaslit, dismissed, and desperate for real healing.

Alongside my health practice, I also founded One Degree Consulting to coach financial advisors in building meaningful businesses. After 18 years in that world, I know: strategy without identity doesn’t work. The same internal misalignment that wrecks your health can wreck your close ratio.

That’s the heart behind By Design:

To help you heal and build—through clarity, vision, and divine alignment.
