Hi, I'm Dr. Sarah Jonjak,

It was Christmas Eve in 1982, and I was a sick four-year-old unable to get off the couch. My parents, worried about my condition, called our local doctor. Growing up in a small Wisconsin town, we only had one physician outside the hospital. But he came to our house that night, assessed me on a holiday, and within an hour, I was back to my energetic self. That moment stuck with me—seeing the care, the dedication, and the impact of a provider showing up exactly when and where they were needed.

my journey into healthcare began with a moment I’ll never forget.

That memory planted a seed that grew into a lifelong passion for helping others. Over 25 years in healthcare, I’ve had the privilege of learning how the human body works—and how it sometimes doesn’t. My career in nuclear medicine gave me a deep understanding of how the body can malfunction, while my work as a pharmacist revealed the frustrating hamster wheel many people experience: a symptom arises, medication is prescribed, and the cycle continues.

What I noticed, time and again, is that the first recommendation for many chronic conditions is lifestyle changes—but the first action is often a prescription. I believe we can do better. Real health comes from understanding the root causes of illness, not just masking symptoms.

Frustrated with traditional healthcare options, I searched for a holistic approach and by good fortune found Chronicity and Dr. Sarah Jonjak.  Sarah created a plan unique to my individual needs, incorporating nutrition, exercise, and a review of my medications and dietary supplements. Sarah took the time to get to know me, and most importantly, she met me where I was - both metaphorically and physically.
