Meet Dr. Kathryn Zika, MD, IFMCP, FMACP

Dr. Kathryn Zika is a board-certified pediatrician and functional medicine physician who helps patients pursue healing with clarity, compassion, and a whole-person approach. She is an Institute for Functional Medicine Certified Practitioner (IFMCP), having completed rigorous training learning standards in functional medicine education, assessment and clinical application.

Her years in pediatrics gave her deep respect for strong clinical medicine and evidence-based care. But over time—through her work as a physician during the pandemic and her own personal health journey after a car accident—Dr. Zika began to see what so many patients experience: sometimes the standard model doesn’t go far enough. Symptoms are addressed, but the “why” is missed. And patients are often left feeling unheard, rushed, or stuck.

That’s what drew her to functional medicine.

After becoming a functional medicine patient herself, Dr. Zika began formal training in 2022 and completed certification through the Institute for Functional Medicine and the Functional Medicine Academy in 2025. She founded Steadfast Functional Medicine with a simple mission: to help patients move toward a life that is whole, grounded, and healed from the inside out—by identifying root causes, rebuilding foundational health, and creating a plan that fits the real life of the person in front of her.

What it’s like to work with Dr. Zika

Dr. Zika's style is thoughtful and practical. She takes time to listen, connect patterns, and guide patients step-by-step, so they not only understand what’s happening in their body, but also feel confident in what to do next. Care is personalized, focused on long-term resilience, and designed to reduce future risk—not just chase symptoms.

Life beyond the clinic

Dr. Zika is a wife, mom, and passionate learner. Her husband, Dr. Jacob Zika, is a chiropractor who shares her mission of putting patients first. Together, they blend conventional and holistic approaches in their home and practice.

Outside of work, Dr. Zika loves fitness, nature walks, music, travel, and interior design with her daughter. She serves in her church’s children’s ministry and finds joy cheering on her kids at their games and events.

That’s the space we’ve created at Steadfast.

There is wisdom in the body
There is purpose in your healing
There is power in personalized, science-based care
And there is hope for every patient who walks through our doors

Frequently Asked Questions

Clear answers to common questions about working with Steadfast Functional Medicine

What is Functional Medicine?

Functional medicine is a root-cause approach to care. Instead of just managing symptoms, it looks at how your genetics, lifestyle, environment, and nutrition are influencing your health. We use this big-picture view to design a personalized healing plan for your body, mind, and soul.

What conditions do you help with?

We help with a wide range of concerns, including:
• Chronic fatigue and burnout
• Hormone or thyroid imbalances
• Digestive issues (IBS, bloating, constipation, etc.)
• Autoimmune patterns and chronic inflammation
• Anxiety, mood changes, and stress-related symptoms
• Unexplained symptoms that haven’t improved with conventional care

If you feel “off” and haven’t found answers, functional medicine may be a fit.
