The functional medicine difference

A normal lab result is where we start looking, not where we stop.

For thyroid hormone to actually work, it has to be free, it has to reach the receptors in your cells, and it has to convert from T4 into the active T3 form. Standard testing rarely checks whether any of that is happening. We do.

What a detailed panel looks at

Inflammation
Cortisol & stress
Blood sugar
Hormone balance
Gut & GI health
T4 to T3 conversion
Adrenal & liver
Anemia

01
We listen first

Functional medicine starts with your story, not a rushed appointment. Your symptoms are the body asking for help, and we take the whole picture seriously.
02
We test in detail

Detailed functional blood chemistry looks for the blockers other panels miss: inflammation, cortisol from stress, hidden infections, blood-sugar and hormone imbalances.
03
We find the blockers

Too much estrogen, poor T4-to-T3 conversion, GI problems, anemia, adrenal and liver stress can all keep thyroid hormone from reaching your tissues. We map what applies to you.
04
We build your protocol

Natural treatment tailored to one person: you. The goal is genuine recovery, not endless treatment or a higher dose that never fixes the underlying problem.

Dr. Gil Kajiki

The practice began at home.

Eighteen years ago, Dr. Kajiki's wife, Kim, was suffering with night sweats, heart palpitations, and extreme fatigue. Her blood tests kept coming back normal. Already a physician with two decades of experience, he went back to school because of her, completing post-doctoral work with the Institute for Functional Medicine and earning a certification to practice functional medicine.

He found the clues in Kim's lab work that her doctors had missed. She did have a thyroid-related problem, he built her a protocol, and she is still free of symptoms today. For the last fifteen years, that work has become the whole practice: helping patients recover from chronic, puzzling symptoms that are so often thyroid-related.

Patient voices

Recovery stories, in their own words.

I would go to doctors, but they had no answers. I struggled for 15 years with bloating, fatigue, weight gain, swelling and hair loss before coming to Dr. Kajiki. After just one week of working with him, I felt so much better. After 4 months, the majority of my symptoms had improved.

JamieResults may vary.

Dr. Kajiki helped me figure out many of my triggers. It was nice to know that he had really listened to me. He is a kind practitioner, and I appreciated his guidance. He was extremely helpful in my healing.

Joy FerranteResults may vary.

After only 2 weeks of working with Dr. Kajiki, the majority of my symptoms are gone. The pain in my stomach and gall bladder are pretty much gone. Memory and brain fog are much better. I've improved 85 to 90 percent already.
