About Us

About in2GREAT Functional Medicine

Our number one priority at in2GREAT is to ask and answer one question:


We ask questions like:

Why are you feeling depressed?

Why are your hormone levels not where they should be?

Why are you having autoimmune issues?

Why do you feel bloated all the time (or after you eat)?

Why is your hair falling out?

Why are you crashing in the afternoon but are unable to sleep through the night?

To some, these may seem like questions without answers. At in2GREAT Functional Medicine we ask why because we want to look past the symptoms you’re experiencing and discover the underlying forces driving those symptoms.

Your symptoms may be genetic. They could be due to environmental factors or toxins. They could be occurring due to an infection, a nutritional deficiency, or hormone dysregulation.

By asking why, we can identify the root causes—showing us how to fix the why.

Functional Medicine: A Different Approach

More than ever, our society is plagued by sickness. Heart disease, diabetes, mood disorders, autoimmune conditions galore, cancers… we are experiencing these ailments at unprecedented levels. Lifestyle and inflammatory diseases have become an epidemic.

Traditional healthcare’s go-to tools are drugs and surgery. Together, they’re used to treat symptoms, often with little concern for side effects (because there is always another medication to treat the symptoms of the side effects and another medication to treat those symptoms… and on and on).

Unfortunately, the conventional healthcare system isn’t designed around the needs of individual patients. It is symptom-focused, urgent-care-minded, and linear. If you have this symptom or that disease, you receive this treatment or that protocol.

Many of our patients have gone through the standard medical system. They’ve endured medications that were the “standard of care” for their condition—but that didn’t actually solve their health issues, let alone get to the root cause. As often as not, these medications created new health issues for our patients.

The conventional medical approach doesn’t use the proper strategy or tools to get to the root cause of complex chronic conditions.

We believe there is a better path to wellness.

The in2GREAT Functional Medicine Experience

When you work with us, you’ll find that we have a different approach: functional medicine. Functional medicine is science-based, individualized, and patient-centered. Its aim is to address the underlying causes of disease & illness and to promote optimal wellness.

Here’s what you can expect when you come to in2GREAT:

Comprehensive consults.

We spend a significant amount of time talking with each patient. We listen to your history, learn about your life, and look for the interactions between genetic, environmental, and lifestyle factors that can influence chronic disease and long-term health.

Cutting edge laboratory testing.

We do thorough lab work based on your individual needs, which allows us to accurately assess your unique situation.

Data-driven care.

We use objective data from your lab testing to make better decisions about your health and wellness needs.

Supportive therapies.

We employ a variety of tools to support you on your path to wellness, including: nutritional supplementation, lifestyle coaching, dietary coaching, and IV nutritional therapy.

Ongoing optimization.

Through our TotalCare programs we can help you to enhance performance or better cope with (and potentially overcome) chronic ailments.

Using these tools, our aim is to optimize health, encourage a prevention-focused lifestyle, and to empower patients by providing them with the education & tools needed to take back control of their health.
