Step 1: Before your initial appointment, our health coach will schedule a free 30-minute consultation to acquaint you with our NGI package options and to set up your patient portal.

After this, there are a few options. 

Option 1: Most patients begin with a 3-appointment assessment process. 

This process begins with a 1-hour appointment with our health coach who will assess environmental and emotional triggers. The health coach may offer first line of defense strategies that assist in the reduction of environmental exposures and guidance on mind-body techniques to help manage stress.

A second 1-hour appointment with our nutritionist will assess current dietary intake and gastrointestinal symptoms. This appointment will allow for an analysis of total caloric intake, vitamin and mineral status, possible dietary triggers, bowel function and overall wellness. These appointments are designed to obtain accurate health information to be relayed to the primary provider and are not designed to execute a complete health care plan.

The final, two-hour intake appointment will be with your primary provider (either Dr. Christy Williamson, MS, CNS, DCN or Dr. Jessica Pizano, MS, CNS, DCN) and will synthesize findings from the first two appointments, explore possible root causes of the illness, review laboratory findings and begin the framework for a plan of action. The total cost of this service is $700 divided over 2 equal monthly payments of $350/month.

Effective November 1, 2019:

Dr. Christy is moving to a 4-appointment intake package. After the 3rd appointment with Dr. Christy, there will be a follow up appointment to discuss testing and execute on abnormal findings. Depending on the nature of the testing, this appointment will either be with the CNS or with Dr. Christy.  The cost of this package will be  3 equal payments of $375. 

Option 2: Initial Consultation with the primary practitioner of your choice ($450)

In this scenario, you will meet with your primary provider first, then she will decide after your initial consultation if you need to spend time with the health coach or nutritionist or if a package may be the best choice for you. These appointments are all at the billable hours rate. 

For pricing per specialist, please see below. 

Effective November 1, 2019: Option 2 for Dr. Christy will be $550
