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.

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.

Mast Cell Activation Disorder Pathway

Multiple Appointments 

One-Hour Sessions

 Due to the complexities of mast cell activation disorders, NGI has created a personalized approach to managing and treating this disease. NGI will work closely with your medical providers or assist in appropriate referrals to such providers. The packages are divided to keep overall costs manageable and to allow for flexible, personalized, precision care. Some patients may require all of the options below while others may only require a portion.

Phase 1: All  patients will begin with the Introduction to the Practice Package. After the final appointment with either Jessica Pizano, MS, CNS, DCN or Christy Williamson, MS, CNS, DCN, a follow up package will be suggested.

Phase 2: Mast Cell Intensive Care: For patients too sick to work intensely on their nutrition status, we may suggest working exclusively with your primary provider until stable enough to work on implementing dietary changes. These patients will be seen every four to eight weeks as decided by the practitioner. All appointments, emails and phone calls will be billed on the quarter hour at the $225/hour rate. Once the patient has the appropriate medical team and support, their primary provider will “graduate” them to the Mast Cell Activation Package.

Phase 3: Mast Cell Activation Package: This package includes a series of 4 appointments over the course of 4 months. You will begin with a follow-up consultation with either Jessica Pizano, MS, CNS, DCN or Christy Williamson, MS, CNS, DCN followed by a 1-hour appointment with the nutritionist to implement food and/or supplement changes. The next 1-hour follow up appointment will be with the nutritionist or the health coach depending on patient needs. A final appointment will be with the primary provider to discuss next steps and decide if additional appointments are necessary. This package also includes 2 hours of billable hours to address patient questions via email or phone as required. All additional emails and phone calls will be billed on the quarter hour at the $225/hour rate. The total cost of this package is $1200 divided over 4 equal monthly payments of $300/month.

Phase 4: Mast Cell Maintenance Package: Once the patient has reached a sustainable improvement in health, they will be offered the Mast Cell Maintenance Package. This package includes 4 appointments with your practitioner and 2 appointments with the health coach or nutritionist over the course of 12 months. This package includes 6 hours of billable hours. Billable hours may be used to address additional questions in the format of email, phone call, or scheduled appointment. This package is $215/month for 12 months.
