Functional Medicine Membership

So that we can accurately address your individual needs as a Functional Medicine patient, there is a detailed questionnaire that we send and ask you to fill out prior to your first appointment. During this appointment, Dr. Grewal will discuss the information reviewed from your questionnaire as well as further her understanding of the issues you are experiencing. This appointment is critical for creating the best-personalized path towards your wellness. As an Integrative and Functional Doctor, this may involve both traditional and holistic approaches in order to address the root causes of your issues. Dr. Grewal may recommend other specialists in order to achieve a cohesive plan for your overall health.

After your first visit at the Grewal Center, future follow-ups may be arranged in person or over the phone. 

We provide our patients with the greatest level of personal care that is out of network for all commercial insurance carriers, Medicaid, and Medicare. Some insurances may cover medical services and laboratory tests we perform. If you would like to submit our visits to your insurance company we can provide necessary paperwork which you yourself can submit for reimbursement to your insurance. However, you cannot participate in the membership for insurance reimbursement. Your visits must be paid in full amount at the time of your appointment.
