Preparing for Your Visit
How do I submit my lab results and medical records?
Upload PDF copies of your lab results, medical history, and medical charts using the intake link sent to your email.
Do not email your records to our office. Records sent by email will not be processed.
How do I prepare for my consultation?
Upload only information relevant to the reason you are seeing Dr. Groysman. Please do not upload hundreds of pages of records; that volume cannot be meaningfully reviewed before a visit.
Please prepare:
- A two-page summary of your relevant medical history that you write yourself.
- Your current medication list.
- A list of your current supplements.
- Important test results or records directly related to the problem you want addressed.
All documents must be PDFs. Complete your intake and upload your information more than 24 hours before your consultation using the intake link sent to your email. Emailed records will not be processed.
Decide what you want to accomplish. At the start of your visit, Dr. Groysman will ask, “What can I do for you today?” Tell him whether you want an evaluation and treatment plan or help with a specific concern, such as POTS, dysautonomia, MCAS, hormone imbalance, endothelial dysfunction, or mitochondrial dysfunction.
The questions he asks depend on the concern you want addressed. Keep the goal reasonably focused, and allow him time to ask questions and gather the information needed for your evaluation.
Make the most of your appointment time. We offer 20-minute and 40-minute consultations. You decide how to use your time, but spending most of it telling your story may leave less time for evaluation and treatment planning. The visit works best as a conversation: explain what you need help with, then give Dr. Groysman the opportunity to gather the details he needs.
What should I check before my appointment?
Review your appointment confirmation and any instructions provided by our office. Confirm the appointment time and whether your visit is in person or virtual. If you are unsure which forms or records are needed, please contact our office before your appointment. Be prepared to pay in full at the time of your visit.
What should I expect during treatment?
1. Initial consultation. Dr. Groysman reviews your medical history, current symptoms, and previous treatments. Depending on your symptoms, diagnostic testing may be recommended. Your evaluation and results help guide an individualized treatment plan.
2. Treatment. The plan may include in-office procedures, such as stellate ganglion block (SGB) or epipharyngeal abrasive therapy (EAT), and at-home therapies, such as vagus nerve stimulation (VNS), when appropriate. Our team provides instructions for your prescribed therapies. Contact our office for preparation instructions specific to your scheduled treatment.
3. Follow-up. Follow-up consultations allow Dr. Groysman to review your progress and adjust your treatment plan. We typically recommend visits no more than three months apart.
Comfort and progress. What a treatment feels like and how soon you may notice improvement depend on the procedure and your individual condition. Discuss expected benefits, risks, discomfort, and recovery with Dr. Groysman during your consultation.
If you need clarification about something discussed, contact our office. New concerns require a new consultation.
Am I a good candidate for treatment?

- Post-traumatic stress disorder (PTSD).
- Immune system overactivation, including mast cell activation syndrome (MCAS).

Our approach combines evaluation, diagnostic testing when appropriate, and individualized treatment planning. Your consultation is the opportunity to discuss which options may be appropriate for you.
