Frequently Asked Questions

Are you seeing clients in person?

We are currently seeing clients in person and via Telehealth.  We are located in Great Neck, N.Y.

Do you accept insurance?

We are out-of-network which means we do not accept insurance directly. However, we help our clients with reimbursement process providing you with a monthly receipt. In my experience, most my clients are reimbursed for 60% to 80% for the cost of their sessions if they have out-of-network mental health coverage. To know if your insurance policy has such out-of-network coverage you will need to contact the members number listed on your insurance card. Ask if you have out-of-network benefits, if there is a deductible, if deductible is met, and what percentage the insurance will reimburse. We will supply you with claims and bills to submit and then you can get reimbursed!
