Hi Dr Saurabh,
My mother’s ongoing consultation with you has been disrupted since your departure from Felix. Could you kindly provide an alternative contact number, channel, or email where you can be reached for further consultations?

Good evening, since I have shifted to Ambedkar Nagar Hospital dakshinpuri, all my erstwhile patients are being handled by other dermatologists at the Felix hospital. You may discuss with them. I suggest you show my prescriptions to them so they can better understand the line of management and make alterations.
