Looking for a gynecologist that understands endometriosis in Berlin

I had my diagnostic and excision laparoscopy in 2022 at the charité in Berlin. I did like the specialist there, but the endometriosis clinic would only have me as a patient for the surgery and one check up appointment afterwards, then I was discharged.

I know I can be referred there again if/when I need surgery for a second time, but I of course still need regular check ups with a gynecologist in the meantime.

I’ve found it so difficult to find a gyne who has more than a very basic understanding of the disease, and my current doctor refuses ultrasounds unless I pay out of pocket. So so I would love to hear if anyone has any recommendations in Berlin and surrounding area? I’m on public insurance.

TIA.
