Dr Eliana Dima has a surgery every Thursday in Guern behind the post office. Other days she is in Malguenac, rue de Guern, opposite the church. The phone number is 0297393634/0689827336. She speaks English and we have found her to be very attentive and helpful. At the moment she is away from the Guern surgery until after Easter so I expect it will be same in Malguenac. Hope this helps.
