Endocrinologist, Rheumatologist, GYN, Phyician assistant, primary doctor and many more. It really comes down to how 'up to date' the person is with HRT. To save a lot of time and disappointment call the office and ask if the doctor prescribes HRT or more specifically for postmenopausal women. I just asked Copilot to list doctors close by me that prescibe HRT. It showed me 4 options. One of them was my primary but did not show my Endocrinologist who manages my HRT.
