Hi,
Would you mind saying exactly where you live? I am in Alexandria and I have gotten all of my trans-related healthcare taken care of at Whitman Walker Health in DC. I also know of the Fan Free Clinic in Richmond. While I'm sure there are independent endos around who would be able to help you, those are two surefire places to go.
If you are interested in Whitman Walker, they do require quarterly visits for your first year on HRT. Twice a year for your second year, and then annually after that. Each "visit" is actually 2 visits - one for blood work about a week in advance, and then a follow up with the practitioner a week later to review your results, overall health, and pick up a new prescription.
