I have always seen regular "family doctors" for my hormones. I have never had long waits. Even when I first started, the doctor prescribed mine right away, after a proper examination.
You may find that "specialists" will almost always require lengthy waiting periods. This may be even worse if your insurance requires you to have a referral from your primary care, which is the one that should probably be prescribing your treatments in the first place. Personally, I have never had my primary care doctor refer me to anyone else just for hormones.
