Jenn,
You have the right to your opinion, but I disagree with you!
That she is conservative and cautious I will agree with you, but in my case I am not a spring chicken anymore at 62 and I specifically approached her on the first visit told her that I wanted to start very slow, which she was happy about as she told me that it was the opposite of what most patients wanted.
On the lab test, she told me the type of test i needed to have performed and I have been using the online 3rd party provider" that you refer to with very low cost compared to everything else. If you look at the recommended testing frequency by recognized endocrynologist associations, I believe is monthly for the first 3 months or so and then every 3 months for like a year and if everything is normal and a good hormone level is achieved then the testing is every 6 months. I have been pretty much on that schedule except my potassium has been high so she has been testing just for it more often.
Just because you don't agree with her protocol is not a reason to discredit her. She is professional and once you begin to know her better she becomes more open and caring.
Maybe she is not your type of doctor, but don't say that she is inexperienced and unprofessional please!
