I have not felt well for the last 4 times I've seen her, I've told her the medication change is not enough. I'm always leaving feeling like I wasn't listened to and my opinions on how I wish to to be treated are not listened to. I will be shopping for a new doctor.

Dec. 20, 2019
I've been seeing Dr. Maas for many years, where I started seeing her because of a cyst that was found on my pituitary gland. And then due to under active thyroid where she started me on medication. I was seeing a MD where she did lab work and said due to the results she needed to change the dosage/strength of my Levothyroxine. I tried to explain that Dr. Maas has said that "my normal" is everyone else's abnormal and vise versa. Needless to say I'm no longer seeing that MD any longer. I will travel wherever to see the Best and I feel Dr Maas is the Best!! Most of the time she is also out of network for me as well!!!!!!!
