dr.weiss has been a major support since meeting her and having her as a provider. she doesn't just throw medication and false information at me but work hand in hand to make sure i take the proper steps for things and also deflects me away from incorrect information

dr. weiss is pragmatic and optimistic. she explained treatment options while listening to me as a patient and incorporating my concerns to form a reasonable plan. she communicated that the process is difficult and inefficient while emphasizing that unsuccessful cycles are not my fault. she made me feel like i still have agency in a very difficult process that often leaves people feeling as if they are at the whim of other forces around them or in their bodies.
