I went to Spectrum for the first time this week & saw nurse practitioner Katherine Weidenbach. I have never been to a doctor that made me feel as though each & every last concern was addressed. There was excellent communication between the medical assistant and her before even entering the room. When she did come in, she repeated back everything I told the m.a. to make sure she had it right. As we were discussing my acne, she talked about everything from a scientific perspective which I align with and appreciate. She also did not insist on me trying anything that I said did not work in the past (unlike every other dermatologist I have ever been to). Obviously this review is pending the results of the treatment she prescribed, but I am thoroughly impressed so far!
