Phoenix, AZ |
Dr Machnau knows her dermatology extremely well, I always feel she can answer all my questions and is open to them. She is easy to connect with and really takes the time to make me feel heard. She treated a difficult skin condition and worked with me to find the treatment that worked with skill and compassion- would recommend to anyone! Very easy to schedule and wait time is only a few minutes.

I've been a patient of Dr Machnau for several years and have followed her to new(ish) practice. I've found her very staff very through, courteous and have a few times where the wait was 5-10 minutes but never any longer. "Doc" has always been very detailed, asked a lot of questions, made sure to answer mine and is always been pleasant with me and my wife. I wish more doctors asked as many questions and were as thorough as Dr Machnau. I would, and have, recommend my "Doc" to others.

Dr Machnau is a perfectionist. She takes her time explaining procedures and I've always felt comfortable with her knowledge etc.
Was very demanding and did not always provide accurate information. Would not recommend.
