I have gone to Dr. Mary Fredenberg for 30 years. She is the best dermatologist I have ever used. That is why I have seen only her for the last 30 years.

Dr. Fredenberg is an excellent doctor for cosmetic procedures. She is very caring and even suggested an alternative service to save a lot of money.

I got called back on time, which is always appreciated. Dr. Fredenberg was very cordial and thorough during my screening, even noticing a minor scratch on my arm that my dog had given me two weeks ago. I had two minor procedures performed which only stung a little due to the adequate amount of local anesthetic. All in all, a very nice visit.

Dr Fredenberg is an excellent dermatologist. She us professional and knowledgeable in her field. She communicates in a way that I (a lay person) can understand. Ive never had to wait very long to see her.

I enjoy going to Dr. Fredenberg because she is thorough and will explain anything until I understand. I was almost late for my appointment and the staff was still pleasant and efficient. Thank you!

I’ve been going to Dr. Fredenberg at North Valley Dermatology for about 30 years. She’s amazing! I’ve used her for both medical and cosmetic and obviously I’m very pleased.

Patients are seen in a timely manner. Staff is friendly and professional. Dr. Fredenberg addresses all concerns and is sensitive to patients concerns and needs. Staff goes the extra mile to accommodate personal needs such as getting lab results expedited.

Always a good experience. Dr Fredenberg takes time with me...never rushed. Her staff is very efficient with no wait time.

Dr. Fredenberg has been my dermatologist for well over a decade. During that time she has always exemplified the height of medical expertise and professionalism in each dematological situation I presented to her. I have appreciated her calm manner, respect for her patients and intuitive approach. It is a privilege to be her patient.
