What Our Patients Say

Janet Lin, MD
5 Stars  Dr. Lin was the first person I saw at a new dermatology practice. I was impressed that from visit to visit she seems to remember me, my conditions, etc. because of having a technician in the room to document - good records are kept of various lesions, sizes, locations. She was quickly able to identify that a mole was formerly 4mm and now 9mm, and firmly but nicely told me that she REALLY wanted me back that same week for a biopsy. Good thing she did because it was positive for melanoma. –

5 Stars  Highly recommend Dr. Lin if any family or friends need a dermatologist. She was very professional, courteous, caring, and educated me about my skin issues (chelosis, random rashses, & toenail fungus). Very happy with my visits. Thanks Dr. Lin :) –

5 Stars  Dr. Lin is a wonderful doctor! I began seeing her about a year ago and have been extremely impressed. Dr. Lin carefully evaluated my diagnosis and then explained various treatment options. Most of the treatment plan she provided consisted of medications and methods that were never offered by previous dermatologists I’ve seen over a 10 year span. My condition has improved greatly and I have learned so much about my skin condition, due to Dr. Lin’s expertise. I highly recommend her!! - Aila Brown –
