About Nancy Maly (Cheng), MD

Medicine offers the deeply humbling opportunity to make a tangible difference in someone's life. I am fortunate to have had the mentorship of many remarkable physicians along the way whose guidance and support led me to this career. Practicing dermatology is a true joy and privilege. The most rewarding part of my work is the doctor-patient relationship, which serves as a daily reminder of why I chose this profession. As a fellowship-trained pediatric dermatologist, I also enjoy attending to the unique needs and skin issues of infants and children, some of our most vulnerable and inspiring patients. Music has always been an important part of my life. In my free time, I have enjoyed playing the violin in various orchestras. Most recently, I was a musician for Symphony Irvine in Orange County.

*Dr. Maly is very knowledgeable. She is the doctor that was able to figure out and help me with my condition. I was hoping that I was referred to her early on. I'm very grateful for her.

Dr Maly - is always outstanding, listens to my concerns, offers solutions and puts me at ease that most of my skin issues are manageable and not too concerning.
