I’ve been seeing Dr. Robles for 2 year, but this time I saw Alexandra and she was amazing as well! I had a terrible eczema flare postpartum and explained that I’m currently breastfeeding. She made sure to research what treatment wShow moreould work best to control my flare while still being able to carefully breastfeed my baby. She listened to all concerns that I had and as very detailed about treatment. She’s given me relief while trying to figure out the next step. Highly recommend!

I am a 76 year old woman who never used sunscreen until I was 50 years old. Needless to say I have lots of issues with sun damaged skin. Alex was very concerned and helpful, treating many areas that I pointed to that were bothering me and also treating areas of potential skin cancer that I had not been aware of. I thought she was great!!! Karen Huigens
