My residency training was completed in 2008 in San Antonio at the San Antonio Uniformed Services Health Education Consortium. While on active duty, I served as a Brigade Surgeon in Afghanistan in addition to working as a dermatologist and faculty member in the family medicine and internal medicine training programs at Fort Hood Texas and Tripler Army Medical Center in Hawaii. My experience as a dermatologist includes practice in all realms of dermatology. I have a special interest in treatment of patients with severe psoriasis and other inflammatory skin disorders."

Dr Guerrero was very professional, personable, knowledgeable and made me feel very comfortable during my visit. I appreciated the online new patient forms that I could print out. The staff were also pleasant and efficient. My time with the doctor was easy and not rushed. She listened carefully to what I had to say and explained what was going on in plain English - easy to understand.

Excellent experience. Front office staff makes all feel welcome and are very polite and informative. The doctor and assistant are warm and take the time to explain all that is going on and going to happen. Throughout they are constantly talking to the patient to make sure there is no pain and good to proceed. Talk about exceeding expectations!

I seen Dr. Guerrero for a wart on my foot and she was great with explaining the options to treat it. During the treatment she explained what she was doing which helped me.
in Honolulu, HI |
Very thorough and amazing beside manner! I have seen 3 dermatologists in the past, and she is the only dermatologist who actually really listened to me and understood how bothersome my mild psoriasis was to me. I would most definitely recommend her to anyone with a skin condition.
