Description of Practice :

I am part of a well established and respected dermatology private practice. We have three locations to serve San Antonio; Shavano Park, Helotes, and Westover Hills. I offer the highest quality care to patients with the full spectrum of dermatologic conditions. I see patients of all ages from kids to the elderly. I enjoy practicing medical, surgical, and cosmetic dermatology. This means I take care of patients with everything from acne to melanoma. My practice also offers patch testing to help manage patients with dermatitis, narrow band UVB to help with inflammatory skin diseases, and ALA-PDT to help patients with precancerous growths known as AKs. My office also offers a full menu of cometic services from light chemical peels and non-invasive body sculpting with my aesthtician to fractional CO2 resurfacing, botox and fillers administered by myself. I am a certified Expert Injector which reflects my expertise in non-invasive facial rejuventaion. Lastly we also participate in clinical trials of medications to treat a variety of dermatologic conditions like acne, psoriasis and actinic keratoses.
