Ethnic diversity, presence of a large retirement population, and a rapid rate of family growth make San Antonio an excellent place in which to do clinical research studies. In addition to common dermatological disorders, such as acne and psoriasis, San Antonio has a large population affected by heat and sunlight related disorders, including skin cancers and pre-cancerous growths, fungal infections and seasonal dermatitis. We have a catchment area of more than 1.2 million people. We also maintain several databases for those subject interested in future studies.
