  • Our Principal Investigators are Board Certified Dermatologists and Certified Clinical Research Investigators with many years of extensive experience. They are located on-site and are available full-time.
  • Our Principal Investigators evaluate each and every study subject.

Our patient/subject target population consists of the following and includes males and females of all age groups:

58% Hispanic
23% Caucasian
16% African American
1% Asian
2% Other

Our subjects give us several reasons why they decide to participate in our Clinical Research studies. The ones they most often mention are:

  • To help in the development of new medications that may offer better treatment or even
    cures for chronic diseases.
  • The availability of diagnostic tests and medical evaluation of a particular disease or medical condition without worrying about the cost.
  • The Hope for a new approach or treatment that finally offers some relief. For all subjects' database management, we comply with privacy and confidentiality of all HIPAA regulations.
