Roberto Ortiz, MD, AAHIVS

Medical Director

Roberto Ortiz, MD, brings more than three decades of experience in HIV and STD treatment to BLISS Health. He earned his medical degree from the National University of Colombia in 1989 and moved to Florida in the early 90s.

Dr. Ortiz began his career in the field of research, pioneering the clinical trials that led to the discovery and approval of the very first HIV antiretroviral drugs. After many years of trailblazing work, he struck out on his own to establish BLISS Health.

Combining his first-hand experience in clinical research, and a very clear vision, Dr. Ortiz has created a groundbreaking, successful and robust sexual health clinic, with emphasis on HIV and STD care serving a diverse population in terms of gender, age, ethnicity, and social groups.

BLISS Health is a comprehensive, gold standard clinic that also offers case management, mental health support, and medication access for all patients, including those who are uninsured or underinsured.

BLISS offers very ambitious and forward-thinking services that cover all sexual needs, from HIV and STD testing, treatment, and prevention (use of PrEP), to mental health, including financial aid for those in need.

Dr. Ortiz believes the stigma around HIV (and STDs) is one of the biggest challenges that continue triggering new infections. This stigma it’s something Dr. Ortiz works tirelessly to diminish, not only in his clinic but globally.

As the primary investigator in all clinical trials at BLISS, Dr. Ortiz is very active in research focusing on medical intervention and social issues. He’s certified as an HIV Specialist through the American Academy of HIV Medicine (AAHIVM) and serves as a consultant to Bristol-Myers Squibb, Gilead, GlaxoSmithKline, Merck, Tibotec, and ViiV Pharmaceuticals.

In 2016, under the guidance and direction of Dr. Roberto Ortiz, Juan started BLISS CARES, a nonprofit organization in Orlando, Florida. The mission of BLISS CARES is to provide information and financial resources for people to receive medical and clinical services that can prevent the spread of HIV, Hepatitis and STD’s.
