Internal Medicine and Infectious Disease

Only accepting current Gonzaba Medical Group patients for Infectious Disease

Dr. Castro-Pena was born and raised in Bogota, Colombia. When she is not at work helping her patients, she enjoys spending time with her family including her beautiful daughter.

Since childhood, Dr. Castro-Pena has had a passion for helping others. Following her passion, she chose a career in the medical field, so she could provide help to support a group of patients who are most in need.

Dr. Castro-Pena joined GMG in 2016. She chose Gonzaba because of the location of the clinics and felt a connection with the patients that they serve.
