Our Practice:


Welcome to Northeast Florida Infectious Disease Clinic with Dr. Ivan Guerrero and Yesenia Baez, ARNP. We are an independent physician's office that consults to Ascension, Baptist and Memorial. As ID specialists we are often consulted by other physicians with unique cases to assist in diagnosing and treatment of illnesses of the blood, sinuses, heart, brain, lungs, urinary tract, bowel, bones and pelvic organs. We have extensive knowledge and insight into the use of antimicrobials and their potential adverse effects, and additional training in immunology (how the body fights infection), epidemiology (how infections spread) and infection control. Our focus is on all infections, including those caused by bacteria, viruses, and fungi in the blood. We specialize in treating patients with infections due to human immunodeficiency virus (HIV), the cause of AIDS, and STIs (sexually transmitted infections) including Hepatitis C.


Notes from our Patients:


Thank You Dr. Guerrero!

You saved my knee, and probably my leg and my life!

I recently saw you about a MRSA infection and rash it caused. I was very impressed with your office. Your ARNP is one of the best I have ever encountered.
