About Elco
Elco Marquez is a bilingual provider who sees adults at the Port St. Lucie office in English or Spanish. He earned a bachelor's degree in biomedical sciences at AdventHealth University in Orlando and completed post-graduate medical studies at Barry University in St. Petersburg. His route to psychiatry was personal: his mother's depression, a close friend's PTSD, and years of emergency room work all pointed him in the same direction.
Marquez treats anxiety, PTSD, depression, and mood disorders. He understands from the inside how these conditions affect families, and he brings that empathy to patients who are frightened, ashamed, or skeptical about treatment. His emergency background also gives him a clear sense of when a situation is urgent.
He leans on empathy and listening to build patient confidence, and he explains medication choices carefully so patients know what to expect in the first weeks. Spanish-speaking patients on the Treasure Coast, where bilingual psychiatric providers are scarce, can see him without an interpreter. He is accepting new patients at the St. Lucie West office just off I-95, which serves Fort Pierce, Jensen Beach, and the Tradition area as well as the city, and telehealth is available for follow-up visits.
