My name is Guilherme Bretas Guimarães. I am a psychiatrist and a specialist in bipolar disorder. In this field, I see patients and conduct research at the Bipolar Disorder Research Laboratory at UFRJ (BiPoLaB), where I am beginning my master’s degree under the supervision of the distinguished Professor Elie Cheniaux.
I completed Dr. Renato Silva’s specialization program in mood disorders—he is one of Brazil’s leading experts in the field—as well as Dr. Diego Tavares’s program at the USP Mood Disorders Research Group.

Dr. Guilherme Bretas sees patients at private offices in Ipanema and Barra da Tijuca and also offers reduced-fee appointments at Clínica Escola Social Florescer. At this clinic, appointments have an educational purpose and are always accompanied by students who observe the consultations, with up to three students present at a time. This provides them with practical experience in a supervised, welcoming environment while ensuring high-quality care for the patient.
