Braco was born Josip Grbavac in Zagreb, Croatia, in November 1967. He earned a degree in Economics in Croatia, became a husband and a father, but made healing his mission after the devastating 1991-1995 Croatian War of Independence. His mentor was Serbian healer Ivica Prokic, author of 13 books, whom he met in the autumn of 1993, and who renamed him Braco, meaning "little brother". Prokic died in 1995, and Braco continued his work. Initially he saw people one on one, however due to the large number of people who started coming to see him, he began gazing at groups. 
In a public gazing session, Braco stands on a podium and silently looks at the members of the audience for a period of five to ten minutes. There is a ten minute period before for introduction, and another after for post-gaze meditation. Supporters say during the gaze time they can feel tingling, see energy or a golden aura, experience peace or relief from pain.  Braco himself does not call himself a healer or claim to have spiritual powers, and has not spoken to the press or in public since 2002, saying "it's too big to explain." Participants and event organizers say that his gaze has healed physical diseases such as cancer and respiratory disease.Believers say Braco's physical presence is not necessary, and gazing at a picture or video of him can be sufficient for healing.
Braco's Croatian events are claimed to attract tens of thousands, totaling over two hundred thousand per year. He has toured the United States several times, including Hawaii, Pennsylvania and Connecticut in 2010, Miami and Portland, Oregon in 2011, San Francisco, New York City, Maryland, and again Miami in 2012, and Miami and Los Angeles (Pasadena) in 2013, attracting hundreds or thousands. Braco's American events are organized by Jane Sibbett, former actress from Friends, who says she first met him when hired to do a documentary about him, The Golden Bridge. As of 2013, she has now produced 4 documentaries and travelled internationally with Braco.
Croatian rock star Boris Novkovic wrote an entire album celebrating Braco called "Thank you Braco."  An American supporter, Angelika Whitecliff, authored the self-published book 21 Days with Braco (2009, ISBN 978-0984297009).
When not touring, Braco holds gazing sessions at his center in Zagreb Croatia. 
In her column for the Committee for Skeptical Inquiry, Karen Stollznow wrote that since all reports of healing are anecdotal and that Braco's alleged healing abilities have never been proved under test conditions there is no scientific evidence that Braco's gazing has any benefits at all. The article also disagreed with Braco's statement that he makes no claims of healing abilities, saying: " However, the 'no claim' claim is disingenuous; whether the claims come from the public or his crew, the claims are promoted by and therefore made by Braco."
