SALEM – Marisela Marrero doesn?t just play a doctor on the TV network Telemundo, she also works as an emergency medicine physician at North Shore Medical Center.The busy doctor recently landed a gig at the Spanish-language channel, where she informs viewers of medical-related issues in her fast-paced segment, “Medical Minute.”?I just knew it was going to happen someday,” Marrero said. “I remember telling people when I was in college that this was my plan and that I was going to have a television show, and now I do.”The Harvard and Yale educated doctor began her broadcasting career at Boston Neighborhood Network (BNN), where she earned her TV chops co-hosting medical segments a couple times a month.?At first I was invited on as a guest, then I was a substitute co-host and I ended up doing the medical segments in English and Spanish, which were used as commercial breaks,” she said.After honing her skills for more than two years at BNN, Marrero?s co-host on the show ended up getting a new job at Telemundo, and helped her arrange a meeting with officials to pitch a medical show for the network news channel.?I explained that there?s a big need in the community for a medical show in Spanish because no one out there is doing this,” she said. “So I was finally able to put this into practice with Telemundo.”Marrero?s show began airing in January, and touches on a wide range of topics such as as stroke, autism and carbon monoxide poisoning. Viewers are also invited to visit Marrero?s blog and submit questions on the channel?s Web site at www.holaciudad.com?TV is a far better venue for the Latino community, because they don?t read the pamphlets out there on medications or conditions and it?s very sad,” she said. “I think it?s a cultural thing, because the Latino community puts a lot of trust in doctors and they don?t ask as many questions, they just take whatever medicine is given to them.”Because of the disconnect between the community and doctors, Marrero said she wanted to help bridge that gap and offer medical-related assistance. Having grown up in Puerto Rico, Marrero moved to the United States 12 years ago and earned an undergraduate degree from Yale University, a medical degree from Harvard University and trained at Massachusetts General Hospital and Brigham and Women?s Hospital.?I always thought that when I finally had a TV show, it was going to be on actual things that I see everyday so that I can help people,” she said. “I encourage people to the go to the Web site and ask questions, which I will gladly answer.”To send Marrero a question, type her name in the search bar and click on her link.
