Being a mom is incredibly stressful. Choosing the right doctor is the key to a healthy pregnancy for both baby and mommy. Xana Miguélez is an attending physician in the department of obstetrics and gynecology at Mount Sinai Medical Center in Miami Beach. Fully bilingual, knowledgeable, compassionate, patient, and willing to field panic-filled calls and listen to teary-eyed encounters about pregnancy, Dr. Miguélez is unique. In her spare time, when she's not with her kids, she is the president of the nonprofit A Stitch in Time, a group of volunteer gynecological health-care professionals that provides surgery and treatment to needy women in remote parts of the world. She has performed surgeries in Bangladesh and plans to travel with her team to Uganda this summer. She was educated in Spain and completed her residency at the Mount Sinai School of Medicine in New York. She also holds a master's degree in reproductive and sexual health research. If you're looking for a doctor with a big heart and a big brain, Dr. Miguélez is the one. Her office is open from 8:30 a.m. to 5 p.m. Monday through Friday.
