After completing her pediatric training, Dr. Mosqueda began providing care in community clinics, private practice, and the hospital. As a pediatric hospitalist, she attended many deliveries and took care of newborns and patients in the emergency department.
Along with becoming a pediatrician, her other greatest accomplishments include raising her family and moving to South Pasadena with her husband. The couple has three wonderful children and spends many weekends on the soccer field with her youngest son.
Dr. Mosqueda enjoys spending time with family, walking her dogs, and continuously discovering all that South Pasadena and the surrounding communities offer.
Dr. Mosqueda has come to value the strong relationships between doctor and patient. However, over the years, doctor visits have transformed into rushed 10-minute appointments resulting in impersonal medical care. For this reason, she opened Yuli MD Pediatrics.
Why Yuli? That's Dr. Mosqueda's nickname given to her by her late mother. In her memory, she adopted the name for her practice. Yuli MD Pediatrics, an ideal medical practice, focuses solely on the patients, their families, and their needs.
