About
Dr. Rosana Lastra-Castellucci is the founder and sole physician at Head2Toe Pediatrics in St. Petersburg, Florida. She holds board certification in pediatrics and earned Fellowship status in the American Academy of Pediatrics (FAAP). With over a decade of pediatric experience, she brings both clinical depth and a deeply personal perspective to her work.
Dr. Lastra became a mother in 2022, and that experience sharpened her understanding of what families actually need from a pediatrician. She grew up in a tight-knit Puerto Rican family and credits that sense of community as a guiding force behind the practice she built. She speaks both English and Spanish fluently. Her clinical passions include newborn care, lactation support, developmental screenings, and managing chronic conditions such as asthma, eczema, and ADHD. She is also a strong advocate for vaccine education and community health outreach. Local and national media have featured her regularly, including WFLA Daytime TV, the Tampa Bay Times, Channel 8 News, St. Pete Life Magazine, and Voyage Tampa. She has also appeared on the My DPC Story and The Doctor Whisperer podcasts.
