Altos Pediatric Associates

Nurse Practitioners

Nurse Practitioners are advance practice nurses with additional training, often at the Masters or PhD level, who provide healthcare services similar to those of a doctor. They have a unique approach focusing on health promotion, disease prevention, and parent education. Our two highly qualified pediatric nurse practitioners meet with families for well visits and acute illnesses for children of any age, but particularly at the six-month and fifteen-month well visits, to promote nutritional, safety, and sleep counseling. They always practice under the supervision of the Altos Pediatrics pediatricians.
