Marsha Diane Spitzer is a Hillcrest pediatrician at 4094 Fourth Ave, running an independent practice on the Fourth Avenue medical corridor between Washington and University. The office handles the full well-child schedule from newborn visits through adolescent physicals, a panel that overlaps with the larger group at Perlman Pediatrics Hillcrest a few blocks south. Common reasons for a visit include immunizations, school and sports physicals, ear infections, and developmental screening. Pediatric endocrine workups for growth, thyroid, or early-puberty concerns refer out to Children's Healthcare Pediatric Endocrinology, the subspecialty office in the same Uptown medical cluster. The most involved cases are complex chronic pediatric patients who need ongoing coordination between primary care, subspecialty clinics, and Rady Children's Hospital.
