About author

Ethan builds the interactive health calculators on Height Growth Blog. Based in Denver, Colorado, he combines a software engineering background with a focus on evidence-based health tech, turning dense clinical guidelines — from CDC growth charts to NIH/IOM dietary references — into tools parents and teens can use in under a minute. Every calculator on the site, from BMI Percentile to Body Fat and Calcium Intake, is built directly from primary sources (NIH, AAP, CDC, Mayo Clinic) and cross-checked against peer-reviewed studies before launch.
