Okay, let’s tackle this. So Nicole Sealfon has skills in data analysis, research, and policy analysis, which are in demand. She has a degree from The George Washington University-Milken Institute School of Public Health, which adds some prestige. However, her role and location are not specified. Typically, public health professionals with similar skills and education can charge $50–$100 per hour. Considering the lack of specific details, I’ll estimate a lower rate. Maybe around $75 per hour, which is a reasonable estimate for a public health professional with these skills and education in Baltimore, MD.
