Okay, let’s break this down. Leah has an MPH, which suggests some expertise in health-related fields, but her skills are quite broad. Marketing, crm, analysis, and project management are all in-demand skills. However, her location in San Francisco, a hub for tech and marketing, might not command the highest rates. Considering her skills and experience, I'd estimate her hourly rate to be around $120, which is slightly below the national average for marketing professionals in this field. This is because her MPH is not directly related to marketing, and she may not have as much experience as some other professionals in the field.
