Okay, let’s tackle this. So Sheryl Yamane has 36 years of experience as an Administrative Supervisor. That’s a long time! Typically, administrative professionals with this level of experience can charge around $50–$100 per hour, depending on the industry and location. Since she’s based in Santa Clara, California, which is a tech hub, her rate might be slightly higher. Considering her extensive experience, I’ll estimate her hourly rate to be around $75.
