Okay, let’s break this down. John has a broad range of skills, including leadership, teaching, and technical expertise like data analysis and graphic design. He’s also certified as a Cardiac Device Specialist, which adds a layer of clinical expertise. Location is Baltimore, MD, which is a mid-sized market. Considering his skill set and experience, I’d estimate his hourly rate to be around $125. This is slightly below the national average for a leader with technical expertise, but takes into account the regional market. Some similar roles in the Baltimore area might pay $150–$200 per hour, but John’s unique combination of skills and certification brings him closer to the lower end of that range.
