Okay, let’s tackle this. So Bob Gray has 19 years of experience as a nonprofit executive, which is impressive. His skills in strategic planning, philanthropy, and fundraising are in demand. Location is Baltimore, MD, which is a mid-sized city with a moderate cost of living. Nonprofit executives with his level of experience typically charge lower rates, around $100-$200 per hour. However, considering his leadership role and education, I’ll estimate around $125 per hour. This is slightly above the average rate for nonprofit executives, but still reasonable given his expertise and experience.
