Given Gary's extensive experience in consulting, coaching, and entrepreneurship, I'd estimate his hourly rate to be around $150. This is based on national averages for executive coaches and consultants in the Greater Seattle Area, who typically charge between $100-$250 per hour. Gary's 111-year tenure at CGI also suggests a high level of expertise and dedication, which could justify a premium rate. However, without specific industry benchmarks or salary data, I've opted for a conservative estimate.
