About George Brennan

Have you ever heard of the "The 3-30-300 Rule"? It is quite basic and goes as thus: • The average natural spend for utilities is $3 sq. ft.• The real estate average national spend is $30 sq. ft. • The human costs are $300 sq. ft. national average. Yet, we find companies trying to save 15-30% on their utilities when a 10% reduction of real estate expenses would exceed their total utility spend and a 1% productivity boost would exceed the real estate savings and utility costs. We invert this “pyramid” to attack the more important contributions to bottom line.

Listed skills include Strategy, Management, Marketing, Strategic Planning, and 31 others.
