Our Senior Leadership Team

Dr. William S. Spears — Founder

Cenergistic’s Founder was serving on his local school board when the district embarked on a program to air condition 22 schools (representing two-thirds of the district’s total schools). Engineering projections said the project would increase the district’s annual electricity costs from $1.1 million per year to more than $3 million annually — an increase the district could not afford.

Dr. Spears combined proven business principles, his long-time interest in heating, ventilation and air-conditioning systems and a process based on discipline, measurement and accountability to create a program that would reduce energy use while ensuring comfort for building occupants. His program was implemented district-wide, and after tripling the district’s air conditioning load, the electricity bills actually decreased to $900 thousand dollars in the first year.

Word of the district’s success spread, and a state Public Utility Commission official asked Dr. Spears to help another district in need. That district happened to be in his hometown (Lubbock, TX), and they readily agreed to be the first client for a new company.

Thirty-one years later, Cenergistic has helped more than 1,400 clients achieve significant savings without capital investment. The company has been awarded Partner of the Year or Partner of the Year - Sustained Excellence Winner by the United States Environmental Protection Agency’s ENERGY STAR® Program nine years in a row, and is the EPA’s most active Service and Product Provider for ENERGY STAR building certifications.

Dr. Spears has 34 years of experience in public school, college, university, large church and healthcare energy management. He served the Wichita Falls Independent School District as Trustee, Board Secretary, Board Vice President and Chairman of the Facilities Committee for six years. He is a member of the American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc. (ASHRAE) and the Association of Energy Engineers (AEE).

Dr. Spears earned his Doctorate of Business Administration Degree from Wayne Huizenga Graduate School of Business and Entrepreneurship at Nova Southeastern University. He holds an MBA from Wharton School at the University of Pennsylvania and a Bachelor’s of Science Degree from Oklahoma State University (OSU). In 2004, the Spears School of Business was established at OSU.
