Mr. William N. Harris III

 Welcome!

I am pleased to be the new Department Head and related theory instructor here at Diman! After having taught for six years in Rhode Island and gaining over 21 years of industry experience, I am now in my seventh year of being part of the Diman community.

I graduated from LaSalle Academy in Providence and earned my bachelor's degree in Business Administration from the University of Rhode Island.  I have also completed many additional courses at the Community College of Rhode Island, Rhode Island College and now Fitchburg State while obtaining vocational licensure in two states.  I am enrolled and working towards my Masters of Business Administration (MBA) in Management.  I currently own and operate a small HVACR business with emphasis on social responsibility, to help lower fossil fuel dependency with hopes of increasing reliance on renewable energies.          

For trade related accomplishments I possess; Rhode Island Pipe Fitter/Refrigeration License, Massachusetts Refrigeration License, EPA 608 Universal, Building Performance Institute (BPI) Building Analyst Professional Certification (lapsed), Rhode Island Dept. of Health Lead Safe Renovator/Remodeler Certification, NFPA Hot Works Safety Certification, National Grid Heating and Cooling Program Approved Contractor, Viessman Vitosol Vi102 Solar Application & Installation Certification, JLG Aerial Work Platform and Telehandler Trainer Certification and have attended and completed many manufacturer trainings.    

For educational and safety related accomplishments I possess; Rhode Island Professional Teaching Certification, Massachusetts Professional Teaching Certification, DESE Sheltered English Immersion endorsement, OSHA General Industry Trainer and Construction Industry Trainer for 10 and 30 hour courses, HVACR Excellence Certified Subject Matter Educator, and ESCO Institute Testing Proctor.

I enjoy spending time with my wife, two children, family and friends, performing home improvements/renovations, cooking and fishing.
