Alan Bleberstein

Cornerstone's President

Having been an Electrician most of his adult life, he has always loved this line of work. Alan went through a 4 year apprenticeship program, working for various electrical contractors and on a variety of projects. Wherever he worked he was always promoted due to his eagerness to expand his knowledge and his love of this work.
In 2005, Alan took everything he owned and with a small Astro van started Cornerstone Electrical Contractors. His reputation for quality, knowledgeable work soon spread, and he quickly found the business growing. Cornerstone Electric has maintained that growth and positive customer relationship throughout the years. Alan’s ability to instill his values of the business into the employees is what helps this company continue to grow.
Alan is married to his very patient and lovely wife, Margaret. He has three daughters, three sons and multiple grandchildren that help keep him active.

“I love finding solutions to problems, whether they are more innovative methods or empowering the workforce, it keeps me motivated every day.”
