About

Richard Greenwald loves to teach. When in elementary school, Rich taught friends about things he found interesting. He dreamed about teaching and eventually taught in the Shaker Heights Schools. His father had a large mechanical engineering/contracting company and Rich eventually became a part of that company. He went to trade school at night, while learning the rest of his business by day. After 11 years, he was vice-president, and state certified in HVAC, welding, boilers, fire sprinklers and backflow preventers. Rich started his own company and soon had ten employees. He became certified as an electrician.

After 30 years of contracting, Rich joined Schaeffer Manufacturing Company in 2005. Rich specializes in troubleshooting lubrication problems, teaching seminars, becoming friends with his customers and making his customers' lives easier and more profitable. Rich is now fulfilling his dream by teaching the art of lubrication.
