Wyman Energy, formerly Wyman Oil Company Inc. is the oldest heating oil company in Manchester having been in operation since 1953.

Rocco DeSimone Sr. began working for Frank Wyman in 1958 and purchased the Wyman Oil Company in the early 1980's.

Rocco DeSimone Sr. retired in 1999, leaving operations for son, Rocco Jr., and son-in-law, Bill Gochee. Bill Gochee has worked for Wyman Oil since 1979 first as a service technician and now as Vice President and Service Manager. Bill's extensive knowledge of heating equipment and excellent rapport with customers makes service and installation a breeze. Rocco Jr. began working for Wyman Oil upon graduating from Western New England College in 1993. Like Bill, Rocco began at the ground floor, first delivering oil, and then service as well as working side by side in the office with his father.

Now president, Rocco continues to put customers first, making sure that they receive knowledgeable and courteous service that sets Wyman Oil apart from competitors. In continuing their quest for optimal service, Wyman Oil has recently branched into delivering and servicing propane. Therefore, renaming themselves... Wyman Energy Services Inc.
