He was a registered professional engineer and a member of ASHRAE who served his clients with commitment and respect. Even though Coward Eastman Co.was sold in 1975 "Charlie" continued to be part of the profession of selling until his death in 1990. He never really retired.

Carl B. Eastman graduated from the University of ME with a degree in Mechanical Engineering. He was employed by a consulting engineer in Philadelphia, PA before joining with Charles W. Coward to form Coward Eastman Co.,a manufacturer's representative company, in 1944.
He was an active member of ASHRAE and a well respected member of his profession until his retirement in 1975.

Nicholas R. Musulin joined Coward Environmental Systems, Inc. (CESI) in 1994. He used his marketing degree from Rutgers University to effectively promote and sell engineered products while building a reputation as a dependable and knowledgeable sales representative. Nick and his wife Lynne purchased CESI in 2001 and built a very successful business based on his dedication to his customers, principals and employees. Nick's leadership helped CESI grow to be one of the most respected sales rep firms in the Philadelphia trading area. Nick's untimely death in 2009 left an emptiness in the minds and hearts of everyone who knew him.

W. Wicks joined Coward Environmental Systems, Inc. (CESI) in 1985 after spending 45 years in sales and management for a Midwest manufacturing company and a sales engineer for a Philadelphia sales rep firm.
