Kirchner had started the PVF company in 1950. It has grown steadily from tiny quarters at the start to today's 150,000-sq.-ft. facility. The company is headed today by President Edward Zimmerman, Vice President of Operations & Human Resources Susan Kirchner, and Vice President of Sales & Marketing Jack Joiner.
Although Maria Kirchner was not a member of any industry associations, she was active in the American Heart Association and other local charities and instrumental in obtaining a Minority Business Enterprise and Woman Business Enterprise status for government contracts. Survivors include her daughters, Stacie and Susan, grandchildren and great-grandchildren. Memorial contributions may be made to Hospice of Baltimore, 10085 Red Run Blvd., Suite 401, Owings Mills, MD 21117.
