Also surviving William are his six grandchildren, Alaina Rexer, Camren Rexer, Amanda Rood, Brianna Rexer, Jaedynn Rexer and Colin Rexer. Growing up in Brooklyn, NY the third oldest of six siblings, “Billy” developed a thirst for knowledge, passion for business and work ethic that lasted his entire life. Influenced by his intelligent and highly respected father, a NYC cardiologist, Billy became an accomplished student skipping ahead 2 years to graduate high school at the age of 16. During his childhood, he developed interests in business from selling a variety of wares from a makeshift cart out of an old Hoover vacuum, to becoming a premier player of both handball and basketball on the courts of Brooklyn. Billy’s reputation on the basketball courts even landed him a tryout with the NBA’s New York Knicks. Upon graduating high school, Bill attended Wagner College in Staten Island graduating in 1959 with a Bachelor’s degree in Economics. From there, he landed his first sales job with Turco Chemical in Baltimore, Maryland. With success and surging sales, he was assigned to a dormant territory in Binghamton, NY to revitalize the area for Turco. Armed with a map to find this place he had never heard of, Bill found the path for the rest of his life. After arriving in Binghamton, Bill met his future wife, Gloria and they were married in 1963. In 1966, he had the opportunity to own and run his first business, Flavor Kitchens. Additionally, he went on to operate and led R&R Sales, Binghamton Cold Storage, and Binghamton Tobacco all under the umbrella of the “WFR Group.” In 1982, he started Amrex Chemical Co. Inc., returning to his similar roots at Turco. Amrex Chemical Co. Inc. has been in business for over 40 years with his children now carrying on his business legacy. Bill loved his field of work and was actively working until the recent decline in his health. Bill was the ultimate salesman and entrepreneur. There was nothing he liked more than meeting with new and existing customers. He was extremely knowledgeable in all types of industries and loved problem solving with his customers. Over the course of his career, his customers became good friends, whom he valued deeply. He will be remembered as a man always willing to help someone in need.
