Ray founded Biomedical Systems in 1975. He is a visionary who continues to anticipate the changing needs of healthcare related issues and responds with a do-it-now philosophy. Under his leadership, Biomedical Systems has grown into a global organization offering clinical trial services, physician/cardiology services, and medical products with offices in North America, Europe and Asia serving several different healthcare markets.
A consummate entrepreneur, Ray founded Landshire food systems, a manufacturer and distributor of packaged goods in 1959. He developed it into a multimillion dollar enterprise with franchises in 37 cities throughout the United States before selling it to the Southland Corporation (parent company of 7-11) in 1977. He is probably one of only a handful of people in the United States to have built – from scratch – two highly successful, unrelated international companies in Biomedical Systems and Landshire Food Systems. Ray is an inventor and holder of several patents, including products developed for Biomedical Systems. He has served on 15 corporate and civic boards in the Greater Saint Louis area including two law enforcement organizations: The Medal of Valor and The Backstoppers, Inc.
Ray is the founder of the Minority Economic Development Corporation (MEDC), the first organization of its kind designed to identify qualified minority individuals and facilitate their participation in “mainstream America” by pairing them with successful franchisors. In 1989, Ray formed Hand-Up (Helping a Neighbor Develop Unlimited Possibilities), a volunteer organization which helps families avoid falling into the cycle of poverty through financial assistance and counseling. Ray pioneered several additional assistance programs, including a program to provide hundreds of thousands of meals to disadvantaged children with the cooperation of the St. Louis Mayor’s Council on Youth, the United Auto Workers, and U.S. Department of Agriculture. In 2011, Ray’s fondness for children was shown again as he built the playground for the Guardian Angel Settlement Association, an organization headed by Rev. Jerry Morales that has been serving the needs of children and teens since 1859. For the 2011-2012 school year, Ray donated 26 electrocardiograph (ECG) machines to the St. Louis Public School Systems. These machines will be used by students to improve their knowledge of the cardiovascular system as well as gain important training that will help them in the future as they apply for healthcare related positions. This is the first year of an ongoing program with the school district.
Ray, a veteran of the Korean War, served in the United States Army in Korea from 1953 thru 1955. Upon his return he earned a Bachelor of Arts in Business Administration from St. Louis University. He continued his graduate work at Washington University in St. Louis. Ray is a 1960 business school graduate of SLU who received the University’s “Distinguished Alumnus of the Year” award in 1989. Throughout St. Louis, he is widely known as an “Entrepreneurs’ Entrepreneur.” He was inducted into the inaugural class of the St. Louis University Entrepreneurial Alumni Hall of Fame in 2007. Selected from over 100 distinguished nominees, Ray was honored in the Hi-Tech Category as an “Individual who has displayed the characteristics of entrepreneurial leadership as a founder, owner or top manager of a firm identified as a high-technology business.”×
