Although Rosenfeld Einstein (RE) has ascended into its third-generation of family ownership, the company's philosophies still reflect the traditional values of its founding father, William Rosenfeld. RE is a full-service, independent insurance agency and consulting firm specializing in business and personal coverage, employee benefits, financial planning, wellness programs and workplace safety consultation.

Rosenfeld established William Rosenfeld Insurance Inc. in 1933 in North Carolina. After five years, Rosenfeld moved his family and business to Greenville, S.C., where the company still resides today. Concluding his military services after World War II, Rosenfeld continued to grow his business by providing his clients with life insurance and employee benefit programs, and brokered to other agencies until Aetna became the primary carrier.

In 1958 Rosenfeld's son-in-law, Nathan A. Einstein, joined the firm, and was soon followed by Albert Voss, who both led the company and formed Rosenfeld Einstein & Assocs. The name was then shortened to Rosenfeld Einstein. Today, RE is led by president Dan Einstein and principals Howard Einstein, Nathan Einstein and Albert Voss.
