This comprehensive skill set means David Castlegrant & Associates can act as a “one-stop” advisor on all facets of operating a small business, from project management to space utilization analytics. Starting with just two clients via his professional network, DCA grew steadily and reinvented itself to meet clients’ changing needs and technological advances. In the late 1990s, Castlegrant brought on a business partner, Deborah Gantos (whom he later married), to expand the firm’s training, human resources, and coaching expertise. Under their leadership, DCA evolved into a family-owned business offering services such as staff development, executive coaching, web and graphic design, and low-cost, high-impact marketing solutions..
