Applied Professional Services (APS) was founded by a retired Houston Texas police detective and native-born Duluthian in 1995. The firm focused on insurance fraud investigations before adding process service and security. In 2020, the firm was purchased by a long-time former employee and the security division was sold to a national security firm. Today, APS Investigations is the Investigative Division of Terch & Associates LLC, a Duluth-based consulting firm. Headed by Justin Terch, President and Tyler Rikkola, Director of Investigations, our firm continues to grow and provide services to the general public, insurance industry, and legal community.
